Thanks for the feedback. At some point in the future I want to upgrade my wheels and I really like the F430 rims. I was checking eBay and when I did a search for F430 wheels these 458 rims came up. I was skeptical they would fit and appreciate it that you were able to confirm.
Cheng- The Scud wheels will fit the 360. Fronts are 1/2" wider than F430 wheels and you could get some rubbing at full lock and full suspension deflection, but only rarely. Like Mark said, they also made F430 Scud look-alike wheels that are the same 7.5" width as the OEM F430 wheels.
I'm just keepin the options open. I saw a nice 2004 360 six speed manual a few days ago with a reasonable price. The 430 6 speeds in red are so hard to come by! I can't believe Spring is just around the corner! thx for response!
