Merv, I'm a little puzzled as to why you need to resort to those adjustable Z arms. I dialled 5-6 deg positive caster into my front end last weekend and the wheels are still closer to the front of the wheel arch than the back, when viewed side on. There's a good inch of spacer tube on the back of the top A-arm, which I could trim to lay the top arm back even further. I went from 0.5 deg to 5 deg with only about 5mm of shims on the front spacer. What I'm saying is that my kit has way more adjustment than I need and that's with a power rack where I'll end up with about 7 or 8 degrees eventually. Does it have something to do with correcting geometry for bump steer?
