Show original supplier description
The Paragon Performance Track Performance Rear Big Brake Kit provides superior braking performance for track-day enthusiasts. It features CNC-machined PA025 4-piston calipers constructed from 6061-T6 aluminum, paired with 355x32mm fully-floating 2-piece rotors made from CM-250 high carbon alloy cast iron. The calipers are finished with a hard anodized coating for extreme heat resistance and feature titanium nitride-coated pistons for smooth travel and longevity. The assembly includes Goodridge stainless steel braided brake lines, caliper mounting brackets, and P3 semi-metallic street/track brake pads. Installation requires verifying wheel fitment prior to ordering, as this kit is custom-made to order and cannot be returned due to fitment issues. These 355mm rotors generally require 18-inch or larger wheels, though clearance depends on specific wheel design. Users must download and use the provided wheel fitment template to ensure proper clearance before purchase.
