hi huys, well ive got a 2000 B18C7 setup in my 99 cxi and ive noticed the gearbox is starting to get a bit sloppy in gear changes (feals loose and ever so slight random crunching through some gears.

I was thinking of refreshing the box (syncros, bearings, seals and bushes) but i was also thinking of changing final drive too. to help with torque and 1/4 mile runs. but its the final drive is where im getting confused.

i know the JDM S80 is 4:7 but as for the aud ive been told both 4:4 and 4:7,
and b4 ppl say search, all i could find is jdm spec.

So can anyone please clarify the specs on the aud S80 and also would 4:9 be too short for daily driver with regular strip work too.. mind you i do get on the highway as well...

thanks heaps guys.
