Sorry I wasent of any help.
James is telling me the 235 tire rule has really slowed you guys down. That is a lot of car on a small tire! The Corvettes really have worked on setup to make the 255 and 245 work on them.
Yup. We're about second slower now overall (driving the pee-piddily-diddily out of em), but those tires go away fast when your pushing em. And one set didnt last a full weekend (we corded two tires by end of Sundays qualifying (we started the weekend on stickers on Fri.)). Made for an eventful Sunday race.. we were just hoping to finish w/out a tire coming apart. We should have considered the extra tire wear and brought another set, but that would have been too smart
Not sure what the National cmc directors where thinking here (more cost to the racer in a class thats supposed to keep costs to a minimum).
Your right, it's going to take some time to figure out right set-up to make the cars work on these Miata tires.
ps. There are a lot of "knock off" cobra r wheels out there.. weights differ accordingly
