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!

Weight: 16.20lbs Per Side

Included:

  • (1) 12.19" vented rotors 3-121981087-1
  • (1) 12.19" vented rotors 3-121981087-2
  • (2) Billet Aluminum brake hat 205-0007BL
  • (2) XS3 4 Piston Caliper (Choose color below)
  • (2) Caliper Bracket 17-0058
  • Complete Set of Pads 6-0002HPS
  • Hardware Kit 011-0278

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

Great, except for the edible one
Flavor Name: Chicken & Original, Size: X-Small
My elderly dog and my puppy both love these bones. They are 9lbs and 4.5lbs respectively and this is a good size for them. They also like the next size up and it is manageable for them as well. The only gripe I have is the edible one, it comes apart in larger chunks (that are still very hard) and my dogs swallowed a few before I noticed how large the pieces were. I decided to throw that one away. Its been over a week and no negative side effects so maybe just me being overly cautious. For the price (gold box) just the other two bones were worth it. They last pretty much forever for my dogs, and I would say they are moderate chewers. 4 stars due to the issue with the edible bone.

My little dog loves these.
Flavor Name: Bacon & Peanut Butter, Size: X-Small, Flavor Name: Bacon & Peanut Butter, Size: X-Small
These are the perfect size, texture, and density for my 9 lb chihuahua (rescued, of course! :)) He has a tiny mouth with tiny teeth and very little bite force so he needs a chewybone with a lot of give. I've been impressed with how clean these help keep his teeth (it's the saliva flow during the chewing that breaks down any lingering debris and the action of the nubs against the teeth and gums helps to rub off tartar and plaque, if you care to know the *why* behind it.) These are ideal for dogs like mine, and since small dogs tend to have a lot of dental problems due to overcrowded mouths, I couldn't be more grateful that these exist. These would probably also be good for the many rescued puppy mill dogs, who are often small breeds, who have dental issues due to malnutrition and exacerbated by overbreeding, especially in females whose bodies often rob the jaw bones of calcium for the sake of the fetuses they carry, when the pregnant dogs aren't given an appropriately enriched gestational diet. That leads to the little bleppy tongues sticking out all over that we often see in the canine survivors of back yard breeding operations, puppy mills, and the like. There are a lot of these dogs being rescued and adopted in the U.S. right now and these would likely be ideal for them. (In case any adopters of these little survivors are reading this. :)) These are for gentle chewers only, and there are a lot of dogs who fall into that category. They aren't , however, for dogs with an average bite or higher, which is where some of the complaints you hear about these are coming from. Know your dog's chewing needs and buy the size that fits their mouth, tooth type, and bite strength. My dog barely puts a dent in these after a year or more of chewing (watch for any degradation of the plastic and replace as needed, of course.) For little dogs like mine, these are just fantastic and I hope Nylabone keeps making these type of chew toys to keep our dogs healthy. :)
