E90 Front Camber Adjustment with eccentric bolt

bimmermech123 · 02-01-2022, 01:45 PM

I recently got an alignment and I knocked out the alignment pins on the top of the strut mounts to get some camber adjustment. The front camber is still not even on both sides and the car pulls to the side with the least negative camber. Camber plates are an option but they are very expensive and are not ideal for street driven cars.

I am wondering if anyone has ever put an eccentric bolt where the front lower control arm bolts to the subframe and if it provided additional camber adjustment.

I would not do an eccentric.

You can add M3 lower arms for more camber or add camber plates too also add some. There might be some aftermarket mounts that are slotted too.

Did the alignment place move the struts evenly in the strut tower? how different are the sides?

Thanks for the reply. The tech moved the struts so that the camber would be as even as possible between the two sides. The front left camber is -0.58 and the front right is -0.50. The car pulls slightly to the right and these specs do seem to be the reason.

Why would an eccentric not work?

thats such a minimal difference and likely closer than most cars out there. Plus unless you have a huge difference; camber would not pull the car so thats not your issue. Though I would have added more negative camber if you were getting an alignment: it'll feel more solid and probably get better tire wear

You should look at the toe as it'll effect pulling side to side much more.
