About the BMW E46 M3 

The third in BMW’s high-performance coupes developed by M GmbH as the successor to the love-it-or-hate-it E36 M3, the E46 M3 brought 338 bhp and individual throttle bodies to America, unlike it’s neutered predecessor. With a high-strung S54 inline-six under the hood, a manual 6-speed transmission, LSD rear end, and competent suspension, the E46 M3 is a great platform out of the box. That isn’t to say it can’t be improved, however, which is exactly what we aim to do. Below, we’re going to show you everything we plan to upgrade on the M3 before it finds its way to a lucky new owner who will surely enjoy our tasteful upgrades provided by our partners to help bring out the full potential of this incredible machine. 


The brakes are receiving a serious upgrade from StopTech in the form of their top-of-the-line nickel-plated calipers on their front and rear big brake trophy kit. New 355mm front rotors, rear rotors, 6-piston front calipers, 4-piston rear calipers, and braided steel lines also from StopTech will help seriously improve the braking performance, pedal feel, and help reign in all the power we hope to add to our M3.


The suspension we chose for the M3 includes extensive upgrades to the whole system. Turner Motorsport front and rear Monoball upgrades will eliminate deflection and improve the turn-in response of the M3, especially paired with the Bilstein upgraded sway bars, bushings, and fully adjustable coilovers. Our own ECS Diff Bushings will further help eliminate deflection, while the Turner Motorsport front and rear subframe reinforcements will prevent any stress from causing damage to the notoriously weak factory mounting points. These upgrades will ensure whomever owns the M3 will have peace of mind that the subframes won’t suffer from the cracking problems normally seen on these cars after hard driving. 


With bigger brakes and beefier suspension, the M3 can receive engine upgrades to increase power and performance. The Turner Motorsport CSL style intake manifold, Turner tune, and Turner power pulleys will help seriously bolster the already impressive performance capabilities of the S54, giving the powerful inline-six a hearty boost in fun when you press the throttle. Of course, a few other key modifications like the ECS braided steel VANOS line, water connecting line, and Turner IAT relocation kit will offer improvements over those wearable factory versions and ensure intake temperature readings stay accurate for better performance.


Of course, upgraded suspension and engine performance mean the drivetrain can’t be ignored. A DKM clutch and flywheel setup will help put all the power to the ground while the Turner Motorsport Short Shift Kit, Turner Shift Knob, ECS Braided Steel Shift Line, and Teflon Shifter Bushing will give the driver a seriously connected feeling and incredibly engaging driving experience.


The E46 M3 looks subtly aggressive with its reserved body lines and rounded hips, but with some simple changes, it can take on an incredibly mean appearance. The Turner Motorsport Carbon Fiber Rear Diffuser, and Rear Spoiler will give a much needed motorsport-inspired theme to the high-performance BMW and match the car’s abilities with a sleek new look. Additionally, the Turner Motorsport Skid Plate will help prevent the lowered ride height from causing any damage to the undercarriage while also retaining the factory aerodynamics, which means this car can be enjoyed without worry that its expensive underbody bits could be damaged by nasty bits of road or other hazards. 


For the noisemaker, SuperSprint is providing their hand-built stainless steel performance exhaust that will open up the pipes and let the glorious sound of the S54 sing through highly engineered exhaust designed to offer both power gains and an exceptional noise. 


The black leather interior looks incredible and carries a similar theme BMW has held for years, which looks fantastic, but E46s are not known for their interior quality. We’re going to address all of that with new trim pieces, pedals, a Carbon Fiber steering wheel trim set from Karbonius, new Bremmen Head Unit, and make sure the liners everywhere are in perfect shape. Brey Krause will provide harness bars, while Schroth belts will keep the driver pinned in the seat for any hard-driving they might be inclined to enjoy. We want to ensure the new owner has a showroom-quality interior to enjoy that matches the attention to detail the rest of the car will receive, so no corners will be cut here!


In the restorative departments, we will tackle nearly everything needed to bring the E46 M3 back up to factory condition anywhere that isn’t receiving performance upgrades. LIQUI MOLY and HENGST are brining their expertise to handle the lubrication and filtration needs for oil, while Meyle suspension parts will help bring back the incredible handling feel the M3 had when new. Lastly, to tackle those BMW cooling woes, CSF is giving us their high-quality aluminum radiator to help combat those temperature issues known to plague BMWs of this era.

Nearly every aspect of the car will be tweaked and improved over the coming weeks with help from all the fantastic partners we mentioned.
