suspension arm attitude at ride height

PostPost by: mini64 » Wed Sep 28, 2011 2:37 am

As I rebuild my car I am checking wheel/tire fit under the body. The car is stripped right now so not at the correct ride height. I need to weigh it down to get it correct for the check. Could someone give me a couple ground clearance measurements at race ride height? Or what angle the suspension arms are at?

There is a drawing of the suspension in the workshop manual with dimensions. For racing you can lower normal ride height by a couple of inches to 4inch / 100 mm if you want with roughly 1 inch coming out of lower profile tyres and 1 inch out of the suspension. Personally I prefer it a little higher as it takes out to much bump travel when set this low and the race tracks in Australia are pretty rough.

The front lower arm is near horizontal if you lower it about an inch

The 175 or 185 / 60 tyres with foul on the guards on full opposite lock but are ok in normal steering and bump deflection as they tuck under he guards in bump if you get the wheel offset right.
