Thanks! great information guys. It just occurred to me that that one of the reasons I asked is what 986roadster said. I saw a 987 last week with 19's (sport design wheel I think) and it did look a bit out of proportion for some reason but couldn't quite place it at the time. But now that you mention it, you're right, just a touch too big.
Lil bastard: thanks. Didn't even think about the increased tire costs. I don't have my box yet, but when I do, I'm fairly certain I'm gonna go through some tires
Thanks again. Keep 'em coming. But sounds like 18 is a nice compromise--keeping in mind the tire size issue, but sounds like law of diminishing returns as you go any larger.
