I cracked an oil pan on our pink car at Road Atlanta 2018 going over the outside curb at T5. I was coming down the esses gaining on a slower car who then got on the brakes way earlier than I anticipated. It was either run in to them, or dive off in to the grass track right. Chose the grass and ended up straddling the outside curbing thats on driver's right, right as you turn in. Heard a thud, immediately started looking back hoping there was no smoke, etc; car seemed fine and I continued on for the remainder of the stint. Came in for a driver change and we immediately noticed a puddle starting to form. The hit happened right at the drain plug and the threads were leaking.
Went over the curb here aiming for the grass/escape road
