The Sport kits are the evolution of the legendary Fat Cat Motorsports "Sport" Bump Stop kits. Instead of using the cutoff lower portion of the 76mm Blue bump stops to create the 36mm front bump stop used in the Fat Cat Kits, 5X recreated their awesome kits with our own specially molded 36mm bump stop.

Fits 1999-2205 Mazda Miata's with OEM, OEM replacement shocks (ie: Bilstein, Koni, etc...), or any shock with no larger than a 5/8" shaft.
Kit includes: two 46mm "comfort" bump stops for the front, two 36mm front bump stops for the rear with medium density.
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!
Designed as an upgrade to the weak factory bump stops and provide a middle-ground between the Street and 36mm kits we offer. Recommended for most off-the-shelf lowering springs such as: Tein S-tech, Eibach, Racing Beat, H&R, or Flyin Miata
Proven Fat Cat Motorsports design and technology

Optional '99 - '05 top hats are available
