Need some help with 69 Z/RS front suspension.

[GMJim]

Thanks everyone.
This car is more of a weekend driver. I don't track it and don't really want to get a setup I won't get the benefit of. The Speedtech kit with uppers and lowers and the QA1 coil overs is probably more than I need but I think it will solve my steering stability issues, though I don't think I really need the QA1 coil overs?

I'm a little unsure about having extra caster built into the upper or lower CAs. I've read in some places that one or the other can cause fender clearance issues?? I need to get some solid info on that.

I know the aftermarket arms will be a big improvement but still unsure of which to go with.
Thanks
