The red one was pretty basic. Bigger tires and wheels. H&R springs, Sam's rear bar and Ford Motorsports front Shelby Bar. Custom Bilstein shocks on all four corners. rears are single adjustable. The car had a major mid corner push and almost no development. Every run in the car was different from the last. :)
Not sure about next year yet.
Prepped 2007 Shelby?
Prepped 5.0 GT?
or maybe STX 85 Mustang LX
Hey, don't forget about the super top secret, custom engineered, rumpty-rump tune. ;)
