PARAGON 4-Piston Rear Big Brake Kit – BMW M2 (G87) / M3 (G80) / M4 (G82/G83)
This Paragon Track Performance rear big brake kit is a complete, pre-assembled rear axle upgrade for the BMW M2 (G87), M3 (G80) and M4 (G82/G83). Paragon PA025 4-piston calipers and fully floating 2-piece rotors with 48 directional vanes handle high thermal loads, running up to 30% cooler than OEM for consistent rear braking lap after lap.
The kit is offered with 355 x 32mm or 380 x 32mm rotors, a choice of Paragon P2, P3, R5 or R7 pad compounds, and hard anodised or ENP (electroless nickel plated) caliper finishes.
Note: This kit eliminates the OEM E-brake / parking brake function. Piston sizing is matched to work with the OEM ABS and master cylinder. Installation by a professional is recommended.
