78 Camaro upper control arms
I want to replace the upper control arm with tubular arms and rebuild the OE lowers.Summit has their brand/pair for less than 300.00 But they are not adjustable,is adjustablty something I need?

Nope. Camber and caster adjustment is done by shims between the arms and their brackets on the subframe, same as stock. The nuts are loosened, shims are added or subtracted as needed by dropping them over the bolts, then the nuts are tightened.
The adjustment is great for circle-track, but they run some rather extreme settings that would destroy street tires. Their settings can get so far from stock that shimming isn't adequate.

Thanks,I see alot of adjustable control arms but I've never had a reason to fool around with them.
