Here's a stupid idea: 18" diameter wheels with black lip to simulate 15"!

Not a stupid idea at all,on the right rim of course, I'm guessing a retro-rim
like wheel vintiques modded? Whatever, done well you'll have the right "across the
street" vibe, under scrutiny you can't hide it so just do a nice job of it.
There are very few sticky 15" rollers, and most are too small to look right on
your car. The cooper,it's mastercraft sibling ,& BFG T/A,are decent tires, but super
sticky they're not. The Ultra touring and Touring LSR a least come in "H" ratings
if you plan on that kind of speed, I believe the T/A's are pretty much "S" jobs.
Oh, you CAN buy repro Michelin MB's in 15" for competition action, if you
don't mind dropping 2+G's at coker tire !!
