I am in the process of replacing the upper/ lower control arms with UMI adjustable uppers and UMI lower lift bars. While I am at it, I went ahead and removed the rear axle since I'm getting 3.55 gears installed this weekend anyways. I'm also installing lower torque box reinforcements while I have everything stripped. Then full length sub-frame connectors while I have my welder buddy over.

I've read alot of different comments on pinion angles, but unclear on what to set it at.
I read to set it at -1 deg, -2 deg. even -4 deg.

This is my daily driver, but I plan to hit the strip from time to time.

Any advice would be appreciated.

Do those control arms have Poly bushings? Im not familiar with the UMI's

This should be of some help.

Pinion angle should be 0* under full acceleration. For every degree that's it's above or below 0*, you lose a little bit of power.

The first thing to do is understand exactly what pinion angle is, and what it is not. There's always a lot of confusion over that. The pinion angle is measured against the drive line (not drive shaft) angle. It is NOT measured against the horizon.

It's hard to determine the exact static angle. Because it's really only important when you're under full throttle, the rear suspension is compressed, and the pinion is fully rotated upward.

Generally, a mild street car with a mostly stock engine and suspension should shoot for about -2*. That's pretty darn close.

Thanks, almost stock. Your ride kicks so much ***.....

I have the entire rear of my car yanked apart right now and want to get things right the FIRST time.

I have paid my dues on other projects in the past, but I have a new found respect for "been there, done that...." feedback.

^^^Thanks very much you for the complement.
