Does anyone know who makes bump stop packers that are small enough to work for the Koni Sport 12mm shock shaft? Smallest I've found is from RE Suspension for a 12.7mm shock shaft, but the "slot" distance is right at 12mm and half of them don't stay due to manufacturing tolerance.

 

Hey, Koni Sport shocks on Miatas use a 12mm shaft, and finding packers that fit tightly without falling off is a common headache. The RE Suspension ones for 12.7mm are the closest most people find, but tolerances can make them loose. Many NA/NB owners just run the nylon washers that come with the Konis or trim their bump stops instead of adding packers. Good-Win Racing sells bump stop kits specifically for Koni Sport (5/8" shaft) that include the right spacers/washers. If you're trying to limit travel to prevent rubbing, consider shortening the bump stops or adding a thin fender washer stack as a simple workaround.
