    Running into alignment issues

    Guest-only advertisement. Register or Log In now!
    Hey guys, I'm on BC coilovers, the car is sitting around 24.5 all the way around and the camber and toe are way off. I don't remember the front specs but the DR is at 2.9* of negative camber and the passenger side is at 1.7* and the total toe is around 1" off. the Eccentric bolts are maxed out and I can't get any more play out of them.. Any suggestions?

    You can shift the entire sub-frame towards the passenger side to net an even -2.3* camber each side. From there, you are limited by your upper control arms - you need adjustable upper control arms to dial back the negative camber. You will also be able to adjust toe at that point, if needed.

    The stock suspension is not very adjustable, so when you go low, all else the same, you get some unfavorable geometry.

    Bad thing is I have raised the car a couple of inches from when I got the thing, came with the BC's on it already. Is there a link on how to shift the subframe? I'm not so worried about the camber as I am the caster and toe. I will upload a pic of the rear results

    I was referring to adjusting the front end, btw.

    You can find some info on shifting the subframe by searching

    You need adjustable control arms. Subframe alignment will only do so much.

    wait wait. Your toe is off by an inch (hard to read, but over an inch of toe out is way way too much)? HOW? your toe should fully be within spec. something's bent or wrong here.

    forget the camber, that's by far the lesser concern. but yeah change ride height or adjustable uppers is the only way to fix that piece.

    and i can't see your caster as you only posted the rear... but i wouldn't stress caster very much (within reason).

    check for bent control arm. the toe adjustment was maxed out, not frozen right?

    and i would fix your camber, if you're just commuting, you're gonna burn the inside of your tires. just lift the car up more would be the quick fix (might screw with the coilover settings, not sure how the bc's work, but increasing height on nonadjustable perches will increase preload (bumpy/bad)). Personally i'd get the adjustable upper CArms.

    Bc's have separate spring preload and height adjustment.
