I don't think lowering blocks would be a good idea, you'll probably wind up with bent springs or worse if your car makes a reasonable amount of power. If you want to lower it, make the adjustment at the front hanger.
the car is going to have the inboard spring kit, so the front hanger will be replaced by a box instead, otherwise i would just flip the front hanger like most do...I thought lowering blocks with the SS springs was okay? I guess i could get them dearched if i wanted to lower it a bit...and yes scott i know i should try and just put her back together, but now that i have her apart i want to do what i can...those leafs back there sag more than my grandmothers couch, so im thinking now is probably a good time to replace them since im swapping rearends and doing the spring inboard and will have easy access to it
