What do you mean by this? Basically this thread sums up a few things about spc upper control arms & bc racing coilovers.

SPC UCA
-Don't change ride height.
- Because they are thicker & taller, tucking tire = hitting in a few places
- Limits of ball joint are reached when running at a very low ride height (tucking tire).
- Don't work well with RCA's because of hitting issues but depending on how much tire you plan on tucking, you will always run into this problem no matter what UCA you run.

BC Racing Coils
- Unable to tuck front tires w/o use of RCA's
- Rears are able to tuck tires w/o use of RCA's

wow, I was on HKS Hipermax LS with RCA but holy crap, never realized how angled the upper control arm must have been...

I guess you can go lower with roll center adjusters, but most likely your upper arm will start hitting the top of the wheel well even more.

also, you might want to be careful with that cotter pin...looks like its hitting your tires (last pic)

i dont think the pin would scrape the tire since it moves with the whole suspension/whee/tire.

interesting how steep of the angle is on a lowered car lol. now im thinking.. what if there was a slight angle on the UCA where the balljoint is.. so that the mounting area + the spindle thing are parallel to eachother. would that be beneficial? i might give a tiny bit extra clearance. but obviously dont just go out n hammer the UCA lol... hopefully FIGs has something in mind hint hint

I am looking into buying something to correct my camber and spc was one of my choices without beeing too expensive. I wonder if figs has anything in store for uca's..

What is everyones experience with spc rear camber correction?

i have both the front and rear SPC and they both work well...... bottom line here is if you are dumped it will put any UCA at an extreme angle..... this is not a specific SPC problem (although the extra banging IS a SPC problem)


what our cars need is an option for a shorter knuckle OR someone could go and convert the front suspension into a mcphearson setup and eliminate the UCA all together

For our lowered cars we need control arms that angle down to be parallel to the top of the spindle. That way the ball joint would be straight and under less stress....if figs ever makes a set im buying.

My fronts could easily tuck tires and im on BC "Extreme Low Spec" coils.

Heres how they sit out of the box, no adjustments made, springs havent even settled.
