I will have to start this month with a bit of an explanation – I obtained the M3 in October last year and hopefully you’ll have read last month’s piece, with me telling you about the first track day in the car etc, but things have moved on massively since then, so I will be trying to compress this year’s goings on into the next few months before things are about to start going mental in #2016 !
So the ethos as with any track/race-car, if you can afford it, is to uprate the brakes, suspension, tyres and get a good seat and harness – so this is exactly what I did…
The front brakes were changed for the #AP-Racing CP5555M1050BG.G8 kit (six-pot callipers and 368mm x 36mm discs instead of the larger 378s, to allow fitment of 18-inch wheels) with the CP6602-1001BK.G8 rear kit (four-pot callipers and 352mm x 26mm discs). I originally asked for the standard Ferodo DS2500 pads (which are not suitable for track use) to be swapped out for the brilliant Pagid RS29s, but sadly there were none in stock in the UK at the time, so went with Ferodo 1.11 endurance pads and was assured they would be up to the job and as they were an endurance pad should even last a bit longer than other pads. Naturally, being a genuine AP kit, it went on seamlessly and I couldn’t wait to try them out.
Before I could do this, and knowing how good they are from previously driven cars, a set of #KW Club Sports were ordered, so the car sat for a further six weeks until they arrived. These were fitted and the geometry was set to 1mm toe-in on the rear, with the front set to parallel, 2 degrees negative camber on the rear and 3 degrees on the front.
So that was the suspension and brakes sorted – that left the wheels and tyres. The design of the car allows it to run stupidly large tyres all round and after a bit of reading and research, it was only ever going to go one way and a set of Gloss Black Apex Racing 10x18 ET25 were ordered for a square setup. With these on their way from America the only tyres I could guarantee for the job was a set of Michelin Pilot Sport Cups – not Cup+ I might add, and certainly not the new Cup 2s, just the regular Cup 1s. Out of interest, if you want to know, to my mind the Cup 2s offer grip levels only marginally better than the Supersports and the Cup+ are like a regular Cups, but have a couple of extra water lines. If you’re track/race mad, then regular Cup 1s for the win…
So four 285, yes 285/30/18 Cups were ordered, along with a set of 10mm spacers for the front to stop the wheels rubbing the KWs up the wrong way and a 5mm spacer on the rear, just because that’s what the fastest man around the ‘Ring in an E92 M3 said he was running on that particular day!
So wheels and tyres on – wow! They looked big, mahoosive, gigantic – these are going to be a lot of fun. Only thing missing now was the #Recaro SPG XL seats. Recaro had a back order then they shut for Christmas and then racing season started, so it took over five months to get two red seats as anything other than black was a special order, as apparently not many people want red seats – who would of thought… So now we had seats and harnesses fitted, trim out, APs on, KWs on and 285 Cups with lightweight #Apex Arc-8s – time to get on track!
My first trackday of the year was at Bedford Autodrome in February, which I always do with a large group of friends from back in the Ford days. Not many of us own Fords any more, as we have seen the light and now have BMWs, Clio Cup cars and a couple of Lotus’s – you get the idea. I would like to state that I drove the car there on the standard wheels and changed onto the Cups once there – this was made easy by a stud and nut conversion like the trackorientated GTS runs as standard and I can honestly say it makes a wheel change so much easier than having to hold the rim in place and line the holes up etc. I’m sure you have all done it before and know it’s a pain.
