Reading the post above about rubber tires used in 12th scale is a bad idea. Rubber tires does not have a more connected feel and it will make the cars harder to drive. If people struggle with 12th scale on foam tires, stay away from rubber tires! Pan cars are a special class that requires attention to the smallest detail. Once you get it the cars are very easy to drive. I love 12th scale and only want see foam tires. I do think the body styles need to improve from the wedge. The GT12 class is awesome and has done a great job with the bodies and helping 12th scale grow. Keep moving in that direction.
Just my .02 cents.
