Rear camber adjustment
 
So I recently got my car aligned for the first time, rear camber was about -3.2 and -3.8 on the left and right rear respectively. Does this seem like a pretty drastic difference?

Are there camber bolts available to help with this difference? Not really in the position right now to buy new control arms.

There are bolt/bushing inserts but they're a lot more expensive than bolts for the front suspension.

How low are you? That's a lot of negative camber. Were you still able to get your rear toe where you wanted it.

There are eccentric bushing for rear lca camber adjustment but it's PITA to adjust using those.
Just get adjustable aftermarket LCA. Cheapest ones like SPC/Whiteline/Eibach are not that expensive if you factor in pay needed for work to adjust using press-in bushings.
Camber bolts are available only for front.

That's "hella" different, but actually pretty common on this car. Mine was just as lop sided from the factory at stock height.

If you're going to slam your car, it's probably a good idea to get some camber adjustment if you dont like to waste money and wearing the inside of your tires prematurely.

Pretty low. Maybe like a 3 inch drop from stock. TBH I didn't touch the height adjustment on the rear coils when I first installed my coilovers. Wasn't thinking the stock coil height for them would be this low lmao (first time messing with car suspensions ever :/). Oh and rear toe is fine according to my measurement print.

Will my camber become more positive after raising them? I feel like that'd make some sense geometrywise. I will probably be raising them this weekend.

Ack. Just when I thought I did enough research, did not know how messed up the rear would be after lowering. Thanks for the info...

Yeah, new car guy problems hahah. I had no intention of "slamming" the car when I first installed the coils - the preset height was just this low. I'm going to raise it when I have time.

Kiibiiin: if "preset" drop is more then 1" ("3 inch drop from stock"), i advise to reduce drop below that, as overlowering alters suspension geometry too much and then you'll need things like roll center adjustment parts, diff risers to lessen load on bearings, headlight beam adjustment and such. (In addition to greatly reduced daily driving practicality and reducing comfort. Our cars are already rather low stock, already with rather short shock bumpless travel. Reducing it too much is not worth it).

Thanks for your input man. I'll adjust it this weekend. I didn't really put much thought into how much strain it'd put on the geometry after installing them, figured preset height was the standard and it would have been okay to run after a simple alignment.:bonk: Live and learn I guess.

churchx 07-26-2017 10:33 AM

Or "preset" = "as shipped", and to reduce shipping package dimensions i's maximum lowered :)
Do remember to do alignment, when you'll adjust coilovers to planned height. After major changes like these it will change toe & camber.
P.S.
I'd still get rear LCA. It's not really that expensive. And camberbolts for front (if these coilovers don't have camber plate in set).

Yes, it will. You'll probably still have some imbalance from left to right.

asdf 07-26-2017 12:59 PM

don't forget that you'll have to get another alignment once you re-adjust the height.

i have seen some rear control arms for sale recently on the forums -- would suggest picking them up and installing before you re-adjust your height so that you only need to get a single alignment
