So I am planning to go to a track I havent ever been to on Friday night. My normal track is a 1/8th mile and I run a 15/63-65 depending on the conditions. The new to me track is around a 1/16th mile. It was recommended to run a 12/64-65. I dont have anything but a 15 driver, so could I go to like a 69-70 rear gear and be close? What do I need to do to be close gear wise other than change the driver?
