BMW 3-Series (E46) Fitment Guide
The E46 chassis is widely celebrated as one of the most balanced driver's cars ever built. However, whether you are running a fast-road M3, a dedicated track car, or a boosted build, modern grip levels quickly expose the thermal limits of the factory brakes. These Alcon Big Brake Kits shed unsprung weight while massively increasing thermal capacity, ensuring fade-free performance lap after lap.
Confirmed Fitment:
- BMW 3-Series E46 (Inc. M3)
Performance Tiers:
- Street Performance (CAR97 / CAR99): Engineered for spirited daily driving. These calipers feature standard dust boots to protect against road grime. Note: CAR97 is strictly engineered for 32mm rotor configurations.
- Street/Track Performance (Car49 TA4+ / CAR89 TA6 / CAR89 ENP): The ultimate hybrid setup. The nimble Car49 TA4+ is perfect for lightweight 343mm setups, while the CAR89 variants handle larger 355mm+ rotors. The ENP version features a premium Electroless Nickel Plating for superior heat radiation.
- Track Performance (CRB343 / CR6380 / CAR89): Dedicated motorsport braking without dust boots. Strictly for competition use to ensure maximum clamping force without fade. Note: CR6380 is exclusively compatible with 355x32mm and 380x32mm rotors, while the CRB343 is optimized for 343mm setups.

The team took a mostly broken car after some work done elsewhere, and have systematically made it reliable and fast for a fair price. The staff are invested in the work they do which also makes a big difference.
