PART NUMBER: 61-0792ND
If you're changing your springs and/or shocks, this is the right time to upgrade your bumpstops while you're in there to improve suspension travel and comfort while maximizing grip and performance. Sets are for all (4) corners, combining higher than stock densities front and rear to achieve proper neutral handling for your car.Makes an SCCA CS car faster.
Same part fits cars with factory shocks, Bilsteins, or Konis.

Your OEM bumpstops are soft and long. When you lower the car you risk riding on those stops all the time. You have three choices, option one is leave stock stops original and if you lower much you ride them all the time (car lacks free travel). Option two is trim stock stops one inch which improves free travel on lowered car but soft material remaining doesn't do the best job of stopping motion once into the stops. Option three is these stops, which are about an inch shorter than stock and higher density to better match upgraded spring rates...with ideal result that you spend less time on the stops and when you get into these stops they do a better job of cushioning because they don't reach full compression near as easily as the spongy originals.
Brian's application notes: this is my first choice for use with any lower springs and KONI for a street toy. This will give you best performance. However, if racing SCCA CS then balance needs are very different (see our long thread in our forum).
You can't dispute GWR's research and real world application of the products they sell. This was an easy purchase to use in conjunction with my locally sourced Koni shocks and swift springs. Incredibly fast shipping all the way to Canada with reasonable cost.
