Alignment Specs Help.
Hi All, I have an 05 base I just put z51 bars on and it has the F55 suspension. I was going to use PFADTs website for performance street alignment but their toe range for both fronts and rears seems huge. I daily drive the vette but also do a few auto crosses and live off a mountain winding road so it sees frequent twisties. What front and rear toe settings do you like?

I have always heard keeping toe near 0 is the best. Total inder .05, for the front and the rear even less.
If you do see a lot of turns and at some speed the camber will be fine it is the toe that will cross scrub for tire wear.
I run the Pfadt street spec to the tee and all is wearing evenly at 30 lbs cold. My toe is total .03 front and zero in the rear as best as I can recall.

Total toe: Chevrolet specs front 0.10+ 0.20 degrees.
Rear 0.00 + 0.20 degrees
Pfadt Street Specs: Total Toe Front MIN 0.17 Max 0.0 degrees Rear MIN 0.17 Max 0.0 degrees.
Obviously stricter tolerances in the Pfadt spec, but still within the Chevrolet range.
Rear 0.00 + 0.20 degrees

I always set the toe on any car toward the positive end of the specs (toe in ). It seems to tighten up the steering and it usually has the effect of needing less input to keep the car going straight down the road. I used the Pfadt street specs on mine except for the toe. Pfadt recommends 1/16" (.29 degrees) negative, I set mine to .1 degrees positive. This is the factory toe setting.

Damm these threads constantly come up. Just get a good wheel alignment guy who knows what he is doing with a Hunter machine and have him set the specs dead center of what the factory calls for and be done with it. I'm on my third C6 this one a 13' GS and have never used anything but the factory specs set dead center. Never had a wear or handling issue. I really don't see the constant bickering over specs when they are right in front of you in the form of GM!
