rear adjustable UCA vs LCA in STX
 

I want to keep the ride height independent from the camber. UCA's are nearly double the price of LCA's (Racer X ). It seems that both achieve the same thing. What am I missing?

Just get the lowers and you will be set if that's the route you want to go. I am on the stock ones right now, found that at the camber I wanted, set by ride height, it was where I wanted in height and camber. Just used front camber plates to dial in the rest of the car.

I'll hold off on them till the rest suspension is in place and see if they are even needed. I just wondered, in STX context, why anybody would get the upper arms, since they are way more $$$.
