I searched and came up with nothing.
I know that most bolt in 9's angle the upper bars downward towards the chassis. Where are you guys Instant centers ending up?

Im debating running a bolt in 9 vs an 8.8. I'm wanting the rear to sit at least 2 inches lower than stock Monte Carlo SS height, and the front 3 inches lower.

A few vendors have brackets that allow adjustment of the upper bars of an 8.8 in a Gbody. This may give me a better bar intersection point, as I'm not wanting to hit the tires too hard.

Last, I'm planning on running 28 10.50's with the lowered car. Is this possible with a stock tub/ Frame rail?

I know this isn't a Monte site. But, Unless your into autocross or Pro-touring they don't have much insite over there.
Any thoughts?

I ran into alot of the same questions about my 12 bolt and getting new control arms. check out base line suspension and theres a calculator to plot out your rear suspension and instant center.

If some of the others on here will get measurements of theirs, that would help you. Also I run a 15x8 with a 28x10.5s MT ET Drag. with only the fender lip rolled.
