agreed, don't worry about the brakes at this point.

just go easy and have fun in the turns. there will be people there in automtic luxury-cars just driving the course for fun. you can go at your own pace and run as slow as you want... lots of people go very easy.

in refernce to the helmet, i think that policy is just written by whatever insurance carrier they have.

this is great fun... it's just about being able to drive your car on the track to see what that is all about. for others, it is a good time to practice
