Go for it.
New 'blood' is needed on track days.
If you have a car with any real power and performance, the track is the only place to explore the real potential of you and the motor.
Any professionally run day will go out of their way to welcome new boys (and girsl!).
Oh and obviously it's a good idea to take tuition!!
This way proven this weekend on a Noble day at Rockingham.
You wouldn't believe the number of people who shunned the 4 Instructors available. Fortunately they were often passed by those who did take advice