So on track damp at first, feeling the car out… feels really good – soft but good. I start pushing a couple of really high powered Focus RS Mk2s that were out playing together – so I join in the fun. It doesn’t take long to overtake and pull away from them, where I then find that the traction control is playing me up, as it keeps kicking in. At one point I was dropping the gears going up and down the gearbox as the car just didn’t like the amount of grip the Cups and suspension were giving, so was constantly bogging the car down. This was ok if driving normally, but once you start to push the car, you have to turn the traction off or at least into MDM mode, where it allows you to have a certain amount of slip, but if the car feels like you are too far gone or really getting out of shape, it will gather the rear end up for you by cutting power and applying individual brakes. So with MDM mode enabled, now we are really flying another friend had a basically standard E46 M3 and it’s just hopeless against the modified E92. I meet up with the two Focus’s again and it’s not even sport now (the term shooting fish in a barrel springs to mind!) with the gap closed on them within two corners, and then I am on them and gone – this thing is a rocket-ship, still big, but damn fast! I take out various people and all of them are blown away by the car’s pace, the way the box changes gear and the sheer grip I am getting from the Cups and KWs…The APs are doing the job, but not 100 per cent satisfactory, but then I am having so much fun I’m not too bothered. I wrap the day up, put the standard wheels back on and set off ready for home with the biggest grin you can imagine. All the hard work getting the car to this level was finally paying off.
The next outing in the car was at a more familiar track for me, with Snetterton being my local circuit. This particular day a friend who owns an E46 M3 had just completed building a RWD Escort Cosworth with my old 500hp GT30 engine in it and as it weighed just 1200kg this was going to be fun against my 1480kg and 420hp – or to put it another way around 416hp per tonne versus 280hp per tonne – place your bets! As luck would have it was supposed to be snowing – is this lucky or not? I’m not too sure to be honest. I know I have a fantastic traction control system, but my friend who has a lot more rear-wheel-drive experience than me, has also got his E46 M3 with him (just in case the Cosworth breaks down).
It starts out without any snow, just wet and a bit slippery, but it doesn’t take me long to find him out on the track in the Escort and by the end of the back straight I have caught him, overtaken him and am long gone. The day pretty much goes on like this every time we cross paths. There weren’t many cars on track because of the weather, so I take the opportunity to explore the limits of grip in relative safety. Surprisingly it copes really well even when we go into a full blown blizzard and the marshals are still letting us out on track, you can’t help but have a little drift and the day was just getting better as my confidence in the car ramped up. Eventually my friend gave up fighting the limited traction in the Escort (probably fed up with being lapped by the “slower” BMW) and got his E46 out and we were now trying to drive as straight as we could in the snow (honest Mr Marshall!). With the childish antics out of the way I came home realizing I needed some good tuition in the car. The car was set-up super aggressively, especially for the wet and I knew that if I wanted to be fast I had to get some professional advice on what was going on with me and the car.
After reading up on some driver tuition there are various people out there and the guy I chose came very highly recommended and after reading a few articles from him, he certainly seemed to know what he was talking about – and perfect for my level of experience in a rear-wheel drive car anyway.
I decided that it was best to go back to Snetterton for my tuition, as I didn’t want the complication of learning a circuit at the same time as being taught how to handle the car on the limit. This time it’s dry, I know where I am going and the Cups are on. With the instructor in the car with me we start to push hard. MDM mode is engaged and he is showing me some very nice tips and tricks and some places to go a little deeper on the brakes or turn in a little earlier that transpired to him saying by the end of the day “we’re not hanging about” with a big grin. One piece of advice he imparted was for me not to jump off of the brakes and back on to the throttle so aggressively and that I should try and be a bit smoother. I have addressed this now, but at the time it was good to hear, as I think me braking too early and then jumping off the anchors to get back on the gas as quickly as possible was actually slowing me down. I probably still do it a little but I am certainly conscious of it now and am trying to change my driving style to his suggestions.
One thing I did start to notice now was the suspension could have done with being a little firmer on the front and the rear, as I noticed that the car felt a little floaty at high speed. I hadn’t noticed at Bedford, as it was my first time out with all the upgrades on the car and with the track being wet and snowing at the previous Snetterton trackday. With this all taken into consideration, I went away having learned a lot about the track, the car and myself.
Next month I will be getting into a bit more detail about the suspension geometry and there’s more track action from Cadwell Park this time as well as a sniff of the #Nurburgring …Stream item published successfully. Item will now be visible on your stream.

