Going to be replacing my front and rear springs with Moog stock replacement springs. For the front I am thinking about 5606 (421lbs spring rate) or 5600 (347lbs sing rate) for the rear 6377 (141 lbs spring rate) with a 1" spacer or a 5379 (121 lbs spring rate). What do you think my goal is to get my car to handle as good as possiable at stock height. My front suspension has been rebuild, I am using Global West G-Plus uppers with Delalum bushings in stock lower with Afco low friction ball joints with stock swaybar with poly bushings. My rear is Metco adjustable uppers and stock replacement lowers with greaseable poly bushings and a DSE 1" 1/8 adjustable swaybar. Thanks for your input. Kyle
