I did Oregon Raceway Park in 2015... we won the C Class, got 3rd overall I think...
I did PIR that fall. We built a crazy splitter that unbalanced the car and damaged the CV axle boots which kept us off the podium. I did a bunch of trackdays with it in 2017 but have sold the car to somone in Washington who is doing 24 Hours of Lemons I think.
