In America they call it the clown shoe; in the UK we call it the bread van but whatever you choose to call it the Z3 Coupé remains an incredibly special and unique machine. #BMW attempted to recapture the magic of its quirky miniature shooting brake with the E86 Z4 Coupé and while it was arguably a better car, it was also a lot more conventional and lost a lot of the appeal of its quirky forebear. Being unconventional may have caused people to fall in and out of love with the Z3 Coupé throughout its life but standing out from the crowd has most definitely worked in favour of the eye-catching machine and that is exactly why Grant Gillum ended up buying this car.
“I wasn’t a BMW guy per se,” Grant begins, “but I knew they made a quality product. As college was ending I began researching nice used cars to purchase after graduation. I wanted a front engine, rear-wheel-drive car that could be modified and used for autocross and track days. It would also be my daily for a while. After considering several cars including Corvettes, Camaros, Porsche 944s and 928s, the Pontiac GTO (not a used car at the time), Datsuns and Nissans of many years and models, I decided on an E36 M3. I liked the styling, the daily sensibilities and the aftermarket availability. They were also uncommon and more exclusive. All that changed the day that I saw a Z3 Coupé in traffic,” he says. “I had seen a million Z3 Roadsters and wasn’t really interested in a convertible. But this was different and I wasn’t even sure what I was looking at. I certainly didn’t recognize it as a Z3. It had a BMW logo so I started researching all their models, eventually finding information on the M Coupé. All the engine of an M3 but lighter, with a factory wide body, staggered wheels and a look that was comparable to some exotics. Sold. I had to have one,” he smiles. “It took nine months of scouring the internet to find the right one.
I bought a 22k mile example, bone stock but for a Dinan CAI and a stage one tune and still under warranty. I bought it sight unseen except photos and had it shipped cross country. I realized right away too that the M Coupé was a limited production run vehicle and so would be a cheap way for a blue collar guy to own something special. I bought the car knowing it would be a lifelong project car. I’ve known plenty of grey haired dudes that sold the hot rod of their youth and regretted it the rest of their lives. Not me. Hopefully,” he adds.
Unlike other owners who buy their cars and start out with no plans for modifying, Grant knew he was going to mod the Z3 and knew exactly which direction he wanted to take it in. “I wanted to race it right away and joined an autocross club soon after buying it,” he says, and his passion for autocross is shared by his wife. “Six years ago she came with me for a day at the track. She rode along on a couple runs and decided to give it a try. Except when pregnant, she’s raced in nearly every autocross event that I have since then. Averaging our times to a 60 second run, she’s about a half second off me. She’s been as close as a tenth second off my time. I’m much more of a fundamental driver, she drives much more by the seat of her pants. As soon as she tightens up her fundamentals, she’ll beat me,” he says. While you can take any car to an autocross event, if you’re serious about this particular form of motorsport, as Grant is, then your car will need to be modified and in a focussed way that will enable you to get the most out of it, which is why virtually everything he’s done to his Z3 has been all about making it a more finely-honed, precision autocross instrument.
It’s also why the supercharger that you can see strapped to the side of the engine came last and everything else came first as the chassis, handling and dynamics were the priorities here.
Wheels and tyres were the first items on what would become quite an extensive shopping list and while aesthetics do obviously play a part, lightness was mostly the deciding factor as far as wheel choice was concerned. “I went online and found the lightest wheels I could for the car,” explains Grant. “I bought a set of OZ Alleggerita HLTs in 8x17” and 8.5”x17”. They were light at less than 17lbs (7.7kg) per corner and dropped considerable unsprung weight over the stock wheels and I converted to wheel studs too.
I ran those wheels for a couple of autocross seasons before switching the rears to the front and widening the fronts to 10” and putting them on the rear. Now they weigh 16.8lbs (7.6kg) and 17.9lbs (8.1kg) front and rear; they are light, strong and handsome,” and what more could anyone ask for from a wheel? “I also run a set of 8x18” and 9x18” ASA AR1 wheels with black centres and 2” and 3” polished lips front and rear on the street,” he adds. The 17s really suit the Z3, as you can see in the photos, especially with the fat sidewalls of the super-sticky BF Goodrich g-Force R1 tyres filling out the arches and those tyres let you know that this M Coupé means business.
