5X Racing Street Bump Stop Kit for 1999-2005 Mazda Miata

Miata Bump Stops

20915228 - 5XRNB46/46
Our Street Kit is recommended for cars at stock ride height/stock springs or slightly lowered. A good choice for street/mild sport applications where daily driving is the primary use of the car, or used as an OEM replacement to the weak factory bump stops when replacement is needed
  • Kit includes: four 46mm "comfort" bump stops for both the front and rear shocks
  • No washers or shock spacers are needed in the NB kits. The 1999+ Miata shock hat system uses the original washers in their original configuration, and they can be reused with these kits
  • Completely replaces the factory bump stops and works with existing shock hats and shock mounting hardware. The bump stops are universal to any 1999-2005 Miata OEM replacement shock using the stock shock mounting hardware. No special washers or spacers needed!
  • Proven Fat Cat Motorsports design and technology
  • Availability: Normally in-stock
    Pricing: $90.00


    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!
