5X Racing RX-8 Bump Stop Kit

RX-8 Bump Stops

22341977 - FCMRX8

Did you know that Mazda designed the RX-8 to corner on the bump stops like the earlier cars? Now you can eliminate the factory understeer by reconfiguring your RX-8's bump stops! We use high-quality materials in our stops to add suspension travel and comfort while maximizing grip and performance. Bump stop kits are based on your chosen spring rates, and please use our Mazda Bump Stop Application guide as a reference for the bump stop kits, information regarding them, and our recommendations. To see how our kits are configured, read the "Description" section below.

Availability: Normally in-stock
Shipping: In-Stock Items ship USPS Priority unless noted otherwise
Pricing: $80.00

The three kits we have available are listed in the drop down menu, they include 4 bump stops which will provide replacements for your entire car. The kits are pre-configured for desired use:

  • Stock/Street: Designed to be stock replacements geared for street use. This kit uses two 58mm "White" Bump Stops in front and two 76mm "Red" Bump Stops in the rear
  • Sport: Designed for MX-5's which are lowered using lowering springs on stock or aftermarket stock replacement shocks (ie: Koni, Bilstein, Tokico). This kit uses two 36mm Bump Stops in front, and two 58mm "White" Bump Stops in the rear. This is a stiffer setup than the street kit, and is designed to provide more shock travel on a lowered car
  • Stock Class Autocross Kit: This kit is designed for autocross racers who must use stock springs per the rules, but want to increase the spring rate by the use of bump stops. This kit uses two 58mm "Red" Bump Stops in front, and two 58mm "White" Bump Stops in the rear.

    If you would like to purchase the bump stops individually, please visit our "Custom Bump Stop's Kit" page on our site.

    If you're interested in replacing the shock dust boots, we recommend purchasing new boots if needed from Summit Racing - Pro Comp p/n 12127 black, 12128 red. We are unfortunately unable to supply the Pro Comp boots at this time.
