Question. Small case 4.10 lsd fits on 325 is?

[Groove_D]

Oh well at least i got a spare one. I paid only $140 CDN for it. Originally i was only going to use it at the track but now i'm lazy to take it out.

Ok i put the diff in, i don't feel any difference in acceleration. It revs 500 rpm higher at the highway speed. Besides that no difference.

You'll feel a big difference in acceleration when it pops.

I'm 99% positive that the axleshafts on the at least the 318is are exactly the same as the M20 cars.

I agree with you on the length issue though. The small case diff has the same flange to flange width as the med case.

looks like part number 33211226901 covers everything except the 316

Yeah, the ABS axle shafts are the same between the 325i, M42 318i/s, and M3.

The flange-to-flange distance between diffs is definitely the same. However the small case diff has more distance to make up so the axles flanges are longer to account for the narrower case.

same reason they offer two types of axelshafts... 325i/m3/324td gets the bling heavy duty stuff, 316-320 gets the weaksauce driveline..I could be wrong but I don't thing the overall lenght changes, just the beefyness of the part.

Hm. I didn't realize there's THAT much play in the axles. Why would BMW offer two different diff output flange widths if it didn't make a difference?

[Julien]

axle shafts have a slip joint that allows enough play to fit either diff

[Collin]

Lol, if you can go from small case to medium case with no problem then why would it be a problem to go from medium to small?

More distance between pieces that should connect easily.

mattdk, your wrong ;)

anything e30, will work for another e30.

[Holland]

[Julien]

no, you need the 318 flanges to reach the 325 axels

*ahem*bullshit


maybe this is a on a 5 lug car? on a normal e30 you they are both plug and play

[Liam]

It will fit but it really is not the best choice for an M20 powered car.

[Groove_D]

I haven't bought it yet, thinking about. Was the mod worth it?
