yeah....I was just about to go that route...I had a ZO6 I was going to turn into a track car but realized how tricky that was going to be. Think it was going to be about $20,000 just to get a cage put in due to the aluminum chassis.
Spring Mountain is a Radical dealer so they have all the techs and parts there to support the car....so between that and the pure speed of it it was a no brainer for me. Love to see your C5R. any pics?
