I try lots of different ways(wheels coming out and turning base..etc), but just cant seems to get something that can travel at great speed and yet turn very well especially at 90 degrees. I'm entering the NRC RCX category...so am hoping to find a gd design that is efficient.

the best system for a rough surface rover is a 4 wheel drive, four wheel steering platform. I carry the clod buster RC truck in my hobby robotics store because it has been used successfully as a ready made base for robot controls.
The main problem with a classic car ( single axis drive, front steer) is that at speed if the front wheels turn sharp there is a serious dive and roll response. also in single axis drive at the hobby scale the drive (rear) wheels dont usually have a differential.
The problem with differential drive is that the inside wheel has to slow (or even reverse) to get a sharp turn. this limits the top speed.
If you can't afford/ manage a true four wheel drive you can get a better response out of two drive motors mounted at opposite corners with free turn wheels at the other corners.
