    Most popular with stock class autocross racers because the rules don't allow a change in springs, but you can legally run taller bump stops (which effectively raises spring rate legally). Stock class racers often use these in the RED (soft) stops in the front, and the WHITE (medium) stiffness 58mm in the rear to help balance the car, especially when using our large front sway bars. 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.
