A must-have with any shock/spring upgrade. Our kits are an integrated package (not just a part) and are designed for your particular setup, including washers and spacers (when needed, to limit travel and protect your shocks).
This kit is designed to replace the factory rubber shock bump stops on 1990-1997 Mazda Miata's
Each kit comes with four 46mm "comfort" bumpstops, four fender washers - and if applicable - four spacers for certain shock applications, which is enough to replace all bumpstops on the vehicle
Our "Street" kit is geared for touring/street use and maximum comfort by utilizing a softer rate foam bump stop. It is best paired with stock spring rates and not recommended for cars lowered more than a half inch. If you are looking for a more firm bump stop, or participate in auto-x and track events, please explore our "Sport" and "Track" kits.

Partnering with Fat Cat Motorsports allowed us access to their proven engineering and techniques on how to custom tune your suspension by way of bump stops. When the average person thinks about suspension, they think springs, shocks, and bushings. Bumpstops are the "cushion" between the shock body and the shock mount, without them the metal shock body would come in contact with the metal shock mount during full shock compression causing damage, and a terrible ride! The factories take bumpstops into consideration, however they tune them to be used with factory shocks and springs and often use inferior materials like rubber (which is unforgiving when compressed) or lower quality MCU (micro-cell urethanes) which can't handle the thermal loads as the higher quality MCU bump stops we use. When you start customizing your suspension by replacing the shocks and springs, the factory bumpstops now become mis-matched to the rest of your suspension. Most people will try and reuse the factory bumpstops, but this will not yield optimal handling characteristics because of the now lower and shorter suspension travel plus lower bump stop quality. When you upgrade your springs and shocks to lower your car or if you simply want to improve the handling and durability of your stock suspension, bumpstops can be the "missing link" in your suspension that you never thought of!
