I've looked around, and everything I've been seeing points to the 3.07 LS diff having been married up to the close-ratio dogleg tranny in stock trim. My car has a 3.07ls and a getrag 265 overdrive tranny. Info I've found on the subject states that a 3.25LS came installed on cars with the getrag 265. My question is: was my tranny or diff swapped at some point in time, or did some of the cars come with 3.07LS AND getrag 265 from the factory?

Thanks

A lot of the euro cars came with the 3.07 as standard Diffs. My 85 Euro had it. The 85's had the G265 as well.

my old '84 euro 635 had a G265 with 3.07 open diff and 10:1 motor. All us-spec 535's came with a 3.25 diff (G265 on '85 model, G260/6 on later models).

It could have been swapped, I suppose. My M535 originally had a close ratio dogleg transmission and it came with the 3.07 rear. However, that transmission went out at some point, and the previous owner swapped in a 265 overdrive transmission since he was able to find one with low miles for a good price.

This combination does make for pretty relaxed highway cruising (and good mileage, too) but I don't suppose it does much for my 0-60 times.

Actually, My 1985 M535i has O/D 265 Getrag with the 3.07LS Diff. It sure makes a good cruiser on the Freeway @ 80MPH. Since it's my daily driver, that's perfect. I also had Euro 535i with a C/R and 3.25LS which was nasty off the line. First, second and Third will spin the wheels and get the car sideways (Awesome)

I'm familliar with that site. I have learned quite a bit from it, but some of the info conflicts with what I have read elsewhere, (like the 3.07 diff being married up to a dogleg tranny, for instance)
Doesn't really matter to me, I was just curious. I took the 3.07 out last week and put in a 3.46--much better for the type of driving I like to do.

I also have read posts here, (and on M535i.org) that the M-tech suspension was an option on the M535i. M-tech suspension is not a listed option on the build sheet for my car, yet the M-Registry site makes this statement:

How is the E28 M535i's suspension different from that of the standard E28 5 Series?
The E28 M535i's basic suspension configuration is identical to that of other E28 5 Series models, with MacPherson struts in the front and a semi-trailing arm design in the rear. Standard on the M535i, however, is the M-Technic chassis package consisting of firmer Bilstein shocks, shorter springs and thicker anti-roll bars.

Anyone know for sure who's right?
