Scot, you win the "Twist & Shout" award this week. No one said there was a "large perfomance issue" when comparing 6" vs 7" wheels. And no one said there was "...no change in performance" when going to lighter wheels. They are both incremental performance enhancements; neither of them is going to make your Fiero 2 or 3 seconds a lap faster.

It was said that the sidewall issue going from 6" to 7" inch was significant enough to cause possible reclassing issues, but going to 10lb less weight wheels was not a "great hunk faster". ie, the sidewall performance issue was constantly puffed up, and now the weight issue is being minimized. What will be done to protect that stash of 6" wheels?
