Hi Simon,
Before I had the GTS Bilstein set up fitted I had the geometry always set with maximum negative camber on the rears and neutral balance and castor on the fronts in a more track biased setup.
The only downside is a slight tendency to camber steer on uneven surfaces but does give a more even tyre wear suggesting more rubber on the road more of the time. Plus I took the recomendation of the guys at the factory who say 2 bar allround makes it feel more planted.
How does it handle white lines? My QP tends to be a bit skitish when going over the them especially in the wet. Can't understand as my GTV doesn't even notice white lines.
