From inspiration after reading Ron Sutton's post about chassis and suspension in Rob's thread, I also lowered the car 1.5" in the front and 1.0" in the rear to lower the roll center as much as possible... if your reading... thanks for the great info Ron. I will have some questions in a future post to ask about front and rear shock compression and rebound dampening settings.
I lowered the car as much as possible... while maintaining functionality with no rubs while cornering.
New measurement from floor to front fender lip, 23-1/4"
New measurement from floor to rear fender lip, 24"
New stance after lowering
Rear set up is Global West reverse eye 2" drop Cat-5 leafs with a 3/4" spacer between the leafs and axle. The front set up is Global West tubular A-arms with 600lb coils cut to 12" length.
The sub frame is now 4-1/4" off the ground, and the headers are about 3-3/4" off the ground.
So far no tire rubbing or scraping.
