Performance questions, answered

What modifications would you recommend starting with?

If you’re after more horsepower, software upgrades on Porsche, Audi, BMW or Volkswagen models often provide the best “bang for buck.” If you’re focused on lap times or handling, starting with braking or suspension upgrades is ideal. Our team will guide you based on your vehicle, use, and goals.

Can you help me source parts?

We sure can and generally prefer to do so. Having Zaks Auto source your performance parts creates a seamless experience for both you and our technicians when it comes to installation support and

warranty concerns. Rest assured that Zaks Auto almost always can match the retail price on any given component and we are happy to give you that unboxing experience if you desire when the time comes for installation.
