I agree with everyone. I wish I had painted the wheels a different color. They came flat black from the factory. I'm thinking of going with a dark grey color instead. I get no noise from the springs at all, surprisingly.
I paid $880 shipped for the wheels and $900 mounted/balanced for the tires. Had I went with a cheaper front tire and 555R, it would have $750 for tires.
These wheels aren't produced anymore. You can find them used in the $500-$700 range. The 10" weighed 3.6lbs less than my stock cobra wheel.
I went to a dyno day this weekend in Florida. There were 7 cobras there including mine. 5 of them had Saleens and 1 had fr500s. It was nice to have something different.