With lightweight wheels and track tyres taken care of, the next item on Grant’s to-do list was the suspension, and while he started off small, things quickly escalated. “I started with H&R springs and kept them for a few years until they sagged,” he says, “then I switched to Ground Control coilovers and adjustable spring perches. But not before modding the anti-roll bars with reinforcements, adding differential reinforcements, rear shock mounts, sub frame reinforcements and rear camber and toe adjustments. Then I poly bushed it followed by aluminium control arms.
“Disaster struck at the autocross one day when the diff pulled away from the subfloor and the rear end went squishy,” says Grant. “I thought that one of the rear anti-roll bar end links had given way. That’s how I got a tube frame rear subfloor that is way stiffer than the stock car ever thought of being. I love the coilovers, of course, but the single greatest suspension mod was poly bushing the rear subframe. It really changed the way the car transitioned weight in-corner to being much more predictable,” he says. As is often the case when it comes to modding, when things go wrong, break or fail, rather than just replacing them you upgrade them so, as with his boot floor, when the clutch started to slip Grant fitted an F1 Racing stage two clutch and 14lbs chromoly flywheel as well as a stainless steel clutch line and then added a UUC short shift kit and double shear selector rod plus a Z3 2.3 steering rack. Further drivetrain upgrades include a poly differential bush, UUC aluminium engine and transmission mounts and a rebuilt diff with four clutch zero preload and 80/60 ramping, polished ring and pinion gears and a 3.64 final drive in place of the standard 3.23 item. “Before the supercharger, lowering the final drive was a really dramatic NA mod. It went a long way to help pull me out of slow second gear turns,” explains Grant.
With the suspension and drivetrain taken care the Z3 was a far sharper machine but now the car’s stopping abilities needed to be addressed. “When I started doing a lot of track days it was apparent that the stock brakes were not up to long days of abuse,” he says. “That’s when I did the brake conversion and ducting. What a difference and zero fade. I didn’t go too big on the disc diameter as I was concerned with reducing as much rotational weight as possible, as autocross is more of a low speed competition.” The Z3 now wears Wilwood six-pot Superlite front calipers with 330mm GT-48 floating discs and Wilwood Dynalite four-pot rear calipers with 312mm lightweight discs and Wilwood B pads allround, while the ducting ensures that the brakes receive plenty of cool air to deliver peak performance at all times.
Having carried out all the groundwork to make sure that all aspects of the chassis and drivetrain were at peak performance, Grant could now turn his attention to extracting more power from the engine.
Unlike our Euro-spec Z3 M models, the US cars were fitted with the S52B32 engine, based on the M52, which had to make do with 240hp and 236lb ft of torque so it’s no surprise that Grant wanted to up these numbers. “I started with keeping the engine NA and wanted to let it breathe better,” he says. “I upgraded the cooling system with a rad, water pump thermostat and cover immediately. I kept the CAI and did the M50 intake manifold exchange and I also did the BBTB at the same time. A cat-back exhaust followed and a year later came exhaust manifolds and a mid-pipe. In general I would wait until OE parts needed replacement and would upgrade at that time; that way the financial hit of modifying was lessened by taking the money I would be spending on OE parts and putting that towards upgrades.
I replaced all the water hoses throughout and the oil cooler followed when I started doing more track days, as I live a 40 minute drive from Thunderhill Raceway here in California. While on track there one day the bottom radiator hose slipped off and started spewing out coolant; I realised it had happened within seconds but even though I coasted into the pits the water temp gauge showed hot and that’s how I got the new head and I went to under-driven pulleys then as well.
