Specifications — BKIN300-653SO
Product details
This six-piston rear kit fits the 2014-2018 Infiniti Q70 RWD with 15 in slotted rotors. Supercomp calipers mount on two-piece rotors, a setup suited to a sport sedan that sees both road and track time, and it moves the rear axle up to 15 in rotors for owners who want more rotor size at the back.
Included are the calipers for this application, two-piece slotted rotors, SC5 street brake pads, stainless-steel braided brake lines, and caliper mounting brackets with hardware. The floating two-piece rotor design is described as aiming for even pad contact.
Check the year, make and model checker before buying, and keep part number BKIN300-653SO in mind when comparing rear kits. Factory master cylinder and ABS stay in use. With 15 in rotors, confirm wheel clearance against the template, barrel and spokes.
Supported features
One-piece construction from a solid billet of aerospace-quality aluminum rather than cast or welded, for even thickness and strength across the caliper block.
The outer section shifts slightly as needed for better self-centering in the caliper, lowering brake drag and boosting performance through more even application.
Calipers, floating brake discs, SC5 street pads, owner's manual, and all required hardware come standard.
CNC-machined carbon steel brackets let the larger 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.
DOT-compliant stainless braided lines stop expansion under pressure for quicker response and a firmer pedal than stock rubber lines.
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.
