Thanks for sharing your experiences Beltempo. That trackday drive seems to be a lot of fun and thrill. BTW why did you drive hood up? I thought the range of vision when driving hood down could be higher.
Do you have a roll bar? That I would consider as a first alternation before changing other stuff.
Please don't get me wrong I like and share your fun. But if you go over the curbs in an unlucky angle, and it must not be your fault, you would be glad to have a rollbar, the way this guy in the video below had one in "his" Mog, even if he obviously was an untrained driver, it can happen to everyone.
