pulling the fuse makes it 100% rear wheel drive until you refit the fuse.
you can make your car 2wd while driving along in 4wd. step 1, put your foot on the clutch while driving, step 2, turn the ignition off while your foots still on the clutch, step 3, turn ignition back on and foot off the clutch, now you will be in 2wd without having to pull the fuse out. to ensure your in 2wd the orange 4wd light will be lit on the dash. please note that this is only possible on the R32 GTR's. the car will automatically go back into 4wd mode when you bring the car to a complete stop.
hope some of you lucky GTR owners have learnt something new, happy sliding... B)
