Help me with alignment specs

[Harry Da Hamster]

I need to keep my 08 E90 M3 alignment specs within factory range to be legal to register here in Hawaii. I found the following factory specs in the attachment here on the forum but there's quite a range in those specs. I was curious if someone could help me with where within that range i should be for aggressive street driving. If i'm not mistaken, i would probably want as much camber as possible with as little toe as possible? Is this correct?

Strange that any registration agency would care less what your alignment specs are, but anyway...

You have a pretty broad "stock" range there. Pull the front alignment pins and you might get to the upper limit of -1.5*. The rear camber upper limit says its -2.0*. The E9xs don't need huge rear camber, and for the street I'd put it -1.5 to match the front. (I go -2.5*F w/ camber plates and -2.0*R and no probs w/ tire wear on street). Set the rear toe to 1/16" in and front to either neutral toe or 1/16" toe in.

Other folks may have different thoughts but this works well for me and should keep you in spec.

I think you have it about right, max camber and min toe in (within OEM spec) will tend to give the most grip and a better turn in.

Thanks folks.

Yep. Here in Hawaii we need a Vehicle safety inspection to get a registration. To pass vehicle inspection with a modified vehicle, we need to get a Reconstruction permit. Reconstruction permit will need alignment numbers within factory spec.
