You will regret it if you do this.

Honestly, since I've done track days and autocross with a square setup, you really need to change something before you just slap these wheels/tires on and hit the track. I don't think you would be happy with a "compromise" alignment solution to make this setup work.

OK robinson, you have a square set up on a 2004 and you track, not autocross. Fantastic, I would like to hear from you on your set up as its Relavent. Lets bring this back to the intended purpose of my post.

AS A STARTING POINT, what alignment do YOU recommend based on what you have? I AGAIN intend to move to an adjustable coilover and front swaybar. I am simply trying to move up the time line of dialing in the car. I spent 4 years finding my set up on the m3. Just looking for a good starting set up.

Thank you.

Well...I don't track anymore, but I used to run with a large front sway bar on full stiff, no rear bar, and lots of neg camber front and rear, zero toe front and about 1/8 in toe in rear.

For you, I'd go with more rear neg camber, whatever you can get, and maybe -1 deg front camber.

What you need to do is balance out the added front grip. Removing the rear bar is/was not smart without a corresponding chagne to the rear spring rate, so I'd leave that alone, but as a last resort it will result in more rear traction, with less rear roll stiffness.

I was also thinking a slight toe in for the rear might help??

I track on a non-stagger setup with stock suspension.

As for understeer, alignment alone will change that.

Most s2k challenge guys run non-staggered tires; there's not really any correlation between having coils and running non-staggered tires.

A common "proven" setup is non-staggered tires, coils with non-staggered spring rates, and a large rear spoiler.

toe in rear will help a bit .
