I have the Lowenhart 18" by 10 in rear and 18" by 8.5 in front. I had them on my old 1993 525i, but now I have a '98 750il, and I'm wondering whether to put them on it or sell them. Ihaven't even tried them and I'm curious if anyone could tell me if they'd fit right on.? Any help is kindly appreciated Thanks!!
