Product details
A 13.8 in (350 mm) slotted two-piece rotor is the defining size on this Slimline front kit for the 1997-2001 Mitsubishi Mirage. Three-piston one-piece billet aluminum calipers grip each rotor, and aluminum center bells come with the set. SC5 street brake pads, stainless braided lines and CNC-machined caliper brackets with hardware complete the box.
The OEM handbrake will not function once this kit is fitted, so decide on your parking-brake plan before the car is driven on it. Slotted rotors are the track-leaning option in this Slimline range for owners who push harder on track days.
No wheel clearance figure is stated for the 13.8 in set, so measure your wheels against the rotor before ordering. Confirm fitment with the year, make and model checker before buying. Keep the handbrake note in mind when you plan the installation work.
Supported features
A single-side piston caliper that keeps the styling of the multi-piston calipers while fitting behind wheels with limited clearance.
Extremely lightweight two-piece rotors — commonly up to 50% lighter than OEM rotors of the same size.
Calipers, floating brake discs, SC5 street pads, owner's manual, and all required hardware come standard.
CNC-machined carbon steel brackets let the calipers bolt to the OEM caliper bracket location.
Cross-drilled rotors run cooler for daily-driven vehicles; slotted rotors are recommended for more track use.
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.

Installation
Bolt-on installation with the supplied brackets; no vehicle modification on most applications. After fitting, bed the pads in: on a clear road, ten light-to-medium stops from 30–45 mph, three seconds each, at least a quarter mile apart. Some noise before the brakes warm up is normal for big brake kits.
Brake system support and bed-in procedureWarranty & service
12-month limited warranty to the original purchaser against defects in materials and workmanship. Racing use, exterior finish and improperly installed or modified parts are not covered; keep your original invoice for any claim. Small surface cracks on cross-drilled rotors are normal wear and not a defect. Replacement pads, rotors, lines and hardware are sold individually.
