Endless M4 / S2 Front & Rear Big Brake Kit with 316mm Rotors for ZC6 Subaru BRZ *PCD100 [1913166-316]
The Endless M4 / S2 is a complete ZC6 big brake kit for the 2013-2020 Subaru BRZ *PCD100, pairing four-piston M4 front calipers and two-piston S2 rear calipers with 316mm slit rotors, performance pads, caliper mounting brackets, and brake lines for the front and rear axles. Both axles get matched Endless calipers so bias, pedal feel, and pad character stay consistent front to rear. 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 front and rear kit in the Endless blue anodize caliper finish.

- Matched Endless M4 front and S2 rear calipers keep brake bias and pedal feel consistent across both axles

- Direct bolt-on installation on the ZC6 with the included mounting brackets
- Machined to Endless production standards with surface accuracy held to 1/1000mm

Notes
- Verify wheel clearance before ordering; Endless publishes wheel clearance diagrams and Bulletproof Automotive will confirm fitment against your wheel specs.
- Bed the pads in dry conditions; bedding in rain prevents the pads from reaching full performance.
- This kit services both axles as a matched system.
- Sold as a complete front and rear brake system (all four corners).
Frequently Asked Questions
- Will this ZC6 big brake kit clear my wheels? Clearance depends on wheel design, not just diameter. This kit runs 316mm rotors. 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 1913166-316 kit? The kit includes Endless M4 front calipers, S2 rear calipers, brake pad sets, mounting brackets, rotors for both axles, and brake lines. It is a complete front and rear system for the ZC6 Subaru BRZ *PCD100 under one part number.
- Why choose a front and rear kit over a front-only upgrade? A matched front and rear system like this Endless M4 / S2 kit keeps brake bias close to the engineered balance as outright grip rises. Front-only upgrades work well for street use, but dual-axle kits keep the car neutral under hard, repeated braking on circuit.
- What pad compounds work with the Endless M4 / S2 calipers? Endless supports its street-through-track pad compound range, including MX72 and MX72 Plus, across these calipers, so the same zc6 big brake kit covers daily driving and circuit days on a pad change. Contact Bulletproof Automotive for the current compound lineup.
- Is this kit a direct bolt-on? Yes. Part number 1913166-316 ships with mounting brackets and brake lines for the 2013-2020 Subaru BRZ *PCD100, 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 1913166-316 is sold as one complete front and rear brake system covering all four corners: calipers, rotors, pads, brackets, and lines, priced and shipped as a single system.
