someone i know said this might be true. If so, why?

Yea, they used a Viscous coupler for limited slip and the M3 and is rears are clutch packs. I prefer clutch style.:: PNW Crew ::

The only time I've heard of people preferring an IX diff is because the viscous type will not affect classing, while a clutch diff will change your class

Clutch type are better, but viscous don't wear out.
But a viscous doesn't work much better than a worn out clutch type.Comment

I wonder where this idea comes from? you must be thinking of the VC "differential" used in old VWs and other lower end AWD cars, where all the power had to be transferred through the VC and there was no gearing. the ix's diff isn't anything like these.Originally posted by O 16581 72452 5 View Post
mine seems to work just fine.. it's not like you'll be one legging it, and the VC can lockup up to 90%. of course I've never had a VC in a RWD car, but I can get the back end to break loose about as easy as anyone else here.Comment

What ratio's do ix diff's come in? If they have something close to 3.25, I'd want to go with that in my eta. If I swap one out for auto-x use that would step me back down to STS. It sucks being in STX just because of my factory diff.Comment

the lowest available is 3.64, but only on early euro models. later manuals got 3.91 and autos got 4.10Comment

One big problem with the viscous is it has to slip before it engages.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

it does, but it doesn't take much time to lock - less than a second. you aren't likely to notice it.Originally posted by joshh View PostComment

Yeah, theres no doubt the viscous is way better than an open diff. But a clutch or even a torsion is better than a viscous yet there are disadvantages to the clutch style. But they are only disadvantages to people that aren't serious about performance....like the noise created by the clutch style diff.
The delay in the viscous is noticable to me.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

One last 2 cents. Viscous couplings are inherently less efficient than a mechanical one. i.e. driveline power loss in automatic vs. manual transmissions.Comment
