the GTR is not 4wd, 4wd is for trucks with LOCKING DIFFS. the skyline has the nissan ATESSA torque biasing system. you can pull a fuse for the r34 and disable the entire front diff making the car entirely rwd. 4wd means all 4 wheels have equal power going to them at all times. which is usually why trucks have a botton you have to push to lock the diffs. because if you drive around in 4wd mode all the time you'd notice how the car/trucks likes to hop in sharp turns or just going around corners because the outside wheel wants to turn faster than the inside one.
