Look at Dinan sway bar diameters. 27mm front and 22mm rear, stock sport front is 26 rear is 16 if I remember right. There is a reason. |
I looked up the rear sway bar specs, I think the rear 16 is the sport and 323ti, z3m has 19, which I think would be perfect. My tires also help balance things are with 205's front and 225 rear.
As for the fenders, I have seen ppl use the e46 front fenders grafted on, but I was just thinking buying some simple flairs and putting them on - not any time soon of course - I'll probably keep to smaller tires/wheels untill I am happy with my suspenstion/brakes misc things and finally add more power then the wider tires and bigger wheels will come into play.
