Rowan,

are these the only gear ratios homolgated for Group A Commodores or were there others?

Also, what diff ratios were homologated for Group A Commodores?

Hi Rowan,
Yes interested in a gearset, belive there were two different size gears made,early box's had the smaller gears and later box's had larger ones, not sure if they are interchangable?
Do you know what sets you would be getting made?
Also the Getrag motorsport steel syncros are now impossible to buy, if there was enough interest it could be worth getting some sets of these made as well.

Hi Brett,

I'm off to QR today for the BIANTE TCM and won't be back until next Wednesday. I will follow-up then.

Gear sets are the same but you have to machine the early casing (sand cast) to fit.

Will look into the syncros.

Rowan I believe the BMW g'box is the same. The steel synchros are avail from BMW motorsport but horrendously expensive - about $500 ea.
There may be a wider market for the steel synchro's than just locally. I think I've got some spare steel synchro's if you need a sample...
