I got the pfs diff girdle and solid engine mounts. I did not get any wheel hop on street tires( bridgestone) or et streets on the 1/4 track. I haven't tryed it on the street yet since i installed the pfs girdle.

 

I finally completed everything I wanted with my suspension to stiffen the rear end: Tokico Illumina adjustables with Eibach lowering springs, new oem strut mounts, urethane rear toe link and trailing arm bushings, recently replaced all six rear pillow *****, and urethane differential mounts. I have 275 Potenza's in the rear and they stick pretty well in hard corners and I havent noticed anymore loosness in the rear suspension. This seems to have solved the wheel hop.
