In reality, there are a simple tuning tool for corner entry under braking. If you have the right setup, they gently stop the front end dive at your target travel amount. Every Time. This loads the front tires more than non-bump stopped setups AND keeps the rear tires loaded. That consistency grip is confidence inspiring, while allowing the driver to learn, experiment & even make errorswithout costly crashes. Tuning?If the car is loose on entry under braking & turn in, add more shims. If the car is tight or pushy under braking & turn in, remove shims. Yes, it is that easy if you have the right bump stop rate curve. While we use dyno rating of bump stops, durometer is a simple way to tune.On rough tracks we run softer bump stopsrated at either 50 or 60 durometer. On smoother tracks, we can run stiffer bump stopslike 70, 75 or 80 durometerto gain more grip & quicker lap times. Pro racers looking for every ounce of grip & lap time will run very hard 85, 90, 93 or 95 durometer bump stops, as long as the track is smooth enough.Another cool tuning strategy for road courses is being able to tune the grip on corner entry of left hand & right hand corners separately. If the car is loose on entry of left hand corners, simply add a shim to the RF. If the car is tight on entry of left hand corners, simply remove a shim in the RF or add a shim in the LF! Reverse this if the car is tight on RH Corners. Ron will share more tuning tips with you once you have your bump stop setup.942'
