2nd Gen Firebird Control Arms - Again

[fastd]

does anyone know what the most caster i can get out of stock 1972 Firebird Formula upper control arms at -0.5 camber?

and what the most caster i can get from ptfb upper control arms at the same camber?

and finally, to install spc uca's, does there need to be any fender, body cutting to get to fit?

thanks in advance.

I am using SPC upper and lower arms for my 67 Firebird, they fit with no issues.For the money and adjustability they are in my opinion the best arms out there.

Spc uca's will not fit 2nd gens without some massaging.
I just bolted on the PTFB Uca's on before my last track day. I'm running +4 caster and -1.5 camberyppk with tons of adjustment left.
I noticed tons more grip on the road course and the ride on the streets is allot smoother. I've been told that the smooth ride is because of the free movement of the uca's bushings and the added caster.
