I can offer that my Calvert setup performs a lot better with the Calvert shocks than it did with cheap C/E shocks. The tighter I adjusted the shocks, the quicker the car went, and the less rise it had. I run my setup at full stiff on the shocks and 2 flats of preload in the bars, and it barely rises at all; the rear bumper actually moves downward as the front end comes up. The axle separates slightly as it plants the tire. My car isn’t real fast, but it leaves pretty good for a 3875lb, 11.40 car. It typically 60’s in 1.58 and will put a little daylight under both front tires.
