2008 GT500 with a vibration/wheel hop issue only in second gear. Occurs mostly when shifting from 1st—>2nd and then accelerating moderately or fully, and will sometimes do it on a hit rolling in second gear. Only does it in third at low rpm’s and heavier throttle. Car has Mickey Thompson ET Street SS that were impossible to balance and a set of rear only lowering springs (<1 inch drop). Car also has a set of LCAs but has stock UCA.

Can’t figure out if it is the car is trying to grip, and the result is hopping, or if the pinion angle is off due to the rear springs. I do not have any vibration issues at speed either, only when the car is under load in 2nd gear and sometimes 3rd gear.
