There is no current league ran in Indy Region nor is national SCCA running a league. However, please look into the unofficial iRacing SCCA series being ran by Steve Ray for this season.

If enough were interested, I would be happy to look into creating a league for us. I had a blast the one season we did this. Please let me know!
