A Drivers Ed is a 1 to 2 day event where you get 5 to 6 20-30 minuets out on the track. This is not a race so no timing. You can pass slower cars after getting a signal from the car in front. If you have not been signed off into an upper level you will be provided with an instructor while there is no speed limit if your instructor feels you are starting to get in over your head they will let you know and ask you to slow down. Prices vary greatly from club to club but expect to pay 150-300 a day depending on who you go with and what tack you are running on.
You will be put in a run group based on skill not car. Green is the entry level run group. When you are signed into the white run group you are permitted to run solo at any track. Red is the instructor run group.
The spec miata and spec RX-7 are both very well handling momentum race cars.
Seems like the colored groups are only geared to PCA, you may want to expand this question to get more responses.
The value of the car is an agreed value that is on the contract you sign when you rent the car.
Thank you for all your advice on improving this, will you be attending the Glen event April 21-22 with the BMW club?
Yes if you were to trailer your car in with your crew the price goes up very quickly. I have heard spec miata racers talking of over $1,000 for a weekend race.
