I had 8,5x18 Wiesman MST wheels on the convertible. The thing wouldn't get past 210 km/h on the Autobahn. The ride was awfull and the tires very expensive! I changed back to BBS 16 inch split rims and regained my top speed (easily 240 km/h) and acceleration.
My fenders were heavily modified to accept the wider wheels. Especially at the back it's very difficult to roll the fenders.
Don't go bigger than 17 inch and take the BBS RS-II's. They look awesome. Don't sell the Sport Evo wheels. Sport tend to be worth more in STANDARD form (you're a dealer so you will probably know this).
Tale: most Evo's only have the wider fenders at the drivers side, when production started the passenger fenders where not available! (according to Sport Evo GOD James Abbott).
P.s. Not a member of the E30 M3 SIG anymore?