The story behind a glorious E92 M3 track car… it’s not all about power, as we find out. Phil Chapman took a leaf out of the Germans’ book when it came to transforming his E92 M3 into a track car capable of conquering the Nürburgring… Words: Simon Holmes. Photography: Chris Wallbank.
The German way of tuning is very different to the UK when it comes to the Nürburgring,” says Phil Chapman, owner of this E92 M3 track car. “Over there, they only really concentrate on three things; tyres, suspension and brakes. Power doesn’t even come into it.” What Phil preaches is true, the UK tuning industry does seem to suffer from chasing sky-high power figures above all else a lot of the time when, in fact, it should probably be concentrating on the more relevant criteria our German friends are well aware of. It’s a concept that often seems alien to us, though, to the point where some people in the UK have trouble believing what Phil tells them, but he very much practices what he preaches. “I was at a UK event and mentioned the car was capable of a 7 minute lap time at the ‘Ring with a virtually standard engine, and I was told that it wasn’t possible!” he tells us.
But Phil has done a 7min 30sec lap so safe to say that he is a capable hand behind the wheel. He’s no stranger to a fast car either, but the M3 is in an entirely different league and the story of how it all came to be started some years ago when he bought his first sports car. Logically, Phil decided that to get the best out of it he better learn how to drive it properly, so undertook some track driving tuition. Since then, he’s spent many more hours behind the wheel on track and it wasn’t long until he was making regular pilgrimages to the Mecca that is the Nürburgring. It was there he experienced a BMW for the first time and he was instantly sold on the brand after just a single passenger lap in an E46 M3 CSL.
Clearly it had quite an effect, as since then Phil has owned various respectable BMWs, including a couple of E46 M3 CSLs, a 1M Coupé, a 335d as well as a few X5s thrown in for good measure. He’s also owned plenty of high end, fast cars, but none seem to make the same connection with him as a BMW. “I went from the CSL to a Porsche, but realised it was the BMW I preferred,” he tells us. “There’s something I love about BMWs, all the ones I’ve had have been close to my heart, and I’ve had plenty of cars. Nothing grabs you the same way; they’re so beautifully balanced and you know they’re not going to bite you.”
With his BMW background, the transition to an E92 M3 might have seemed obvious, and it was, but not necessarily for the reasons you may be expecting, as he explains: “My second CSL had a slight gearbox problem. I spent 18 months trying to get it sorted out and my dealership was very good, but it just couldn’t get to the bottom of it. I was eventually told by someone at BMW head office that the CSL wasn’t designed for track use! I then fell out of love with the CSL, but I would have another tomorrow.”
The experience left a bitter taste and Phil ventured back to Porsche once again before realising he couldn’t than turn his back on the brand he loved. So he began looking at an E92 and capitalising on the credit crunch at the end of the last decade, he picked up this completely standard M3 with just 3000 miles on the clock back in 2008 for a very decent price.
Phil was instantly swayed by the DCT gearbox and the V8 powerplant. “How can you not like the engine? It sounds amazing!” he enthuses. But whilst the engine and gearbox were both huge steps forwards from the CSL he previously owned, Phil knew the chassis would need some dedication to unearth the best from it. “The chassis was amazing but it wasn’t at its full potential. I always like to tweak my cars and track was always where this was going to end up. Suspension and brakes were the first things to come, but when I started modifying it, not many other people were so it was hard to try and find parts to see if they worked. It was a bit of trial and error and, at first, it was me guessing, so I went through a few different brake and suspension setups.”
First on the agenda was to actually remove the factory fitted Electronic Damper Control. Whilst the system may be fine for road use, Phil quickly discovered it wasn’t quite so impressive round a track. “I took the EDC off straight away. With slick tyres fitted it freaked around a track, so I removed it and fitted a set of KW 2-way coilovers instead,” says Phil.
Following the German way of tuning, next came a set of better brakes, but back when the E92 was still new and unfamiliar with tuners, Phil had no choice but to have a custom brake kit made up using Lamborghini callipers with custom bells and rotors. “Nobody had done it before, so it cost a fortune. It was great and worked really well, but the brake pad choice was too limited and expensive. The callipers used eight pads so it was costing a lot to change them, and around the ‘Ring you change them regularly. So I’ve since swapped to an AP Racing kit just to get more pad choice and value.”
