TBM XS3 Rear Extreme Street Brake Kit (012-0312-1) - 2009-2015 Cadillac CTS-V
Upgrade the rear braking performance of your 2009-2015 Cadillac CTS-V with the TBM Brakes XS3 Rear Extreme Street Brake Kit. Developed from more than 30 years of racing experience, the XS3 Series bridges the gap between lightweight race brake systems and the larger, heavier street performance packages commonly found on modern high-performance vehicles. With compact 12.19-inch slotted and vented rotors, billet four-piston calipers, and proven Hawk Performance HPS pads, this kit delivers strong stopping capability and responsive pedal feel while maintaining compatibility with many smaller-diameter wheels.
The race-inspired XS3 calipers are machined from solid 6061 aluminum and use four 1.375-inch pistons per caliper for excellent clamping force and controlled rear braking performance. TBM's internal crossflow design eliminates external transfer tubes while helping distribute hydraulic pressure evenly across the pistons. Billet CNC-machined 304 stainless steel pistons, black anodized brackets and hats, dark zinc-plated rotors, and quality 12-point hardware complete a durable and performance-focused package for serious street and track-oriented builds.

Caliper Design
The XS3 Extreme Street caliper incorporates engineering developed through TBM's racing brake programs into an all-billet package designed for demanding street use. Its rigid bridge structure helps minimize caliper flex, while four 1.375-inch stainless steel pistons provide consistent clamping force and controlled braking torque. The internal crossflow fluid path promotes smooth operation and even piston pressure without exposed external crossover tubes.
Rotor Design
The included 12.19-inch cast rotors feature slotted and vented construction to balance stopping power, heat management, durability, weight, and appearance. Their compact diameter helps maintain compatibility with many factory and aftermarket wheels measuring 15 inches or larger. A dark zinc finish provides additional corrosion protection before installation and helps protect rotor areas that are not swept by the brake pads.
Brake Pads
This kit includes Hawk Performance HPS brake pads featuring a Ferro-Carbon friction compound. The HPS material provides a strong balance of stopping capability, manageable brake dust, and reduced noise compared to more aggressive race-oriented compounds.
Billet Brake Hats
TBM's billet aluminum brake hats reduce unnecessary rotating mass by eliminating the heavier steel center section found in traditional one-piece rotors. Their stepped mounting design also allows minor axle offset adjustment to assist with proper brake alignment during installation.
