Mazda Bump Stop Application Guide

Bump Stop Descriptions and Uses
- 58mm Mixed Density - available in red, white and blue (soft, medium, and hard) densities. For 1990-2008 Miatas used for aggressive driving (on stock springs) or Stock-class autocross to stiffen effective spring rate when stock springs must be retained. Mix densitities front/rear to achieve desired handling balance (usually one step stiffer rear vs. front when using a large front bar). May also be used on Penske/Koni 28-series shocks to prevent tire/fender contact and supplement primary spring rate ala NASCAR/Indycar. Can be trimmed to make thinner to accommodate extemely lowered suspensions such as "slammed" or "stanced" street cars to gain (or limit) suspension travel, or to control ride height tire-to-fender contact on vehicles with pulled "flush" fenders.
- 76mm Mixed Density - available in red, white and blue (soft, medium, and hard) densities. For 2006+ Miatas, 76 red may be used as a OE replacement bump stops. For custom applications stops may be cut to varying lengths
