The car originally came fitted with a H165 live axle rear end with an open centre 4.11:1 diff. It just had to go, the car is pushing 120Kw at the rear wheels and you just never knew which way the car would slide.
I am now running a 720 4WD front 4.875:1 ratio Nissan R180 LSD, fitted to the swapped out DR30 Skyline IRS setup. (Also have spare 4.6:1, 4.875 and 5.1:1 ratio crown wheel and pinions)
260Z rear R180 long nose housing
Skyline DR30 rear crossmember and trailing arms.
Skyline DR30 axles and CV half shafts
New bearings and shims
