If it were something i could chance back from at the flick of a switch, I would get that in a hear beat,
But the prospect of not having awd at all is crap, the difference in everyday grip of an awd and a rwd is unbeleivable.
If you are looking for a bit of arse out fun in your car, then get your self a 24mm rear anti roll bar, set it to the tightest setting and have her set up with whiteline camber adjustment bolts on the front with loads of negative camber,
And if your still not happy get yourslf a better rear diff, plated would be a good comprimise, or a two way for proper arse out!
Other wise, buy an auld skyline
Or do what i did,, (all of the above)
