Been doing a bit of groundwork at the back of the car. Cleaned up the new diff, now I need to locate and fit it to the chassis.
Being originally designed for a live rear axle the chassis has no fixing points for this independent set-up. Not sure how the half shafts will sit either, they may need cutting down to suit the new hub positions.
If you are wondering why I didn’t use the Omega diff, it was a 2 fold decision.
1. The Omega diff is not an lsd, and trying to find one is tricky and expensive
2. The Omega is wide, 10” wider than the Ginetta, and that’s just too much to chop out from each halfshaft.
The plus points for the Nissan lsd diff are, plentiful supply (from the drift scene!), cheap-ish, various low ratios and can run a cooler if necessary.
Anyhow, levelled the chassis, left to right and front to back, this took about 20 mins to do this properly, shimming it here and there. Then set about dummy setting out the rear wheels in the arches, running a plumb line down through the wheel centres.
This gave me the drop line and effective centre of the hubs/shafts. I projected this drop line accros the chassis and ensured I marked the chassis perpendicular to this projection. I started using the laser marker, but it ended up easier to see with string !!

The diff actually locates quite nicely toward the rear of the chassis and close to the cross rails, so it should be easy to fabricate a drop down support for the rear of the diff.


I need to fabricate the front diff cross-member first and make some nylon bushes. Once I get the nose supported and positioned I can then double check front/rear/left/right positioning and then get the rear of the diff supported and fabricated.
The diff cooler, if I run one, will be positioned later in the rear end build.
