88 S4 (USA) with 2.54 Final Drive?
Hey guys,
It seems my somewhat new to me 88 S4 has 2.54 gears in it. This car is certainly a US spec car, as I have the original bill of sale. I also have just about all the maintenance records, however there is a gap from about 94-97.
Is it possible this car came from the factory with this ratio? Otherwise, where are the transmission / final drive numbers on the case?
....or am I just missing something painfully obvious

If you post your VIN# on this thread:
https://rennlist.com/forums/928-foru...8-79-a-53.html
and ask nicely, Rob Edwards or one of the other VIN gurus will run it and give you a list of the options associated with your car. It might have been an option from the factory or maybe your car came with an '89 transmission?

And 4th gear is not OD as far as I know. Should be 1:1, right?

My amateur eyeball of the speedo and tach readings says you have the longer-legged 2.20:1 final drive ratio.
I thoroughly enjoy the 2.54:1 in my 1989 car, especially when in traffic. For any serious touring though, I'd prefer the 2.20:1 you have in your car. I'm not ready to swap permanently, but would have no trouble putting a 1988 gearbox in while I had GB refresh the original 1989 box.
