Turning up the rebound enough to resolve the bouncing may increase the compression enough to give you a harsh ride. The trick is to find a shock that will allow you to increase the rebound with a minimal affect on the compression side.
The other problem you might be experiencing...the QA1 is a twin tube shock...the working diameter of the piston is 1". The same OD mono tube shock has a piston diameter of 1.78"...almost 3x the effective working area. The bigger the piston, the more efficient the oil control. Very important on a heavy car or one where you want precise and repeatable performance. A twin tube design is typically adequate for most civilian cars, but the mono tube design has been incorporated into the higher end units such as Penske, Ohlins, JRI, ...and RideTech (you knew it was coming, didn't you?  ) |
Wow, very nice! Thank you for the insight. My machinist and I have been drooling over switching to Ridetech coilovers for a while (he runs QA1 as well) and looks like I might have just found my motivation
