Ok, I'm thinking of adding the RX-7 to the list of cars to be considered for a move to a lower class by writing an "official" letter.

So...if we WERE to be moved to ITB, lets look at the issues.

1- Wheels. No more 7" wide rims. The often used sizes on the 7" rim are 225/50-13 and 225/45-13. Some 205/60-13s as well. So, on a 6" wide rim, will these tires work? Or will we need to look at smaller sizes. No matter what, we won't be presenting the same footprint as we are now. Anyone car to guess a potential time loss? (Percentage)

2- Weight. They (the ITAC and therefore, the CR will never consider it without a weight change. Just for the record, at the 2003 ARRCs, the IT-7s were about 3.5 seconds off the fast ITA guys, and about a second faster than the ITB guys. So, keeping in mind the performance loss due to the wheel change, what weight should I suggest as a fair number??
