General Setup Guidelines, Read Before Installing: Click Here

Built with over 30 years of heritage in racing, TBM Brakes introduces its first purpose built street performance brake kit, the XS3 series featuring a 12.19" vented rotor. Designed to be the bridge between our lightweight single thickness steel racing brakes and the large diameter rotor street performance brakes commonly seen in late model vehicles while providing incredible stopping power.

This brake kit was specifically designed to give the ability to run smaller diameter / factory size wheels without sacrificing braking potential. We even found this kit able to work with many steel factory 15" wheels as well as drag racing wheels.

The XS3 Extreme Street caliper is an innovative new design built off principles and engineering from our line of racing calipers. This all billet caliper provides ultimate in strength for a better feel and performance. With a stronger bridge strength and more rigid caliper than most aftermarket aluminum calipers we are able to provide larger clamping force to achieve the brake torque to stop your vehicle. Choose your choice of color in powdercoat. 

12.19" Slotted & Vented Rotor Balances Weight and Durability

Our cast vented and slotted 12.19" rotor was designed to balance weight, stopping power, cooling ability, and looks while keeping the ability to package with most factory and aftermarket wheels 15" and larger. These rotors are black plated to protect against rusting / corrosion and look good before first use and beyond.

Built in Wheel Speed Sensor Mounting Solutions

Proven Brake Pad Technology:

Utilizing the Hawk Performance HPS Ferro Carbon compound, this brake pad strikes the perfect balance of stopping potential without bringing noisy brake pads and large amounts of brake dust into play.

Billet TBM Brake Hubs

Our Billet Hubs save valuable weight while offering a rigid mounting solution for your XS3 rotors! These hubs come with and utilize Timken bearings for ultimate durability. With a built in mounting option for a speed sensor wheel, this 

Note: We do not recommend the use of silicone based brake fluid with these calipers. Only use approved DOT3, DOT4, or DOT 5.1 brake fluid. We recommend using TBM Extreme 6 Fluid for best results.
