The standard reply is it is expensive. Being a CPA I was curious on exactly what is the cost for HPDE events My cost is based on 5 to 6 track weekends a year. Cost includes basic do it yourself self oil changes, pad and rotor replacements, and brake flush. First cost is depreciation assuming the vehicle is used at least 75%or more for track. I would estimate between $7,000 to $10,000. Then add track fees, track insurance, gas, hotel for one night and miscellaneous is approximately $1,000 to $1,300 per event. Repair cost tires, oil, etc. plus $2,500 contingency for auto repair and other parts Adding this all up and assuming 10 laps a session 8 sessions a weekend leaves a cost of approximately $40 to $50 per lap. I read somewhere that Indy cars cost $3,000 per lap so it is all relative. I assume that a GT3 cup car would easily cost $100 per lap.
