Another new beetle question. Spec line says allowed 16in wheels but the class limits the width to 6in. Where the hell do you find that? I've got some stock VW 16's here and they're 6.5in's. I briefley looked for 15x6's too, but couldn't find any. I'm sure i could get some steelie's but this is supposed to be road racing, not saturday night under the lights stuff.
