I'm messing with stuff in my driveway and trying to give myself the best chance of leaving the alignment shop with the best alignment I can get.

I tinkered with the UCA's and the washers underneath and was able to maximize negative camber while also increasing castor.

Now for the rear my questions are: will the same UCA tricks I used up front work in the rear?

And is more always better when it comes to positive castor in the rear?

Any other way to adjust castor in the rear that I'm not aware of?

Thanks

If you have a C6Z or ZR1 there are more options for adjusting rear castor as they have the same upper arm connection in the rear as the front. On the standard car when you change rear camber you are also changing rear castor some amount. If you want more adjustment on the steel chassis then you're into offset bushings in the upper control arm.

I don't know what rear castor angles to target - when I'm adjusting that I'm targeting a bump steer curve and using a bump steer gauge.
