GC Suspension & Diff Uprgrade

Postby RyBj » Sat Feb 25, 2017 7:28 pm

Im in the process at the moment of purchasing some struts from a GH with plans to put bigger disks on, new callipers, super low springs and new shocks. Also possibly some camber tops. i need to know which are the best parts for the rebuild ie shocks, calliper and springs. I am also trying to find a diff to replace mine and im leaning towards a Borg Warner 78, does it fit without shortening it? im planning on running sigma turbo globes on the car to give an idea of fitment. Any tips or help will be greatly appreciated.

Best parts really depends on ur budget and extent of upgrade.......as for the diff......any decent diff needs to be shortened....... Unless u go for something weird like an S2000 or something

Any idea as to what parts fit to the sigma struts in order to upgrade them? What suspension will i have to install once ive got say a shortened BW78 in there?

Sure u can!!!!!!

But ull be running 200mm flares and a 165 tyre to makes it fit!!!

I remember doing some reading on for some time......the shortest BW78 I found was a Chrysler century.......ur best option for the least amount of work would be something of an Australian built car built at the same period of time..........look at Toyota corona (the avante was the l performance model) and the bluebird s3.....both ran bw asses (tho I don't know if it was a 78), both ran four stud wheel, and both had a similar width to the sigma

The hardtops are a little wider across the rear than the sedans but not heaps.
I run a stock width Scorpion diff with

16x8 +13 rims. I had to roll the lips but they fit fine.

and with Sigma turbo rims

This is what I would be looking at if I was you, same stud pattern and thread pitch, disc brakes and better hand brake :thumpsup:
Shame you are in WA as freight cost would be crazy as I have a complete Scorpion 10 bolt diff here, converted to suit Galant that I could part with.

As far as front end goes, VB-VR, I think, Commodore inserts suit and they offer the full range of dampers you could ever want.
Springs would be the usual suspects like King, Eibach, Pedders, Lovells and so on
