1998 993 Cab wheels

Vehicle Information: Year: 1998; Body Type: Convertible; Total Mileage: 32000;

I am considering upgrading my stock 17" cup wheels to either the 18" Sport Classic II ( two piece)or the 18" 993 RS3 wheels which were stock on the 94 Turbo. I believe they are a three pice or two piece wheel. I like both type of wheels but don't know where I could find the three piece 18" cup type wheels and who made them. Questions: 1) Which set of wheels would be more reliable and enduring, the BBS made Sport Classic II or RS3?; 2) I have a white cabriolet and I like the chrome or polished look. WHat's your opinion about chrome wheels?; 3) I was thinking of 7.5 or 8" width wheels for front and 10" rears, any thoughts?Thanks for your assistance. Feel free to add any other comments you may have.
