The best combination would probably be slipper centre and rear, with open front, as it will give more predictable handling.
The torque split front to rear will really depend on how much is available from the engine. The front will reach its limit before the rear, so if you have lots of torque, then you may have to bias it to the rear to make the car driveable. The rear bias will tend to encourage power oversteer.
thanks mate, The guy from milner off road could of bulit me a suitable transfer box with a gripper diff built in but its worked out too expensive really.
im now wondering what the torque split is on a mt75 box? could there be a way of altering it? if so i could spin it round maybe, or a skyline gearbox? i think the centre diff is controlled by a hydraulic system?
theres got to be a way to do do this?
