Products available for 2006+ Miatas and 2004+ RX-8
using MS-R package or aftermarket Koni shocks

Did you know that Mazda designed the NC and RX-8 to corner on the bump stops like the earlier cars? Now you can eliminate the factory understeer! Bump stop kits are based on your chosen spring rates, or check the application guide for our recommendations. We use high-quality materials in our stops to add suspension travel and comfort while maximizing grip and performance.

Unless otherwise specified, 1 kit supplies all (4) corners, combining different densities front and rear to achieve proper neutral handling for your car
Purchase bump stop kits from our distributor Good-Win Racing

  • Step 1 - Choose bump stop type (Application guide)
  • Step 2 - Re-use your OE dust boots or purchase new boots if needed (we recommend Summit Racing - Pro Comp p/n 12127 black, 12128 red).
  • Step 3 - Purchase bump stop kit from our distributor Good-Win Racing
  • NOTE: Spacers are not required with 06+ Koni shocks
NOTE: For MS-R packages, the bump stop lengths are 55mm front and 40mm rear. To upgrade to an FCM solution and reduce mid-corner understeer, do the following:

Use our 58mm red front cut to 50mm and our 58mm white rear cut to 40mm (removing the thicker end).
