I don't use a lift, I'm working on these cars at the track...
Jack stands, wheels off pump them out.
Believe me there aint much profit in renting race cars. We mostly do it to get people into racing.
All of our cars get brand new redline after each school or race weekend.... We then recycle it into the tow rig...
Schools are WAY tougher on the cars than race weekends.
School track time can add up to about 3 hours a day, where race weekends its 1.5 hours... For the whole weekend! Plus the newby drivers beating the crud out of the clutch and brakes and tires....
Have fun!
