They just .. look really heavy, and I don't think that look will match with the MSP very well. The MSP is about being light and agile -- those remind me of something that'd go on a silly SUV, bulky and sloooooow.
And a piece of advice .. If you got a wheel that size, you'd have to run a 35 series tire. And those make for a rough ride. Just something to take into consideration!
yeah, they do look too big and too heavy. are you set on chrome? i have heard nice things about the konig britelites (machined lip, polished elsewhere, painted spokes) light and not too busy. I prefer the stock wheels but to each his own, at the end of the day it is your car and if you like it that is all that matters.
