performance i have to pick and see which goes well with the car alone.....don't want to spend some much of my dollar fitting things that will make the car goes worst.
I have ride this m3 with an instructor over in BMW Performance Center in the States during FEB lapping its driver training course...and it feels just as good as right now..
as for springs..I want something alittle stiffer but not bouncing all the bumps on the road. I have ride on a porsche with sports springs..and it just hops on all the bumps...
