You gotta ask your self some very hard questions.
1. If something happens to your FE are you prepared to pay for the damages?
2. Do you know how do your own maintenance? Prep your vehicle to take to the track? Change all of your fluids? Bleed Brakes, Change Brake Pads, Rebuild Calipers, change your radiator fluid (some tracks do not want any antifreeze in the system - water only...just in case) there is more....
3. Tires, Rims are an issue. Do you want to track and street on the same set?
4. Do not ever allow an instructor to drive your car unless you bring a waiver for them to sign...Accidents do happen. I was burnt once.
The schools that i know of are as follows: Viper Days (BYOC), NASA HPDE (BYOC), Bondurant, Bertlose (spelling??), Skip Barber, Parump, Miller, Mid Ohio, Road Atlanta (Panoz), Summit Point (BYOC)....
Easiest way to find out is go to the tracks website...
Main Page - Trackpedia
Some have driving schools with cars others do not. On the schedule it should show driving clubs where you can bring your own & have an instructor in your car with you...
Most important...Find something that works for you. Have fun, be safe, always drive within your limits, if you know them....
