@ Marty- The
ExtReme subframe was inspired by many things, including more front tire width with good steering angle, the quest for perfect geometry numbers, and the ability for non Corvette cars to start winning the bigger races.

The new system will drive just as well on the street as the Pro Touring subframes but they will be on "kill" mode at the track. It would be too lengthy to type everything that makes this subframe so great, I hope while you're shopping around you'll take the time to call us and ask for more info. For first hand experience Blake was the key designer, Roger has it in his car, and for an outside opinion call Ron Sutton since he helped optimize the whole package for any suspension strategy.
@Lance- Thanks! Roger is like a kid at Christmas time so far.
@AJ- In the beginning there was talk among the salesmen about trade in value if you already have a Pro Touring subframe, but I'm in marketing and am out of the loop on the sales end so I don't know if that's in effect or the details. Roger is our sales manager so I'd suggest you call and chat with him about it all. 435.628.4300
