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. 

Features:

  • Race Inspired XS3 4 Piston Caliper
  • Billet housings machined from solid 6061 Aluminum Alloy
  • Crossflow caliper design eliminates external tubes, and promotes equal pressure to piston distribution 
  • (4) 1.75" OD pistons per caliper deliver exceptional stopping power and pedal feedback
  • Two Part Durable Powdercoated Calipers (choose color in options)
    • Race Red
    • Satin Blue Metallic
    • Velocity Yellow
    • Gunmetal Gray
    • Onyx Black
  • Black Anodized Brackets, Hats
  • Dark Zinc Plated rotors offer corrosion resistance before and after installation (please note rotor color can vary due to process)
  • Billet CNC Machined 304 Stainless Steel Pistons
  • Unique Cross flow fluid design for smoother operation
  • 12 point hardware
  • Race derived caliper design provides excellent stopping and better pedal feel
  • Made in the USA in our Bradenton, FL location!

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.

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 Hats

Our billet aluminum brake hats remove the weight of a steel center all in one rotor while allowing for minor adjustment of axle offset thanks to our unique stepped mounting design.

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

I was hesitant to order this online but oh my GAWD, it's so much better than I thought it'd be. Soft and warm, and cozy. Far exceeded my expectations, and really took the Eames to the next level. Highly recommend.

Very nice quality

I ordered three of these, and they arrived promptly and very well packaged in a vacuum seal pack. Once you pull them out, shake them and fluff them a little bit they lose their wrinkles pretty quickly. They seem to be very good quality and are authentically sheepskin. The “white” has a tiny little bit of a yellow undertone, which is what I expected since it’s basically a dyed sheep skin. I would call the white color “natural” rather than white white. They are very thick and were a good price. I ordered two of the three foot-long hides and one 6ft foot hide. One of the hides had a slight odor to it that reminded me a little bit of eggs. It’s been laying on my bench all night and 24 hours later there is no smell. The other two hides had zero smell at all. I think it’s just a little leftover chemical smell from the treatment of the hide when they get it ready. It wasn’t overwhelming or overpowering. If you’re looking for the ultimate SUPER plush sheepskin, I recommend the Overland Sheepskin Company. However, for what I need these for which is just something to throw over my dining room table bench for a little cushion and aesthetics. It’s absolutely perfect and the right price point.

Beautiful Good Quality Sheepskin, Beautifully Packaged
Size: 2' x 6' (Sheepskin shape), Color: Creamy White, Size: 2' x 6' (Sheepskin shape), Color: Creamy White
Very nicely packaged and presented sheepskin rug. Seems like very good quality and is just as I imagined it would be based on my previous experiences with sheepskin. I don’t think it’s as soft as others seemed to think but it has been chemically processed and it is very similar in texture to what I remember from past experiences with sheepskin. I got this for the kitties to nap on - one seemed proud of me for bringing home a pelt and went into hunt mode. The other looked at me suspiciously like he didn’t really know me at all and was afraid I could be eyeing him for his fur! Hopefully once they both adjust they’ll enjoy napping on it 🙀😻

Full of beauty!
Size: 2' x 6' (Sheepskin shape), Color: Creamy White
This company takes pride in their work. The sheep skin covering is beyond what anyone could imagine. I purchased this for medicinal purposes. I found out I have SI joint dysfunction. And this sheepskin helps to relieve pressure points so I am using this as a chair covering for when I sit. The product came in a big box and then a plastic bag and then a third, well covered, plastic bag to protect the sheepskin. You will not be disappointed if you purchase this covering. The price was excellent. It will take your breath away. Very happy with my purchase. There was no odor when I opened the package. Many thanks for an excellent product and helping me to be more comfortable when I sit for short periods of time. :)
