Thanks to Greg and Tyler I was fortunate enough to have been invited to the test day at Buttonwillow when these tires were tested.

The testing went like this. 1st session was with brand new RA-1 shaved. We got about 10 laps. Second session was with brand new RR tires unshaved and again about 10 laps.

We did not get any additional laps on the new tires.

The car I was driving was a borrowed car that was pushing badly with the new RA-1. We were not allowed to make any set up changes between sessions.

The second sessions was about 30 minutes later with the new RR tire. The car I was driving was 4 seconds faster. The new tire masked all the handling problems the car had with the RA-1. It was very predictable and easy to drive fast.

There were a couple of cars in the 3 hr. enduro that night that ran the RR tire. This car was hit on the opening lap of the race and ended up with about a 1/2" of toe in after contact. The drivers did not know this until the next morning. They were running pace with cars in class on Hoosiers.
The wear pattern on the tires did not indicate a toe problem even after 3 hours. Even though the car had a push situation from the toe problem.
This same car has run multiple enduros on this set of tires with great results.

I think we have a winner here guys!!!

As far as Nats go I believe Erik is on pole, Niel off pole, Tyler 3rd.
