So what's the cause of a squirrelly rear end?

Someone might jump in and tell me it's my subframe bushings

some might say dogbones or rear swaybars

well you're all WRONG! :p

Last night I went out with my roommate and drove around Myrtle Beach, SC (I just got back). Well I turned up the boost juuuuust a little (I've been driving with the gauge reading around 7-8psi, bumped it to read 10-11psi) and took her out for a spin.
In second gear I was just steadily driving at about 2000 RPM when I floored it - at about 3500-4000rpms at about 35+mph my tires break loose and my back end is squirrelling (?) all over the place! Man... this car can FLY!!!

And it was a dry night, about 80 degrees and it was on a flat surface so there.

And I don't want to hear from Mr. Todd about how he busts loose in 4th gear! ;) This is a first for this vehicle and I'm darn proud!

That was with 3.46 lsd, 20psi boost, 245-50-16 BFG G-Force KDW tires... just rolling into the throttle in third gear from around 40mph and lettin gthe torque overcome traction... tires started "scrubbing" while climbing towards 60mph... I let them scrub away for a second or two.

I miss driving that car during the winter. Just killing the tires in 2nd gear. Spinning like crazy at 60mph.