The KW coilovers have also since been replaced, this time with a Nitron three-way setup. These were specially spec’d for the car by German tuner Schirmer Race Engineering, which has had quite an impact on the car’s development. You may not have heard of Tom Schirmer before, but for those in the know, his black #BMW-E92 M3 track cars are legendary for being spectacularly fast and setting blistering track times. Phil first heard of Tom and his cars whilst at the ‘Ring, but aside from whispers, it was hard to actually track him down. Eventually he did though and an outing in Schirmer’s finely tuned E92 M3 demo car instantly confirmed he had found the man capable of developing his car to the next stage. “He’s a hard guy to find but once I went out in his demo car, that was it, within three minutes I knew I had found the right person,” Phil tells us. That same demo car has recently done a scorching 6min 58sec lap time at the ‘Ring, in case you’re wondering just how fast it is…
Phil ordered one of everything from the Schirmer catalogue, and after leaving the car in Germany, he picked it up a month later with huge, instant results. “It’s just phenomenal. Around a track the car is mind blowing,” reveals Phil. ”When you feel it all come together, it’s hard to believe how good it is. The car feels so planted it’s hard to explain without taking you out on a passenger lap. Its main advantage is that it can carry so much corner speed. It’s set up to do that and it’s the reason it’s so fast without huge amounts of power. It wouldn’t do so well at another track but I love the way it drives.”
Schirmer’s carefully selected chassis modifications extended to include a Drexler derived LSD and the wider #BBS split-rims, measuring 10.5-inches at the front and 11-inches at the rear. Whilst both Team Schirmer and Phil maintain huge amounts of power isn’t important, there have been some mild tweaks under the bonnet as well. A full Akrapovic exhaust system replaces the original items and it’s complemented by a Schirmer designed large capacity carbon fibre air box, #Schrick cams and a remap, which sees power around the 470hp mark. A notable improvement, but hardly huge amounts either. Aside from what’s lurking underneath, it’s hard to ignore the fact the car has more than an air of function over form outside as well, in a stealth kind of way. The various aero upgrades aren’t there for looks as most are borrowed from an M3 GT4 and GTS so are designed to do a job. The menacing colour combination is no mistake either as although the car is track orientated, Phil always keeps in mind the overall look of things: “My job is branding so the look is everything and detail is important. I like the way it drives but from a parts point of view I love the look of the wheels and the wing mirrors.”
Despite the looks and huge potential on track, the M3 is still road legal and was driven regularly. But it’s now got to the point where Phil leaves the car at the Nürburgring to make things easier as he has other, better-suited cars to travel to Germany in and he visits the ‘Ring once a month during the summer season. Of course, you won’t be surprised to learn that Phil readily admits he’s gone further with the M3 than he ever intended to and the car is virtually unsellable now, but only because he’s enjoyed it so much over the years he’s had it: “I’ve had so many good memories and experiences in it it’s part of the family, the car’s value doesn’t really come into it anymore. It never misses a beat and it’s always been absolutely faultless, even when I’m pushing the car hard round the track all day, from 8am until sunset.”
Despite the well-honed modifications and hugely impressive lap times, for now, the M3 is actually going to be put to use as a kind of working mule car for Phil’s next development; an all new car. Plans are afoot to take Phil’s track driving to the next level, which means he will be competing in a Brit Car competition race next year. For that, he’s building an all-new E90 3 Series with a planned 600hp on-tap and a curb weight around the 1100kg mark. The #BMW-M3 will be using the proposed racing engine first of all and not one to do things by halves, he’s looking at a Schirmer developed 4.4-litre conversion with parts shared from the M3 GTS in order to keep it strictly naturally aspirated. “The supercharged cars don’t really work at the ‘Ring,” reveals Phil. “They get too hot.” Sometimes it’s not all about the power…
