M3 E46 handling upgrades for track day use any adv
Discussion
I have used my m3 on a few track days now and had enormous fun but I need to improve the handling after driving the new noble 400 at Bedford and seeing just how quick you can take corners with the right setup. So far the choice is spax rsx coil overs, bilstein PSS9, or K&N. I am also having the ecu re-mapped and there is a bit of a dilemma there should I get it supper chipped or get it done by ray west or DMS automotive has any body out there had experience of either
