If you want big front brakes but don't have a big budget, NEUSPEED's economy upgrade kit is just for you.

We supply the brake rotors, the NEUSPEED billet aluminum caliper adapters, and custom stainless braided lines. All you have to do is buy the Porsche Boxster calipers from your local Porsche dealer or dismantler, and brake pads from us or any other Porsche parts supplier.
