    AMERICAN RESPONSE

    As the E46 M3 CSL never made it to the #USA , #BMW enthusiasts set about building their own, like this tasty pair. America was cruelly robbed of the E46 M3 CSL, so the response of Stateside modifiers has been to create their own with even more muscle. Words: Iain Curry. Photos: Marco Svizzero.

    It’s easy to get jealous of Americans. They produce money-spinning movies and music loved the world over; they seemingly control the world markets, the internet and practically every satellite in the sky; and if civilisation goes down the plughole, they keep enough gold locked away to hold two fingers up to the rest of us.

    But if you want true envy, check out how cheaply Americans can buy a new M3, M5 or Porsche 911, then see how little it costs them to fuel them so they can enjoy playtime for far less coin than the rest of the world.

    But occasionally, Europe gets its own back. Prime example is the E46 M3 CSL: a car so raw, pure and driver-focused that it became an instant classic on its 2003 release, and one the enthusiasts went all wobbly over. But not the Americans. They got bitter, frustrated and angry over it as the things just weren’t allowed Stateside due to environmental and safety reasons. There were 1400 examples built, and 1400 didn’t find their way to American showrooms.

    So while the non-CSL E46 M3 is almost laughably common on American roads, you’re not about to see a CSL barking its way along canyon roads or buzzing city streets. You may spy something close though. Deny a market like America a car it badly wants and, much like banning a movie, it makes the thing so much more desirable and some will stop at nothing to get it. Pictured here are two Californian E46 M3 CSL replicas, which in many regards are as close to the real thing as possible. Certainly substantial sums of cash have been parted with in their builds, but that’s the price needed to pay proper homage to the ultimate road-going E46 M3.

    It’s a price Adam Cook of Citrus Heights in North California paid to create his Steel grey E46 M3 CSL replica. We caught up with him and photographed his CSL replica alongside another built by Andrei Afanasiev – a fellow www.m3forum.net user from California’s Bay Area. Together they are a formidable pairing, with Adam’s looking the more genuine with its CSL-esque paint (originals only came in Silver grey and black Sapphire), even though Andrei’s M3 CS colour is a beautiful shade.

    “BMW should have brought the CSL to the US,” Adam said. “There should be a standard that works for both US and Europe for safety and the environment so we can both get the same cars. An example is my other car, a 1M Coupé. They brought that to the US and it sold out fast.” Regardless, Adam got busy building what BMW didn’t provide, and is convinced he’s created something at least the match of a true CSL. “My setup makes more than a stock CSL,” he said. “ I have a better exhaust, pullies and a better software tune.”



    Adam bought his E46 M3 brand-new from his BMW dealer in 2002, and was already no stranger to the marque. As well as his 1M he’s owned an E46 330i, E39 530i and an E90 330i. After a few months of M3 ownership on went a K&N panel filter to get the ball rolling, and since then he’s barely drawn breath. To see the inventory of all the previous parts he’s fitted to the M3 as well as what’s currently there – and the wellrecorded cost of everything – is quite frightening. “To build a replica CSL is fairly easy once you get hold of OE parts, and it helps to have more cash than brains and keep throwing money at it,” he said.

    Adam wanted to make his car as much of an OE CSL as possible, but also improve on parts where he thought necessary. “My modifying philosophy was if I owned a real CSL what would I change on it?” he said. “I think the likes of headers, brakes, exhaust and suspension could all be improved.”

    Starting with the body, Adam has upgraded his M3 with an OE CSL front bumper, lights, side grills, bootlid, carbon fibre rear diffuser and emblems. And impressively, as one of the CSL’s signature elements, he’s managed to add an OE carbon fibre CSL roof. “I got most of the OE CSL parts from a US importer which has sadly recently gone out of business, while the rest I got from a European source,” he said. “I’m glad I got them when I did as CSL parts are now no longer being made.”

