About this product

Part #: 83.529.004G.R3

The ultimate street braking system, with naturally anodized lightweight components adapted from our racing program. They use the same STR calipers, AeroRotors® and AeroHats® as the Trophy Race BBKs, but add silicone dust boots to extend service intervals and anti-rattle rotor mounting hardware for quieter street operation. They also include StopTech® Street Performance brake pads for high performance street and occasional track use, and StopTech Stainless Steel Lines. Any StopTech BBK can be ordered as a Trophy Sport Kit by specifying it on the order form.

What made you choose this particular product?
Bought them for the reduced weight, which I don't notice, and the price, which I definitely noticed. Pedal feel is a lot more linear and the little pause before the OEM setup really grabs is gone but I feel like the OEMs actually had better stopping power with a nicer (to me) pedal feel.
Is this your first time buying from this brand? Did you consider other brands?
Yes.

Was it easy to install? Any installation tips that will help others?
Be careful of stripped set screws! Those are pesky to remove if stripped.

What made you choose this particular product?
I wanted a visible brake upgrade; however I wanted a better stopping expierence more. So I went with what I felt was the best of both worlds. Cryo treatment was a must because I wanted to part to last as long as my car.
Is this your first time buying from this brand? Did you consider other brands?
No, and no.
Was it easy to install? Any installation tips that will help others?
It was super easy to install. Direct fit, bolt on.
Once you've had a chance to use the product, did it meet your expectations?
Yep, it sure it.
