I started with a set of Heidts tubular upper and lower control arms, along with their tall 2" drop spindles. These raise the ball joint 1 1/2". I know many on this site are not drop spindle fans, but I have no issues. I do recommend running a 17" or larger wheel with the correct B.S. The coil overs are QA1 #GMP1450-1 they come with a higher rate spring for a big block and are fully adjustable. The rear are stock multi leafs that a spring shop de-arched roughly 2 3/4". I fine tuned the rear height by playing with different size home made lowering blocks. Should try and stay at 1" or less.
Eleanor's Nemesis thanks. Front sits at about 25 1/2" ground to lip, can go lower but would have clearance issues with header collectors. No rubbing on fender or wheel well. Springs are fairly stiff. Slight rub on sub frame at extreme turn. I also have AGR's quick ratio 12.1 box, about two turns lock to lock.
