No different final drive

No i also discovered some people with a D14a4 having the 4.058 final drive and others the 4.250.I don't know where that difference is really.Maybe it has to do with cars from 1998 and 1997 they also have different brake discs ...

O yes, mayby the 98 EJ9 all got a bonus, since my D14A3 indeed has the 4.25. But confusing all around which ratios are which.

[nope] Hell how many times do I claim 4.250... I got 4.059! 2015, see previous page for a bit more info [/nope]
