I want to get the 18in Millie Miglia Sport Evo's for my 92 325i, but i've been hearing a lot about them bending easily. What's the deal with em? Also, would going to 18s really make the ride that much worse? I allready have 16s w/ an M3 suspension. Also, if i did get 18s, would i have to adjust my spedo. if i used a 225/40/18? I heard that when ya go beyond the basic plus sizing that it causes your speedo to get out of whack. Thanks Eric
