So are the SPC not good in your opinion? I herd that Eibach's adjustable upper control arms are made by SPC... I'm up against a fence on what to install. I actually already purchased the Eibach's and currently waiting for delivery but I'm worried about how flimsy that bolt looks that connects the arm to the ball joint and had the fear that my 22" wheels might rub that lower ball joint.. But you say you can't even really tighten it... That doesn't sound good at all...
BTW, what do you mean the SPC are preset? It looked to me you could move the ball joint freely from positive to negative in order to adjust the camber...
I'm happy with them, they're built well and I haven't had any issues. The "problem" is that with my car lowered the nut on top of the UCA is above the wheel well liner and it's hard to get up in there to get it tight.
The camber is fully adjustable, the caster has specific values based on how the washer/plate is installed.
