You can start to reach the 7-8* caster range when you start getting really low on ride height. More normal ride heights, you'll probably cap out around 6*.

Yes, caster changes will change steering characteristics including bumpsteer and ackerman angle. Not significantly, but it is there. It wouldn't be too difficult to add adjustable bumpsteer to these cars...

I don't take credit for this, RTErnie clued me in.

Yea. This is pretty much what I did. I maxed out Caster with the Ciro plates until I had an acceptable amount of rub on the rear fender well with 285/30/18. On full lock it will rub slightly with full tread tires. Currently running 5.4 degrees I believe at a 1.25" front drop.
