To tell the truth...I was really worried. I had been to a few track days as a passenger, and ridden a few bike track days, but this was to be my first as a driver.
Having done a lot of the prep work myself, I was also worried that the car would not be up to it!

I went with a group of mates, one of which was driving a TVR 350C. I probably had one of the oldest anf slowest cars at the event, but hey, it was excellent fun. At the end of the day I certainly wasnt the slowest. A few cars threw in the towell, but everyone had great fun.
I did learn a lot about the limits of my car, and my ability.
I need new front tyres, and much MUCH better suspension, having run on standard shocks and springs! (new ones, but still stock!) I have Black Diamond brakes (drilled and grooved) which seemed to work well.
One big learning curve!
Do not stay in second gear at 7000rmp for a series of 3 turns! It causes a LOT of oil to reach the air intake and into the cylinders! (oops) After a lap it seemed to burn off and resume normal duty!
GO FOR IT.. you will not regret it!
