I’m getting my UC engineered for HQ front disc upgrade (machines down discs on torana stubs) and shortened rear diff (-30mm off BUF-BUF)

My engineer has given me the list of maximum track widths for all toranas (in theory +25mm from stock wheel track).
NCOP Max Track width:
Front 1473
Rear 1440

All info I have read online say the UC track should be:
Front 1415
Rear 1382
These are considerable less than -25mm from the NCOP list, is there something i’m missing?

I’m wanting to run 14x6 Gts rims with 4inch back space which would put my wheel track at
Front: 1420
Rear: 1400 (with diff shortened 30mm)

I’ve called Holden and was told they don’t have any track width records, can anyone help me prove (on paper) UC stock track width or explain to me why I have conflicting info.

I’ll try dig out some stock Uc rims and do some measuring over the weekend.

Thanks for any input.

Max track width is for L34 and A9X which had different offset wheels.

 

I think you'll find UC offset is pos 32 and those track measurements you have are correct..

Thanks for that mate,
Just a bit of extra info for anyone else I was given some measurements confirming the rear track, I will look into the front track soon.
