I tell all my customers that want this type of car. "You can build a great street car OR a great race car. If you try to build both you end up with a slow race car and an uncomfortable street car!
You have to make too many compromises to get a "best of both world" setup. Suspension that works in a straight line and is adjustable doesn't like to turn, and one that turns doesn't like to transfer weight / have adjustments for track conditions. Just my $.02
