Whats the diff?

[Exidor]

Going for a shorter diff for the zed.
So, can anyone tell me the difference between
a 3.89 & 3.91 ratio. Apart from the obvious.

Apart from the obvious.

Not sure what else you want to know?

What's the difference between 3.73 and 3.91? One is slightly shorter..?

[Exidor]

Curious because of their very similar ratio.
Is one considered stronger.
Are the carriers different etc.

I'll just put my anorak back on.

[STEALTHY™]

Carriers are the same. Should also be the same strength, they've both be made out of the same material.

The only difference would be the normal difference's, but with such a small change, i doubt you'd notice either (i barely noticed an increase in acceleration going from 3.08 - 3.45s)

[danja]

If Diff Technics are anything to go by, 3.89's are for a Ford diff, and 3.91s are for a Commodore diff. VZ's diffs should all be M80's.
