I had the Eibach Pro Kit springs installed on my 06 v6 coupe. The front went down just slightly over 1", and looks great. However, my mechanic says that he cannot get the castor in spec. I bought the camber kit, but he insists that that is not what is needed. Has anyone had this issue? If so, what was your solution?

 

Camber kit will take care of it. I had the same problem and my mechanic told me the same thing. Thats why you cant always believe mechanic's.

 

Camber kit is just that (adjusts camber)... you can by top strut mounts that allow caster and camber adjustments.

Dont worry about the caster.
If it is out of spec, it is not because of the lowering springs
but some major body/frame tweaking problem.
There is no real way to adjust the
'built in from the factory' caster setting
except for slotting mounting holes.
Unless you get camber/caster plated for the top of the struts.

 

Or you can cheat.

 

Thanks for the advice guys. I just thought it strange that now the car pulls to the right after the spring installation due to what I was told was the inability to get the caster into spec. This is a spare car, driven only by myself, and does nothing but highway miles mostly on the Garden State Parkway. It only has 16000 pampered miles, never in an accident, and I never remember even hitting a pothole. I have 17" GT takeoffs and rear stabilizer bar. Before this, it ran straight as an arrow. I'm bummed.

 

Thats not cheating, thats a factory approved
method described in the Workshop Manual....

 

Lowering itself will NOT change castor; camber (wheel angle) will change. Camber bolts will allow the camber to be adjusted to within specs.
Mine lowered 7/8" and camber bolts brought it in plenty; nothing changed with castor.

If you are having problems pulling to the right with stock bolts, something is wrong and that should be fixed first. Camber issues wouldn't affect pulling that much, especially dropping only 1".

 

Wheel Caster.
Castor Oil.

 

Again, thanks for all the advice. I received the Eibach camber bolts, and they are quite a bit smaller than the stock ones. I don't know if I would trust them for strength. I am intrigued by Pascal's method of elongating the holes in the strut. That seems to make a lot of sense. But before I do anything, I will bring it to another front end shop for another inspection and alignment for a second opinion.
