Well Ron, this is my passion. I have been a PCA national instructor for 10 years. I run the PCA HPDE events here in the Seattle area for the last 7 years. I run Turn2 which is a lapping day company and I race in club racing. I put in over 50 track days this year and am running one on Saturday at our new track in Shelton Wa.
I used to track the GT40 but it has a lot of under steer that I have been trying to resolve. I currently run an FR500S mustang challenge car. It's so much fun! The 40 still gives me the biggest thrills though.
