Dimensions & Specs

Important Notes

This part is specifically for racing competition only, so if you’re planning on hitting the streets, you’ll need to look elsewhere. And remember, if you’re outside California but have a California emissions equipped vehicle, you’ll need to sign a Vehicle Compliance Waiver before you can make the purchase. You can find that here.
