NASA has changed the spec tire for the spec 944 class to the new Toyo RR from the RA1 for 2013.
I believe the rules of NASA are the same as our SP1.
Question is, are we to use the new RR tire for SP1? Can we use either the RR or RA1?
sebring is around the corner so I need to order tires soon.

PCA will answer this question. 944 Cup does not have control over SP1 rules.
