Eibach recommends a rear alignment/camber correction kit for their lowering spring kits. For those with their lowering springs installed and who have had an alignment, how far out of spec was the suspension in the rear after lowering.

 

It's out of spec, but not by much.

I think I have the data in here somewhere:
https://g35driver.com/forums/v36-brakes-suspension-wheels-tires/138579-my-morning-eibach.html

but in summary:

The camber spec for the rear (non 4WAS) is:
-1.33deg MIN
-0.83deg NOM
-0.33deg MAX

Lowered with best alignment, my camber came in at: -1.7 / -1.4
AFTER kit install, my camber came in at: -0.6 / -0.6

The TOE-IN spec is:
0.00 MIN
0.11" NOM
0.22" MAX

Lowered with best alignment, my toe came in at: 0.11 / 0.26
AFTER kit install, my toe-in came in at 0.15" / 0.12"

 

And that's using the Eibach parts?

 

What's the best place to buy these kits?

 

Yes

 

can you link us to the place where you purchased this kit? im having my springs put on soon and im curious

Just a note, the G35 camber arm doesn't look like the one in the Stillen catalog.

Picture of toe bolt installed:

 

I would think the rear would not even be out enough to worry about. The fronts will wear out faster because its dropped lower.

 

I think so too. But its probably more noticeable in the back only because the rear tire is wider. BTW, still no word on front alignment kit for the 07 sedan from Eibach/SPC.

 

Thanks for the info ..

 

So we'd want both the camber arm and toe bolt? I've only ordered the camber arm from Stillen, which has been on backorder for weeks.

 

You can wait to see what the toe looks like after camber kit installation. You may not need them. The catch is if you do need the toe bolts ... you will need another alignment after installation. Or if they are not very expensive, buy them just in case and sell them if you don't need them.

 

Eibach lists their alignment kit (PN 5.72260K) as having both camber and toe adjustment. That's the kit I ordered through Stillen. I wonder if Eibach mislabeled their own product.

 

I believe you are correct ... Eibach kits both together while SPC sells them a la carte.
