Default Troubleshoot alignment specs after M3 control arm install - 01-19-2014, 09:26 PM

I had M3 control arms installed today and the strut pins were removed. Alignment was done as well.

My alignment was maxed out around 1.2' right and 1.0' left. Is there a way to get more out of it?

Can you physically push in the top of the strut in (towards the engine) to create more camber?

Here are the specs from the alignment sheet

Front:
Camber -1.24' / -1.04'
Toe 0.13 / 0.12

Rear
Camber -1.90 / -1.85'
Toe 0.15 / 0.14

Total Toe 0.29'
Thrust Angle 0.01'

Yes, push the top of the strut toward the engine for what another .3* negative camber?

Like said above, push struts toward engine bay to get a little more camber, but to get a lot more, you will need camber plates. You can get -3 to -3.5deg or more with plates and the M3 control arms.

If I loosen the top 3 strut bolts and push in, can this be done while the suspension is loaded?

No, I don't think it can be, or at least it wont be easy at all. You can just put a jack under it real quick and do it with the tires still on, doesn't take long

Can you describe this procedure?

I'm thinking you loosen the 3 nuts, jack up one side, push in at the top of the strut tower or at the top of the tire, and then tighten the nuts, lower car.

Does that sound right?

Exactly right, except jack the car up before loosening the nuts. I find it easiest to push at the top of the strut if you can reach under the wheel well. Might be easiest with a 2nd set of hands.

This is what I did. Crack all bolts @ top of strut tower, jack front of car and place on stands. Use both hands to break seal on top of strut tower. Mine was jammed. Push down and towards the engine bay. Pull up on strut tower with one hand and tighten nuts until secure. Lower car and torque to spec.

Note, the whole thing will only move over like 6mm or so. Its not much visually.
