I found that reducing the negative camber on the rear wheels reduces tire spinning on launch dramatically and seems to improve wheel hop. Launch acceleration measurements:

Stock suspension height: 0.93 gs max
Lowered 0.9" (Eibach springs, -1.8deg and -2.7deg): 0.87 gs max
Lowered 0.9" Camber corrected to -0.9deg and -1.6 deg: 0.93 gs max

This is using the stock size tires on a similar day (obviously not the same day).

I can still get axle hop, but it is only if a drop the clutch abruptly with the engine at 2000-4000 rpm and the throttle partially closed. Without camber correction, the axle hop was a problem on a hard launch, now it just squats and goes.
