I have driven an RCF both on and off track, it does well considering its power to weight. Speed wise it is no different than a Z, dont let the 470 hp fool you. It rides a little harsh on road, but that is the "F" suspension.
The only thing I really disliked about the RC was visibility over the hood on track. With a Z car you feel like you are sitting "in" the car. In the RCF I felt like I was sitting "on" the car.
