A4 to m6 rear end swap help I have a 2000 z28 a4 85000 miles got a good deal on it because rear axle bearings were bad the guy said he had been driving it like that for a year and a half had thought of upgrading to a better rear end till I saw the price but just came across a used rear end out of a 98 m6 car which if I'm not mistaken will change my gears from 2.73 to 3.42 would this be a good swap they are both traction control cars so I think I'll be good on that my main concern is that I'm aware that there are two posi set ups which I think my current rear end would have the better of the two and the 98 does not thanks

I'm pretty sure the difference on the posi units is that the 98 will have a clutch style and the 00 will be a torsion style. IMO, don't be surprised if you just swap that M6 rear end in and it has gear whine. Common knowledge tells us that M6 rear ends tend to have a harder life than A4s. The stickys in here should tell you anything you want to know.
