i'm not sure about the verts but the best bang for the buck to reduce wheel hop in the coupes is a pinion snubber, which costs about $7 and takes about 45 minutes to install, most of that spent removing the bins to get a drill into the center tunnel area above the nose of the differential.
this also helps keep your $180 differential mount from ripping under the stress of wheel hop. |

The 91 convertibles came with a 4.10. Info direct from the 1991 sales brochure.

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.
