I certainly wouldn't expect consumables to last the same running a 25 at MSR-C as they did when the my FTD was (and still is) a 29.

I was kind of blaming the excess tire wear on moving to 17's.
I used to easily get 2 to 2-1/2 weekends out of a set, but since I moved to 17's a set shaved to 4/32nds now last 1 to 1-1/2 weekends shaved to the same specs.

I also think that my new set is wearing a lot faster than the two older sets that I have.
Being the suspicious type, I find it interesting that the increased wear due to lower lap times comes right after the release of the "new" RA1.
Edit to add: The Spec Miata guys are seeing the same thing:

Of course I was getting five events out of a set of front brake pads and now just two.

If there aren't enough AI racers at the events, tire choice becomes irrelevant as no contingency is viable.Quote:

Does any of this REALLY matter?? I don't think NASA is going to sever ties with Toyo for AI anytime soon... Get as much life as you can with camber setting, tire pressure, flipping, praying, whatever...
I ran on take-off scrubs for the last 5 years, so I have NO clue how many weekends I will get on a set of RA1's. With MSR-H being wet, it was kinda hard to measure the wear...
After MSR-C we will see where I am. I'm hoping to get MSR-C and TWS on a set and go into Hallett with a fresh set and have them last until the end of the year... 2 sets over 5 or 6 weekends.
MSR-C is a bad place to judge tire wear. It is super smooth and easy on tires. The first year I raced CMC, we ran there 3 times (2005), out of 5 weekends, and I got a total of 7 weekends out of a set.
