Alignment Issues after Coilover Install...

I just installed my BC coilovers along with the spc front adjustable a-arms and the rear camber kit and toe bolts...i went and got my alignment today and w/ the adjustment all the way out im still like 2 degrees off...i thought the point of buying the camber kits was to not have this alignment issue...

what do i need to do to get my alignment back into spec without changing the current stance of the G (really dont wanna raise it)...I just see alot of people w/ slammed G's round here how did yall go about fixing this issue? or do yall just have excessive tire wear...



Here's my specs:

Front: Left Front: Right
Actual Specified Range Actual Specified Range
-2.5 degree -1.3 to 0.3 degrees Camber -2.7 -1.3 to 0.3
9.6 9.6 Caster 9.2 7.3 to 8.8
0.04 0.02 Toe 0.05 0.00 to 0.08


Left: Rear Right: Rear
Actual Specified Range Actual Specified Range
-2.8 degree -2.0 to -1.0 Camber -2.5 -2.5
0.11 0.00 to 0.22 Toe 0.10 0.00 to 0.22

How low (vs stock) did you go? If you lower past a certian point, you can't go back 100% to stock alignment. I could be wrong...

Alignment arms have a limit. If yours are maxed out and you still are out of alignment then the only option is to leave it alone or raise the car.

As far as I know ALL camber kits cannot put a slammed car to 100% factory specs. I don't know if the OP is slammed though.

According to others with the SPC kit, it offers a max + camber adjustment of +2 degrees. HOWEVER you MUST install the included spacers on the hub, otherwise you'll only get a max of about +1 degrees on the a-arms themselves. Most people on the initial install don't put the spacers on (especially if a shop installed them) because it's much more labor intensive. So make sure you got those spacers installed as well, if not do so then return for another alignment.

You can't have best of both worlds in this situation.
Either raise the car up or live with the negative camber
I had to learn this the hard way..
Wasted money on multiple alignment jobs

like i said my boy didnt install the hub spacers when he did it so that should give me +2 degrees more and should fix the problem...

You'll get another 1 degree positive camber with adding the spacers, the arms themselves added 1 degree alone. You'll likely be closer to factory specs but if you're that low you may never be able to get completely back into spec. Like others have said, it's the tradeoff you get for a slammed stance. As long as you get close, you shouldn't have too much prob with excessive tire wear.

I have the SPC kit front and rear, did not install spacers in the front but i'm getting so much
tire wear in the back that I have replaced tires twice this year (see post below):

Do you have rear active steering on your car? because if you do I don't recommend dropping that much, cuz you can't adjust the toe in in the rear, the toe bolts just don't cut it.

The hub shims aren't really that hard to install. It takes a while, but it's pretty straight forward as long as you have some basic tools.

Yes, the hub spacers should give you more adjustability. I'm in the process of installing mine also, just waiting for some free time to do it. It's just annoying to install it yourself and then drive a couple miles to alignment shop with the alignment all out of wack.
