E92 M3 Suspension geometry

[jezrider]

Hi everyone,
A friend of mine has just purchased a Bilstein coilover kit for his e92 M3, with the intention of improving the standard set up for track day use.
I appreciate that a good quality coil over kit is not really just a bolt on modification and the geometry and ride height is therefor ecrucial to how the car handles.
Has anyone here dabbled with geometry and ride height settings for this car?

Cheers
