As a reminder, Onawa is an IHRA track. As such, we'll be using the IHRA 1/8th mile indexes. IHRA still lists the latest indexes on their site so check in there to see what yours is. And yes......we've added the new index for SS/AH.
We will have IHRA Index sheets available at the track for you to check, also. It would also help the tower out to have your index on the drivers side on qualifying runs.
