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

Amazing. The Perfect Pillow for Side Sleepers with neck pain!
Size: Queen (High Loft), Number of Items: 1
I do have to update my experience. This still is a very comfortable pillow, it's just I can't sleep with it under my head (it's now my hug pillow). After using for 2 weeks, I developed severe neck spasms. Pillows are very individulized and as it turns out, I probably need a firmer pillow than this "highly" comfortable pillow can offer. Will NOT change my rating. Wow! I'm impressed with this pillow so far. I'm a side sleeper mostly but chose the medium-high loft 6.2" as recommended which was the perfect height. I didn't see any taller options but this has turned out just right. I did hours of research before chosing this product, which turned out to be advantageous. It's not as cooling as my old memory foam pillow with the gel layer but it stays cool long enough that I don't have to move the pillow around to be comfortable before falling asleep. It's surprising lightweight. I like it much more than any memory foam I've ever had. The best news was that within a few days my headaches and neck pain have improved by 80%. I am really very impressed with the quality of this pillow. It is softer than I anticipated but still firm enough to keep my head elevated giving me perfect spine alignment and great support. It truly is the MOST COMFORTABLE supportive Pillow I have ever slept on! The smell is only minor at It's worst and has nearly disappeared after just 4 days. It is a mild latex smell but definitely NOT petroleum. It's in the moderate price range at ~$100 and worth every cent. High value for the price. I really really like this pillow and highly recommend it. Big fan! Might irder a 2nd as a backup if it doesn't last but it's so well made I feel that won't be a problem.

Excellent comfort and support!
Size: Standard (Mid Loft), Number of Items: 1
The pillow feels premium from the first night and delivers soft and stable support. The pillow holds its shape and didn't have any chemical smell out of box. Worth the price and I would buy it again.

Not really medium, but a quality pillow nonetheless
Size: Standard (Mid Loft), Number of Items: 1
It is absolutely the case that with this type of product, most people who review it don't actually know what they're talking about. Latex foam pillows are not like any other kind of pillow, so your expectations have to be completely different. It's not about thickness, height, or anything else but comfort. Comfort in this case comes from you choosing the correct level of FIRMNESS. Since each company has their own idea of what constitutes each level, the difficulty is figuring out which one is going to work for you. Your spine - including your neck, should not be anything but straight/aligned when your head sinks in. Regardless of what the pillow LOOKS like, it is how your head lays that matters. Latex foam is not like memory foam AT ALL, so don't expect it to be. LF bounces back immediately when you move off of it, and it can last for a very, very long time with proper care. Yes, it does have a natural, rubber odor. This fades a bit with time, but will never go away. After all, it IS a rubber product. EXPECT A SCENT! To keep yourself from being bothered, and to extend the life of the pillow, use TWO different types of pillow covers. As a first layer, I use one meant for encasement from allergens and bugs. It's waterproof (not vinyl, and not loud). It's the kind that cannot go in the dryer after being washed. The second layer is a simple cotton cover/case that you should wash and dry depending on factors like oil production, frequency in hair washing, and frequency in sheet changing, etc. Using both will dramatically extend the life of the pillow. Water is the enemy. Moisture will cause the foam to break down into pieces. The crumbling is pretty nasty, so avoid it! The case this one comes in is admittedly cheap and pathetic. Not every company has such poor ones, but it won't make a difference if you add the layers I have suggested. *This IS a real latex foam pillow. I have owned enough to know what they smell and feel like. I bought a "medium". I would call it a firm "soft", and so it wasn't for me. Find the right firmness for your neck and sleep needs, and don't blame the damn company for your choice! These ARE the correct height, they smell normal, and the price is average (they're ALL overpriced)! *This does not seem like a completely latex product, but it is close enough that if it were actually medium firmness, I would have kept it.

Perfect size, perfect pillow.
Size: Queen (High Loft), Number of Items: 1
For me, This pillow is the be all and end all when it comes to comfort. I simply melt into luxurious sleep. I have had a bad neck since my early 20’s, so a pillow that doesn’t fit me, can break me. I have spent soooo much money on pillows trying to find The One. Foam is the only way to go in that regard. Another aspect about this pillow that is particularly important to me is how well it fits into my satin pillow case, with no room to slide around, or for the material to bunch up. I allowed the pillow to air on a chair for 24 hours before use, but am still getting a slight odor.