    Adam said most of the CSL parts are direct replacements on a standard M3, although minor modifying included rerunning wires on occasion. The roof was a different matter though: “The roof is genuine OE BMW, and its install was mostly time and patience,” Adam said. “Eighty-six spot welds needed removing and then the surface was cleaned. The OE roof fitted perfectly so no major work was needed other than adding the centre brace: if you remove the old roof properly there is no extra welding needed other than for the centre brace.”

    The interior also mimics a CSL’s with an OE CSL centre console added, something Adam said was basically plug and play. There are online DIY tutorials on forums for the fitting, requiring a bit of time and rerunning window switch wires. Also on are a CSL handbrake gaiter, door trims, handles and door sills, while the rear seat has been removed in the style of the M3 CSL concept model. Recaro Profi XL seats are now up front, which look superb but Adam said they’re not great on long journeys. But ridding his M3 of power front seats and the rear bench has saved a lot of weight. As for CSL-ing the 3.2-litre six-cylinder, parts availability proved a headache. Adam originally fitted a GruppeM intake, but was intent on finding a true CSL air box. “Finding a CSL air box and cam was hard as there are not many in the wild,” he said.

    “The first cam I got was broken in shipping and took nine months to get a replace.” Other OE CSL engine parts include the rocker arms, exhaust valves and the head gasket. Adam has enhanced things further with the likes of Supertech Performance dual valve springs, Rogue Engineering power pulleys, some trick cooling and an extensive exhaust system upgrade. Rounded off with OE M3 CSL software and an Evolve ECU tune Alpha-N Stage 3, these enhancements have convinced Adam he has a genuine CSL-beater on his hands.

    The car’s six-speed SMG auto has also been given the CSL treatment with its software flash, while Adam uses a Turner Motorsport 3.91 differential and the company’s rear subframe reinforcement. A CSL 14.5:1 steering rack is also employed for the genuine feel, while TC Kline Racing adjustable coilovers and camber/caster plates, Eibach anti-roll bars and Ground Control rear lower control arms are part of a suite of underbody enhancements to push this M3 into CSL territory and beyond.

    The genuine look was required under the arches, and Adam sourced genuine 19” CSL rims and shod them in Michelin Pilot Super Sport tyres, rather than the ‘widow maker’ Michelin Cup rubber that made true CSLs so likely to switch ends in the wet. Behind these wheels are mighty StopTech 355mm discs all-round, clamped by four-pots finished in yellow paint. To look upon the car is to believe it’s a true CSL, and one that’s been enhanced impressively further.

    Andrei’s car is based on an M3 CS and it too has an impressive spec sheet. Under the bonnet the S54 has been given an OE CSL carbon air box running Evolve Alpha N software and VAC Ultra Light 2 pulleys. He’s also removed the sound deadening to enjoy more of that intoxicating induction howl. Strapped to the Dinan strut brace are the remote reservoirs for the Moton Club Sport dampers and the chassis has been further upgraded with an AC Schnitzer rear anti-roll bar, Poweflex bushes throughout and a TMS subframe reinforcement kit, while for the exhaust system, he opted for an Eisenmann Section 2 and Meisterschaft Ti system.

    Parked side-by-side, the two E46s look as though they belong at the M3 CSL top table. And so they should with the huge amount of time and money involved, including the relentless hunt for OE CSL parts for the builds. Much like true CSLs, they have that look about them that makes you want to grab the keys and be left alone on a winding stretch of open road for a few hours.

    “I prefer back roads to the track,” Adam said, “and am one of the few people in North California who organises meets and drives. I have a website called www.raddrives.com that lists my favourite drive routes, and one of the best is Valcano which is perfect for the CSL. It’s a joy to drive because you feel the connection to the car and the road, and as the last of the high revving straight-six motors you can feel that passion the M guys put into the car. Cars now are faster, but some of the soul has been lost for progress.”

    Adam wouldn’t dissuade anyone from building their own CSL replica, but he warned that OE parts are a pain to find as there are few parts and plenty of people after them. It’s not cheap either, so despite the rising value of genuine CSLs, if your country was lucky enough to sell them – unlike in America – it may be best to just buy a real one.