“After the rest of the car was pretty modified I bought the supercharger kit. I had become a dad and my wife wanted me to do less high speed track driving and just drive autocross, so after close to two dozen track days at Thunderhill my focus changed with regard to driving. I needed just a little more low-end torque to pull me out of slow second gear turns when I didn’t want to shift to first gear at autocross,” and the supercharger kit has certainly given Grant the grunt he was after. It’s an Active Autowerke Stage 1 kit with a Rotrex C38-92 supercharger and is accompanied by numerous supporting mods. “I removed the air con, replaced the alternator, installed the power steering cooler, did the oil pan/pump upgrade and fitted an ATI Super Damper, crank pulley and carried out a CCV delete with the supercharger kit,” he says. “The baseline dyno when I bought the car was 205hp and 203lb ft of torque at the wheels; the NA mods took that up to 230whp and 222lb ft and it now makes 312whp and 262lb ft at the wheels on the same dyno. Active Autowerke claims that this kit makes 360hp on a stock car; I’ve done a lot of other work to the engine, so if they want to claim 360hp I want to claim somewhere in the 380hp range,” says Grant. “That seems excessive, though, and I usually just quote my dyno numbers,” and that’s still plenty to enjoy both on road an track, and a huge increase over stock.
While Grant has focussed mainly on the performance and dynamic elements of the car he has not forgotten about aesthetics, both inside and out. The exterior as been enhanced with Motion Motorsports front splitters and aluminium undertay, a one-off AC Schnitzer rear diffuser centre section, the roof spoiler has been raised by 8mm to enhance the roofline and Grant’s also fitted black kidney grilles, black lower mesh grilles and carbon-look roundels among other things. The interior, meanwhile, has been treated to a Momo Competition steering wheel on a quick release hub, chrome handbrake handle, E46 M3 short shift gearknob, black leather gaiter with tricolour stitching and M Tech pedals and dead pedal. There’s also a H3R black HalGuard fire extinguisher, but this was added as a necessity following a scary incident…
“While testing the car after installing the M50 manifold a fuel hose wasn’t secured completely and popped off and sprayed fuel over the exhaust manifold,” says Grant. “Thank god the car wasn’t warmed up all the way and only billowed white smoke. I pulled over immediately and ran. It continued to smoke for a long, heart-pounding five minutes. I fitted the fire extinguisher after that,” he says.
Grant’s Z3 is a focussed build that’s been taken in a specific direction and the results speak for themselves. While it looks great it’s the changes that you can’t see and that we can’t experience or appreciate that make this car. It’s the vast amount of chassis work, the brakes, the hundreds of seemingly minor secondary mods that are so important for the success of the whole and which all add up to make a such big difference. This Z3 has evolved hugely during the 14 years that Grant has owned it, from autocross machine to track monster and back to autocross beast but this time with the wick turned way, way up, becoming more and more focussed at each stage and it’s not reached its final form just yet…
“In the not-too-distant future this car will retire from competition after nearly 80,000 miles that saw it driving to almost monthly autocross events (10 months a year). I have a pile of class win trophies adding, in my small way, to BMW’s racing heritage. I’ll paint and mount the new bumper and splitters I have waiting. I’ll delete the fog lights and the antenna for a cleaner look. At that time I’d also like a nice set of multipiece step-lipped wheels,” he nods, painting an attractive picture. At that point it’ll become a different animal altogether but whether or not that will be its final stage of evolution will remain to be seen…

The #BMW-Z3M Coupé has a lot of charm; with a turbocharger and 550whp this example is one sexy Breadvan. The big-bottomed #BMW-Z3 M Coupé is something of a cult classic and while it’s not universally loved, with a turbo under the bonnet it’s hard to hate… Words: Elizabeth de Latour. Photos: Darren Maybury. #BMW-E36/7
At 22 I was driving 1.0-litre Citroen Saxo; at 22 Andrei Spirin is driving a turbocharged Z3 M Coupé, so it’s safe to say that he’s doing okay for himself. And that’s good news for the BMW world because he’s built himself a pretty tasty #Z3 M Coupé. In the UK we call it the bread van; in the States it’s the clown shoe. Whatever you call it, it’s fair to say that the Z3 Coupé was a bit of an oddball and even the M Coupé, the only version we received in the UK, didn’t exactly meet with universal praise. There was something about it, though, something about its ungainliness and bulbous rear that attracted a number of people and today it’s accepted as a bit of a cult classic.
