Shocks/struts and springs install for DIY

[Nick325xiT 5spd]

My front springs (TCK 450lb, std. length, whatever that is...6"?) show signs of coil bind. My choices seem to be bottoming out on the bump stop or getting coil bind. I now set the compression on the front to very stiff to keep either from happening. I have a picture of me in a turn and the front right is really compressed, indicating 450lb spring are just not enough for this car. At VIR North, the transition to the north course requires full stiff to keep me from banging.

EDIT: I'm talking about an E46 M3.

Have you trimmed the bump stop?

Edit: And have you considered running stiffer springs?
