Endless Racing MONO4 Rear Big Brake Kit with 345mm 3-Piece Rotors for F40 Ferrari [5202253]
The Endless Racing MONO4 is a complete F40 rear big brake kit for the 1990-1992 Ferrari , pairing forged monobloc four-piston calipers with 345mm x 32mm three-piece slit rotors, performance pads, caliper mounting brackets, and brake lines for the rear axle. Endless machines the Racing MONO4 from a single forged piece of aluminum, so there is no bolted joint to flex under pressure, and the finished caliper weighs 2,100g. 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 racing anodize caliper finish.
Features
- Forged monobloc Endless Racing MONO4 calipers; a one-piece body with no bolted joint to flex under pressure
- Slit rotor face continuously refreshes the pad surface and vents gas without the cracking risk of cross-drilled discs

- Direct bolt-on installation on the F40 with the included mounting brackets
- Machined to Endless production standards with surface accuracy held to 1/1000mm

- This kit services the rear axle only; Endless offers matching front systems.
- Sold as a complete rear brake kit (one axle, both corners).
Frequently Asked Questions
- Will this F40 rear big brake kit clear my wheels? Clearance depends on wheel design, not just diameter. This kit runs 345mm x 32mm rotors and the Endless Racing MONO4 caliper is sized for wheels from 15 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 5202253 kit? The kit includes two Endless Racing MONO4 calipers, a brake pad set, two caliper mounting brackets, two 345mm x 32mm three-piece rotors, and two brake lines. It is a complete rear-axle system for the F40 Ferrari under one part number.
- Can I run this rear kit with the factory front brakes? The Endless Racing MONO4 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 MONO4 calipers? The Endless Racing MONO4 runs 18mm-thick pads in the RCP146 / RCP153 shapes. Endless supports its TR, MX72, MX72 Plus compounds in this caliper, so the same f40 rear big brake kit covers street driving through track use on a pad change.
- Is this kit a direct bolt-on? Yes. Part number 5202253 ships with mounting brackets and brake lines for the 1990-1992 Ferrari 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 5202253 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.
