I'll get new measurements tomorrow but when I talked to different people with lowered ZR1/Callaways about ride height, I was told:
Front: 25 3/4- 26"
Rear: 26 5/16-27"
Im pretty sure Im lower in both regards but im also running Ridetech coilovers. Front geometry should be the same (Ridetech shocks are Fox units made for this kit) and rear geometry is mounted differently from what I understand.
I've got no issues with bump or rebound and could likely go lower without detriment in ride quality but wanted to be able to clear a speed bump in my neighborhood.
