OVERSIZE 1The key difference in these QA1 coilover models is the range of adjustability. These Double Adjustable units feature seperate knobs for compression & rebound. With 18 settings for each knob, that's 324 possible combinations! They made this valving option change to provide more definitive valving control settings that can be felt as well as graphed on a shock dyno. The all new QA1 coil-over system allows the enthusiast to remove the old transverse spring and utilize true four corner "tuning" at each wheel through the use of the coil-overs. In general, we believe the 550 lb. spring rate is a great street/strip set-up.
