    We don't use YOUR vehicle for testing, we purchase our own shop cars. Our product is always ready and thoroughly tested before it's installed on the first customer's car. With results to back up our products, Brentuning is the easy choice for your aftermarket needs.

  • We Didn't Forget About You!

    We haven't forgotten about our roots and what made our shop so popular in the first place. Software and hardware solutions for your late model Evo or STI are always welcome





Until next year 🙂
