Have a 85 Iroc L69. Car drives great, but noticed suspension is not level when parked. All parts were replaced years ago but the springs, which are original.
Car sitting ground to arch: LF 27 1/8 RF 26 1/4
LR 27 1/2 RR 27 1/8
I believe it may be time to replace the springs. Any recommendations? Considering the Vogtland at founders.

 

I installed the Vogtland springs on my 90 Formula; fronts are great, rears are WAY too soft. I had to set the shocks at their most stiff to keep from bottoming out on dips. Wound up buying a set of stock replacement rear springs and cut 1-1/2 coils. Rear now sits about 1/2-inch higher than front. Front lowered about 1-1/4 inch.
