No help No help Better in bumps Bumps no help, more U/S More rear grip - no change in bumps Reduced pitch change - hurt it in bumps - rear nervous Reduced U/S by 50% - Same in bumps U/S gone - reduced U/S by a lot Bet ter in bumps now - slight nrevous rear Slight hel p but not much better in bumps Hur t turn i n - small change Very l ittle difference - slight more slip i n car U/S Big time - not good Worse in bumps - less nervous at rear Small impr ovement bumps - more grip - l ess O/S Ver y bad in bumps - super harsh - cant drive it this way Not much change at all in rear Felt faster in str aight l ine - good balance Felt faster in str aight l ine - good balance No change in grip - O/S balance bad Minimal change in bumps - O/S mid out Better in bumps - sli ght O/ S Worse in bumps - very har sh Much better in bumps Bumps same - Power down better

Bad in bumps

Turn in

Bet ter power down on exit. Less exit OS Less power down OS. Better t ransiti on. More cr isp Less OS again. Car will carve at the rear now, not slide RARB fell off - bi g power on OS Much better center to exit. Less OS power down Better again with less OS on etit. More r ear gr ip. Better grip on exit of slow turns now, still good fast turns Not much change at all in power down. No change in fast turn More support in high speed t urns. Hurt Power down OS, slids now. OS now - f eel rear fall over. Lost suppor t. No change in sl ow tur ns. Big US now. No falling over feeling at all. Fal ling over feeling back. US when it does, but may not be pushing hard Less push and less snap on exit. No change in slow turns or turn in. Car is now connected. More US but still feels soft in the rear Falling over not as bad. Braking worse. OS slow t urns on turn in Falli ng over reduced. Still feels soft at rear. Power down better. Better in the r ear, not as much movement Car is very good in fast smooth turns from the rear. Needs more turn in bite. Feels t oo sof t at front Helped the turn in. It bi tes now with a littl e roll. This rear package i n smooth tur nsis great. ItIt is not so good in the bumps - 17mm RARB? Learning tr ack. Car not good in bumps fr om the front . Better in bumps at front. Now U/ S in smooth turns U/S is gone now in smooth turns and the car i s about the same in the bumps Much better in the bumps now. This was a very good change f or the exit out bumps Very good. Turn 9 is much bet ter, car has more grip, and is stable - I like this set up Sl ight O/S high speed turns Better in Talladaga turn (Hi gh speed), not too point y Less O/ S now, still have some O/S in mid speed turns af ter the car takes a set Bi g O/S in high speed turns
