Thank you. You have rated this product.

This is an upgrade kit for those who ALREADY have our Goodwin Racing 4 piston or 6 piston caliper kits. This adds the rotors and upgrades you to our FULL 12.88" big brake kit. This will NOT work on your car if you do not already have the caliper portion.

Replaces the stock 11" rotors with big 12.88" 2-piece rotors. Includes new brackets to place the Wilwood calipers over these larger rotors.

Last week I spoke to Brian, I ordered a aluminum Koyo 37mm radiator for 97 Miata. Brian, you run a first class show! It arrived the next day. It is a fully polished work of art. The welding is perfect. The fit is perfect, old radiator slipped right out, new one slipped right in. Perfect. I am very pleased. Thank you.

I have to say that your website is one of the cleanest, most functional and easy to use. There are a lot of independent part sellers that have horrible websites and it was a joy to use yours and even explore the customer car gallery and the good win build page. Thank you for a great experience.
