Post adjustable UCA install - are these correct
My SPC arms offer the most and easiest adjustment without removal.
Totally agree! I have your SPC UCA's on my car and I
LOVE them. I think they're even easier to adjust than using the stock eccentric bolts. :thumbsup:
But, not everyone needs them. For the average street car that range of adjustment is probably overkill, you can get what you need out of a set of non-adjustable tubular UCA's that have the caster already built in and just rely on the eccentric bolts for the alignment. That makes the whole alignment process a little easier because you only have to work with the eccentrics and not the arms themselves. And I've found a lot of alignment places don't want to touch parts like the SPC UCA's, they don't want to assume the liability. Which isn't a big deal if you do your own alignments like I do now, but for the guy that has a street car and a basic alignment and who just wants to take it down to the local tire shop, it can make life unnecessarily difficult.
To me, if you're going to run around on a set of 15" rims with BFG TA's up front you don't need something like the SPC UCA's. If you're running 15's then you're running 225's or 235's up front at the most, and if you run +3* or +4* of caster and -.5* of camber it'll be great. Now, if you're running 18" rims and 275's up front I've found that I want more like +6.5* of caster and more like -1* camber to tame those tires, which means the non-adjustable UCA's won't cut it. But I'm doing my own alignments and my car isn't exactly using a typical street car set up.
