Vt berlina wagon S1 5.0 + vn berlina sedan 5.0 man
hi all
Just picking brains regarding diff upgrades for the Vt s1 5.0
I got a Vt s1 berlina wagon 5.0
From my understanding I should have a m78 @3.08 ratio
My diff says 3.07 ratio
I uploaded a pic of tag on my diff
Is this a m80 diff I have?
It’s definitely a s1 97 Vt berlina wagon
I thought Vt s2 had the m80 3.07
Is the m76 a 3.07 or 3.08 diff?
Anyway looking to upgrade to 3.45
Heard that vl had the m78 in 3.45
Will these gears fit my diff?
Or can I get a 3.46 set to suit
If so is 3.45 worthwhile
Any info appreciated
Cheers

If it is a m80 then the bonus is 3.46 for it are way cheaper and more common than a vl 3.45 diff.
Some would argue/ say 3.73 would be the way to go ( wouldn't go more than that in an auto. Really depends on you and use .
If doing lots of highway kms then 3.45/ 3.46 ( if get for right price) a good compromise.

Cheers buddy good to know
Yeh strange though
Definitely a series 1 Vt
But diff tag definitely says 3.07?
So I’m guessing it’s a m80 cheeringThanks all
