I like and use the QA-1 10 way ajustable rear shocks... I sea you state you have aftermarket springs and aftermarket lower control arms, do you have different upper control arms? are the rear coil springs of the lowering type?...... and wth the above mods, have you ever checked your rear pinion angle?

to check the pinion angle, you need a pinion angle tool or something to measure the angle at the rear flange wth the car on the ground...you'll be looking for a negative # from @-1 to -4 but the closer you get to the -4 the more agressive the car hits the tires, most "street" cars wth stock rubber suspension bushing are good wth a -1 to -2, cars wth poly bushing can go -2 to -3 and cars wth solid or spherical bushing can go -3 to -4.....

also the lowering springs prob arn't helping much, it's pretty hard to get a lowered car launch and go down the 1/4 efficiently and effectively;)
