Big Brake Kits (BBK) — Front & Rear
A big brake kit replaces your factory caliper, bracket and rotor with a larger multi-piston fixed-caliper system on a 2-piece floating rotor. Pad area, thermal mass and clamping force all increase — transforming heat handling and pedal feel for track, time-attack, endurance, autocross or aggressive street use.

Wheel Clearance & Pad Selection
BBK installations require wheel fitment validation — most kits need 18-inch or 19-inch wheels minimum, sometimes with spacers. Pad selection is critical: use street pads (Hawk HPS, EBC Yellowstuff) for daily, race pads (Pagid RSL, Endless ME20, Project Mu HC800) for track. Stainless braided lines, high-temp fluid (Castrol SRF, Motul RBF 660) and ducting complete the system.
