I had mine set in the next to the bottom hole on the 1/4 max four hole front mount, I moved it to the bottom and ended up changing from Strange single adjustable coil overs to the same set up with Strange double adjustables and switched from a 175 lb spring to a 150 lb. spring. The car ended up doing 1.37 60 ft. on a set of 13x30x15 M/T ET Street bias ply tires Try moving them up and down , lower hole for the good tracts and the higher hole for the bad tracts Make sure and reset the pinion angle also each time with the changes, my car like from negative(down)3 to 5 degrees from the pinion gear to the driveshaft Whats your thoughts on how the car drives now compared to the old set up
