Perfect brake bias wins championships. The TR20 is a lightweight, 2-piston forged caliper engineered to be the essential rear counterpart to our TR65 or TR40 front big brake systems. This is not a standalone upgrade; it is a precision tool designed specifically to provide adjustable rear brake bias for stable, controlled, and repeatable threshold braking without overpowering the rear axle.
The compact and exceptionally rigid two-piece forged design reduces unsprung mass and simplifies packaging in complex race car rear assemblies. Featuring ventilated, bootless stainless steel pistons for maximum heat resistance and consistent pedal feel, the TR20 delivers the reliable performance needed to fine-tune your car's braking dynamics. Each kit is a complete, bespoke, bolt-on solution engineered for your specific application.
The following specifications are the core engineering data for the TR20 system. Total Piston Area and Net Weight are critical metrics for race engineers dialing in brake bias and reducing unsprung mass. Your bespoke kit can be configured with the rotor and pad options detailed below.

Every TR20 kit is a custom-tailored solution. Our collaborative process ensures perfect integration with your chassis for a true bolt-on installation.
Your project begins with our motorsports engineers. We'll conduct a detailed consultation to understand your chassis, knuckle design, competition class, and performance goals.
For OEM Knuckles: Provide vehicle year, make, model, and detailed wheel specs.
For Custom Knuckles: Provide CAD files (IGES/STEP), technical drawings, or precise measurements of the mounting points.
Our engineers will design the bespoke mounting bracket and rotor hat for your application and provide final design specs for your team's approval before manufacturing begins.
Yes, this is a comprehensive, vehicle-specific system engineered for a complete bolt-on installation. Each TR20 kit includes:

Start Your ConsultationYou’re here because you’re passionate about your ride, and so are we. We want your TTSPORT brake upgrade to be a total win. Here’s some straight talk to make sure everything goes smoothly, from fitment to bedding in.
Look, we know you get it. Your brake kit is custom-made for your specific car. That means once it's built, it's yours. We can only accept returns if there’s a genuine quality defect from our side.
Sometimes, aftermarket wheels can be tricky. Depending on the design, you might need spacers for clearance. We’ll do our best to help you figure it out, but issues related to wheel spacers don't qualify for a return.
To get this right the first time, we need your help. Before you order, please give us the following info:
We’ll likely ask you to confirm some measurements and send a few photos of your wheels. Please double-check everything you send us. TTSPORT isn't responsible for fitment issues if the specs you provided were off.
We check every single part before it leaves our shop. When your kit arrives, give it a good look-over. If you spot any potential quality issues, let us know within 24 hours.
This is key to awesome performance. Don't skip it.
We build our kits to last, and we stand by our work. Here’s the breakdown:
