Hey guys, I have a vs commodore, and i was wondering whyhave diff not irs. Is this factory or aftermarket? The com. Plate says its a gu4 axle is that factory?? Need to know asap thanks.
They had irs and solid axle. Gu4 is 3.08 diff ratio. Calais and I think some ss had IRS, others will correct mr on that
berlina has live axle standard. Usually S, SS, Acclaim, Calais, and Statesman has IRS, unless it was up-spec by the customer.
All Acclaim, including, FWIW, VR, came with IRS. If the car is badged as an Acclaim but doesn't have IRS, (+ ABS and SRS) it's a rebadged something else (most likely Executive). (I'm only guessing at the intent behind the Q.)
