I've got springs. Still have wheel hop. Heck, I can't use more than 1/4 throttle in 1st in the morning w/o spinning(and hopping) like crazy.
Bored132, you also have the benefit of an LSD (as does the original poster). I wish I had the $$ for the groupbuy on them.
Girth, yes the mirrors vibrate. If my softer bushings ever come in I will toss them in and let everyone know the difference between the auto and manual AWR mounts.
Even with the added vibration, I will NOT take the rear mount out. I think the car feels much better with the mounts. And I drive 150 miles a day and about half of it is bumper to bumper. That's IMHO though.
