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.

  • Two Part Durable Powdercoated Calipers (choose color in options)

Innovative caliper with class leading stopping power!

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.

These brakes perform and operate best at 6-800 psi brake pressure under normal braking pressure. The proper master cylinder and pedal ratio is essential to proper performance. Don't know how to calculate this? Give our team a call, we are happy to help! (800) 878-9274

Great quality wire for any automotive or 12 volt wiring
Size: 16 AWG-100 ft
This GS Power 16 gauge wire is excellent quality for any automotive wiring project. The copper is true OFC pure copper, not copper clad aluminum. It’s flexible, easy to route, and holds up well without the insulation feeling cheap or brittle. I have used it for automotive accessory wiring and some 12V equipment projects and it handled everything perfectly. The wire pulls cleanly, solders well, and the insulation thickness gives it a durable feel without being overly bulky. If you need dependable wire for automotive, marine, RV, audio, or general electrical projects, this is a great buy. I would absolutely purchase it again.

Not the sorry copper coated aluminum.
Size: 16 AWG-100 ft
The wire is 16 gauge plenty big for my system. Heck, the wires supplied with my stereo, copomonet speakers, and amplifiers are about 20 or 24 gauge. I'm quite sure the wire will be more than suffeceint. I, m installing a mono sub amplifier a four-way amplifier to the sub amp outputs and the front of lines of the stereo. I'm gonna be pushing 20 speakers all except the sub woofer only pushing 100 watts a channel and the sub will push 150 watts. That makes 21 altogether. Not much just good clean sound. I've been working on the project going on 5 years now. Been bargain hunting, besides the work I've only got about $650 in the project. Can't wait to get it completed here around the end of July. Hopefully, it will sound great didn't want to pay anyone. Seen too many "professional" jobs that were subpar. I've seen some nightmares. Figured if l did the job then who could I blame at least I can only blame myself and didn't pay $1,000 for it. 😁🤔