It’s funny how the Z4 M Coupé tried to bring back that bootylicious body but was just a bit too conventional-looking really and then Ferrari went and brought out the FF, which is a scaled-up M Coupé if ever we saw one. And speaking of seeing one, when’s the last time you did? We can’t recall but it was definitely a while ago; this car is not a common sight in the wild.
So cult classic; potentially a bit of an investment; rare to boot – it’s all about keeping them standard, surely? Well, skyrocketing values never stopped anyone from modifying their E30 M3 and it’s pleasing to see someone like Andrei going all out on their M Coupé. He’s most definitely not been shy with this car.
Growing up, Andrei’s middle brother Gennady first got him into cars. Then his brother’s roommate at college, Pete, introduced him to BMWs via an S52- swapped E30 M3, which has the same engine that powers this Z3, as it happens. Pete showed Andrei the world of meets and street racing and taught him a lot about BMWs. Andrei actually now works for Pete at his company, Offcamber Motorsport, doing everything from fitting superchargers to building engines, hands-on skills that come in more than a bit handy when it comes to, say, modifying your BMW…
“My first car was also my first BMW,” says Andrei when we delve into this motoring past. “It was an E39 M5 and I learned the hard way why you should never to buy a 2000 M5 as it was an early model and constantly had issues. It was a nightmare to own but I had some amazing times in it. I also knew how to take the whole top side of the engine off blindfolded because I did it so many times. I was a typical teenager at the time. I inherited $10k from my grandma who passed away. I wanted to get an E36 M3 but at the time I only had my permit, which meant my dad was always driving with me. My dad looks like Santa Claus so he would have looked a bit odd in an M3, so we decided to get a E39 M5 instead so that he would not look too out of place. We went to go look at one which was beautiful and cheap. It had a Supersprint exhaust which was the selling point for me. It was really fast, too. The M5 was the first car I modified. I didn’t go too crazy on the mods because I was spending most of my money fixing it but my favourite mod was the electronic exhaust cut-out valve I fitted before the silencers. I mounted the switch by the sunroof button so it felt like a fighter jet when I engaged it.”
After owning an E39 M5 as a first car, the only logical progression for car number two was… another E39 M5, obviously! But when that was written off after someone ran a red light and drove into it, Andrei knew that the M Coupé was what he wanted: “After the accident I started looking around and found this Imola red one in February 2011. It was two hours away and had been on sale for a while. It had 58,000 miles on it and some very tasteful suspension mods carried out, which was the main selling point for me.” Despite being a pretty rapid machine, after owning two slabs of German muscle the M Coupé didn’t impress Andrei in terms of performance front although when he hit the twisties he quickly realised just how capable it was on the handling front. Of course, working at Offcamber Motorsports and with a taste for modified metal, the M Coupé was never going to stay (relatively) stock for long and having planned to turbocharge his ex-M5, it made sense to transfer those plans across to the Z3.
“My whole turbo setup came about after a deal that I made with my friends,” Andrei explains. “When my M5 got totalled, the drivetrain was fine and I still had an immaculate interior. My buddy, Jon Valia, who had his car featured in this magazine a couple of years ago (a turbo S38 E30 M3) had an M5 shell that he got from one of his buddies which needed a motor and interior. So we came to a deal where I would give him those items and he would build me a turbo setup for my car. The whole first part of my build was done by him; we took the motor out at his house and he started fabbing the downpipe while Pete helped do the head gasket and head studs on the motor. After a month into the build Jon had to bail because his wife had a baby and didn’t have enough time to work on the car and I felt bad about always bugging him. So we took the car to Pete shop’s and finished it at Offcamber. Pete and I worked on the car for another two months before it was finished.
