Ring and pinion differences - R200 (not R200V) - and LSD's

[GTSBoy]

I might be wrong, but I thought the Z3X chassis diffs had CV joint input flange to the diff, like GTR, not like RWD R chassis.

I sold the Nismo LSD to Fatz for one of his fleet and am using a Cusco instead, this needs GTR stub axles which are made of whale tears judging by the price. For the 3.5 ratio I'm getting a set of gears from Neat, I'm also building a 3.7 for Winton just in case.

The 350Z conversion is not as simple or as good as you'd hope. The front mounting 'ears' on the diff case are not in the same position from a height point of view so you end up with the diff hanging down much lower than a 'normal' R200. This creates some dramas with driveshaft angles. A guy I know has this setup in his S14 and needed to get GTR driveshafts to make it work which are also made from whale tears so it ended up being a very expensive conversion. Although the gears from Neat are $2k for a set, it probably would have been a better option with the benefit of 20/20 hindsight.
