REVIEWS

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.

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
