02 / THE KIT

Slimline at a glance.

Aggressive wheel fitment leaves little room between the caliper and the back of the wheel, so most big brake kits will not fit. The Slimline caliper is based on the OEM single-side piston caliper thickness, letting you upgrade to a big brake kit and keep most factory wheels or wheels with very limited clearance.

Kits are sold per axle. Each front or rear kit is listed as its own part number for your vehicle, with cross-drilled or slotted rotors.

Technical details

Built around your application.

Two-Piece Rotors

Extremely lightweight two-piece rotors — commonly up to 50% lighter than OEM rotors of the same size.

Everything You Need

Calipers, floating brake discs, SC5 street pads, owner's manual, and all required hardware come standard.

Carbon Steel Caliper Brackets

CNC-machined carbon steel brackets let the calipers bolt to the OEM caliper bracket location.

Slotted or Cross-Drilled Rotors

Cross-drilled rotors run cooler for daily-driven vehicles; slotted rotors are recommended for more track use.

Custom Caliper Options

Standard painted orange, red, black, and yellow; premium high-polish silver, gold, and titanium; glassy and hard-anodized finishes; over 20,000 custom colors on request.

Choices when you order

Confirm the exact part for your vehicle.

Rotor style

Cross-drilled rotors run cooler and are recommended for daily-driven cars; slotted rotors are recommended for cars that see more track use. Each style is its own part number for your vehicle.

Caliper finish

Painted KSport orange, race red, caution yellow or jet black at no extra charge; premium high-polish, glassy and hard-anodized finishes cost extra.

Pads and center bells

Street pads are standard; race pads and titanium or twin-colour anodized center bells are optional upgrades.

Front, rear or both

Kits are sold per axle and work with the OEM master cylinder and ABS. Fit both axles for the most balanced result; front-only is fine, rear-only is not recommended.
