Thank you. You have rated this product.

MEDIUM Stiffness Bumpstop, length 58mm. Popular with our stock class autocross customers because you can't change springs for stock class, but you can legally run these taller stops (which effectively raises spring rate legally). Stock class autocross customers often use these in the REAR, and the Soft stiffness (Red) 58mm in the front, to help balance the car when using our large Racing Beat front sway bar (stock class allows changing just ONE sway, not both).

Did you know that Mazda designed the NC to corner on the bump stops like the earlier cars? Now you can eliminate the factory understeer!

The right bump stop setup combines different lengths and densities front and rear to achieve proper neutral handling for your car. See our guide below to pick the right combination of bumpstops front and rear for your application. We use high-quality materials in our stops to add suspension travel and comfort while maximizing grip and performance.

Same bumpstops fit cars with Koni, Bilstein, KYB, and Tokico shocks, and your choice of lowering spring. Sold individually, price is for ONE bumpstop. You need TWO front and TWO rear bumpstops.

Recommended bumpstop combinations:

SPORT for LOWERED 06+ MX5s: 36mm front, 58mm White rear

SPORT for NON-LOWERED 06+ MX5s: 58mm Red front, 58mm White rear

COMFORT for NON-LOWERED 06+ MX5s: 58mm White front, 75mm Red rear

STOCK Class Autocross 06+ MX5s: 58mm Red front, 58mm White rear, AND Racing Beat front sway bar

If your MX5 is lowered by more than 1.5" then you are in the LOWERED category. The Comfort combination uses longer bumpstops that engage in a softer manner than the shorter bumpstops used in the Sport combos. The sport combinations allow for more free suspension travel before you hit the bumpstop, but they are a bit firmer than the Comfort option. All of our bumpstops ride better than the factory bumpstops.