“I wanted to make 500whp and S52s are more than capable of doing that on stock internals. The car currently makes 550whp on 17psi. The setup has worked flawlessly and the engine has held up perfectly. It had 100,000 miles on it when I finished the conversion and it’s currently on 150,000 miles. The car has been my daily driver for two years and it worked faultlessly with no issues. To this date I am surprised as to how the S52 handled the boost so well for so long, and it has seen a lot of racing, too.” At the heart of the turbo kit sits a Precision 6262 ball bearing turbo with a Tredstone intercooler helping to chill the intake air and a thicker MLS .140 head gasket has been fitted to lower the compression ratio, along with a set of ARP head studs. A set of 60lb injectors ensure that the engine gets plenty of fuel, backed up by a Walbro 255lph fuel pump.
Pop that huge clamshell bonnet and you’ll be greeted by the sight of, well, not a lot really as the turbo is tucked down by the side of the engine and the only bits you can actually see are the oversized induction kit and the Tial 55mm blow-off valve. It’s not a showy engine but the rest of the car’s not exactly shy…
It must be said that Imola red works so well on the M Coupé. The bold, bright colour really suits the car’s striking shape and it’s the sort of car that doesn’t really need any styling to get it looking perfect. About the only external mods here are those Umnitza headlights and the stone guards, something of a necessity due to the M Coupé’s rather wide hips. But the bulk of the visual impact is purely down to the colour and the wheels. Where pretty much everyone is going bigger, Andrei has bucked the trend and gone for a set of 17s, which is pretty much unheard of on the modified BMW scene. While these are surprisingly small they are plenty wide and a perfect fit for the M Coupé. “I always wanted a nice set of deep-dish wheels,” says Andrei, “and about a year ago I finally managed to pick up these Fikse FM10s, which were my dream wheels. I couldn’t be any happier and the best part is that they were specifically designed for the M Coupé as they were built by my buddy, Jon Thayer, who also has a turbo M Coupé.” These sexy cross-spokes measure a meaty 9.5” up front and 11” at the rear, the latter being wrapped in massively wide 315/35 Toyo R888s which help the Z3 put the power down.
Having had a taste of the Z3’s handling prowess it’s no surprise to learn that Andrei has gone to town on the suspension mods to bring out the best in the Z3’s chassis. A set of TCK S/A coilovers has been fitted along with aluminium control arms, solid monoball mounts, a set of Treehouse Racing FCABs, a H&R anti-roll bar along with an E36 M3 Convertible support brace and a Randy Forbes subframe reinforcement kit. That comprehensive suspension line-up means this Z3’s chassis is razor-sharp and that it’s not all about the straight-line speed. Awesome suspension mods are all well and good but if you’re flopping about on crappy seats you’re not going to enjoy the drive, which is why Andrei has added some decidedly unfrivolous interior upgrades. “Before the turbo setup I did a lot of road course days hence why I have the Bride seats in there, along with the harness and harness bar,”
Andrei tells us. “The stock interior from factory is, in my opinion, one of BMW’s best. My M Coupé has the two tone Imola/black interior and I wouldn’t change a thing on it.” Andrei wanted to carry over the clean, stock philosophy from his exterior over to the interior and so decided against a big A-pillar gauge pod, opting instead for a custom dash-top pod, one of just ten ever made specifically for the Z3 by a Bimmerforums member. It looks extremely discreet and houses a Prosport boost and fuel pressure gauges along with an Innovate AFR gauge. He’s also fitted a Momo Millennium steering wheel and a ZHP gear knob along with a UUC short-shift kit. From massive engine mods to a set of serious chassis upgrades and a generous sprinkling of the perfect finishing touches, Andrei has built himself one red-hot bombshell of a Z3 M Coupé. Whatever your feelings on BMW’s loveable oddball may be, this is one shoe-van-thing that will rock anybody’s world.
