in real every day situations on the roads driving legally then there is no reason to have a rwd over fwd.
on a track it's better to be rwd or 4wd over fwd, purely as you can push round the track without losing steering the same, if a fwd car is spinning it's wheels, then it's not gripping well for steering. on the other hand it's less likely for a fwd car to have the rear overtake the front on a turning.
i reckon my xr2 is pretty good at keeping up with a scooby, grip is the main factor IMO.
