I've lowred my car and it's currently sitting way too low on the front.

I'm using #3 spring shim which is 13 mm.

If I use the #5 spring shim which is 21mm would this raise my car by 8mm. Or do you double the size difference which would mean it raises it 16mm (I have read this on a different forum not sure how true it is).


Car is a w210 E320 cdi
Thanks
 
When I discussed ride height for my W209 with my indy, he said the rough guide was 2x the shim difference. This is based on the spring being located approximately halfway between the wheel centreline and the control arm pivot point.

I didn't change shims though, so unfortunately cannot report on the actual difference.

Thank you buddy. I've heard similar information so I'm going to assume this is true
