Anyone have the '90 Z51 front & rear alignment specs handy? I had a '90 Z51 in my past and liked how the car felt. I sold my manuals with the car so I can't look them up.
I'm investigating suspension work for the GS and would like a "known" baseline to compare to before I start swapping parts and changing settings.
Talk to Bobby at Guldstrand Engineering..they have a ton of experience with C4 alignment. I used their specs on my 85 Z51 and great handling and no abnormal tire wear at all.
I used their touring specs which are as follows:
Front
Camber 0-1/4 neg
Caster 2-7 pos
Toe 1/16-1/8 in
Rear
Camber 0-1/4 neg
Toe 0-1/16 in
If you are racing or autocrossing obviously you would want to get more aggressive but this has worked great for me.
