Endless Racing BIG4 Rear Big Brake Kit with 355mm 3-Piece Rotors for E90 BMW 330i/335i [4202212]
The Endless Racing BIG4 is a complete E90 rear big brake kit for the 2005-2011 BMW 330i/335i, pairing forged two-piece four-piston calipers with 355mm x 32mm three-piece slit rotors, performance pads, caliper mounting brackets, and brake lines for the rear axle. The Racing BIG4 body is a forged two-piece design at 3,486g per caliper with 27mm and 32mm piston sizing that loads the pad evenly. The rotors carry the Endless slit face that keeps the pad surface clean and friction stable as heat builds. Every component is designed and manufactured in Japan by Endless. Supplied as a complete rear-axle kit in the Endless blue anodize caliper finish.
Features
- Forged Endless Racing BIG4 calipers with paired piston sizing for even pad pressure and a firm, consistent pedal

- Direct bolt-on installation on the E90 with the included mounting brackets

Frequently Asked Questions
- Will this E90 rear big brake kit clear my wheels? Clearance depends on wheel design, not just diameter. This kit runs 355mm x 32mm rotors and the Endless Racing BIG4 caliper is sized for wheels from 17 inches. Endless publishes wheel clearance data for its kits; contact Bulletproof Automotive with your wheel specs before ordering and we will confirm fitment.
- What is included in the Endless 4202212 kit? The kit includes two Endless Racing BIG4 calipers, a brake pad set, two caliper mounting brackets, two 355mm x 32mm three-piece rotors, and two brake lines. It is a complete rear-axle system for the E90 BMW 330i/335i under one part number.
- Can I run this rear kit with the factory front brakes? The Endless Racing BIG4 rear kit installs independently, and Endless offers matching front systems for most applications. Most builds upgrade the front axle first or together with the rear, since the front carries the majority of braking load. Contact Bulletproof Automotive for a matched front and rear setup.
- What pad compounds work with the Endless Racing BIG4 calipers? The Endless Racing BIG4 runs 18mm-thick pads in the RCP052 shapes. Endless supports its SSM, TR, MX72, MX72 Plus compounds in this caliper, so the same e90 rear big brake kit covers street driving through track use on a pad change.
- Is this kit a direct bolt-on? Yes. Part number 4202212 ships with mounting brackets and brake lines for the 2005-2011 BMW 330i/335i rear axle, so the kit bolts on without fabrication. Bed the pads in dry conditions after installation to reach full performance.
- How is the kit sold? Part number 4202212 is sold as one complete rear brake kit covering both rear corners: calipers, rotors, pads, brackets, and lines, priced and shipped as a single system.
