Thank you. You have rated this product.

Upgrade your Brembo brakes with a BIG 12.75" rotor! Now owners with Brembo brakes can have all the benefits of our Goodwin Racing big brake kits without having to discard the great Brembo calipers. It's a match made in heaven! These big rotors look great filling out the 17" wheels and offer big benefits in performance too.

This kit replaces your factory front 11" brake rotors with BIG 12.75" 2-piece rotors using brackets to relocate your factory front brake caliper out over the larger rotors.

Thanks to the 2-piece design, these rotors are even lighter than stock! 12.60 lbs each compared to the stock rotor 13.15 lbs.

- CNC aluminum hard anodized caliper brackets
- Lightweight aluminum rotor hats
- 12.75" curved-vane and heat treated friction rings
- All hardware included

The secret of a big rotor:
Larger rotors are often mis-understood. Sure they look great, but their big strength is in how much HEAT they can handle and shed. With a small factory rotor, the only way for the brakes to stand up to the heat of extended hard use is to use a race pad that can survive well over 1,000 degrees. That is just fine for a race car, but racing brake pads are terrible for road use (LOTS of dust, noise, and often NO bite when cold). Ever wonder how Porsches and similar cars can drive around the street daily on the same brakes that they can go to the track and turn laps all day with? Those cars use a street performance pad, and the secret to those pads not overheating under hard use is in the BIG rotors on those cars. If you want a car that can "do it all", get to/from work every day and lap the race track on the weekend, big brakes are the key.

Our favorite street performance pad, the Porterfield R4S, pairs great with these rotors for a do-it-all street/track fun car using street tires. For extreme performance 200tw summer tires we recommend a pad with more bite like the Porterfield R4-1. For serious racing duty, we still recommend a track-focused pad.


YES, this kit fits with factory BBS wheels. However, the wheel weights must be relocated from their factory position just behind the spokes of the wheel in the barrel to a position further towards the inside edge of the wheel where they won't conflict with the larger brakes. You can easily remove the wheel weights with a flathead screwdriver at the time of installing the big rotor kit, and then drive the car down to a tire shop to have the wheels/tires re-balanced. In many cases, you can hardly tell that the wheel weights are missing, but it is still recommended to get them re-balanced (unless this is a track car in which case we often do not have race tires balanced). Be sure to specify to the tire shop that you want the weights placed further towards the inside of the wheel.

Roadstersport II was a great purchase, easy install, and sounds great.

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.
