Hi guys Will Z3 2.8L half shafts work with an E30 medium case diff in a 318Ti? They have different part numbers to E30 half shafts, but this is probably because the pulse rings are plastic etc. Cheers Dylan __________________ Supercharged 318Ti | | | 10-27-2010, 11:40 PM | #2 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | Quote: Originally Posted by denglish318ti Hi guys Will Z3 2.8L half shafts work with an E30 medium case diff in a 318Ti?

The 2.8L Z3 half shafts that I used came from a 97 2.8L, they are too long to fit with a medium case differential, but they would work with a small case diff or a Z3 diff. Actually the half shafts are approximately the same length as the ti shafts but they are beefier. The shaft diameter is larger (28mm versus 27mm for the ti) they use 86mm diameter medium case output flanges (80mm for the small case) and 10mm bolts (small case uses 8mm)... Also the splines do fit the ti hub the same way the e30 medium case half shaft fits the ti hub splines. __________________ Alpine Weiß 1995 318ti M50tu mostly stock, chip'd 413, AFE Intake. e36 M3 front brakes, e30 M3 rear calipers. e28 3.25 LSD + e30 axles.

I think it is because the 2.8 and M models have a wider rear track and therefore have longer shafts. Back to trying to get some second hand E30 ones in good condition! __________________ Supercharged 318Ti | | | 10-29-2010, 03:52 PM | #6 | Senior Member Join Date: Apr 2009 Location: Merritt Island, FL Posts: 351 | I do believe the attached picture should sum it up... BMW introduced a different style differential with the Z3 and I don't think that they were equipped with the 188mm medium case LSD's. From what I can tell (but not 100% sure) BMW got away from installing LSD's after ~1996ish with a few exceptions, the M3 being one of them. BMW either used Automatic Stability Control plus Traction ASC+T or a Torsen differential (similar to a Quaife). __________________ Alpine Weiß 1995 318ti M50tu mostly stock, chip'd 413, AFE Intake. e36 M3 front brakes, e30 M3 rear calipers. e28 3.25 LSD + e30 axles.

I know that the 2.8/3.0 trailing arms are not the same width as the ti but the 1.9 and the MZ3 trailing arms will bolt up and be the correct width. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM | | | 10-29-2010, 04:21 PM | #8 | Senior Member Join Date: Feb 2007 Location: Fl Posts: 1,353 | Quote: Originally Posted by spidertri I thought all Z3s (with the exception of the 1.9L maybe) had a LSD stock.

Better traction control since it will vary applied torque to the wheel that is loosing traction. Also I don't think that they have the 188mm cases, they are more narrow (similar to what is shown in the picture). __________________ Alpine Weiß 1995 318ti M50tu mostly stock, chip'd 413, AFE Intake. e36 M3 front brakes, e30 M3 rear calipers. e28 3.25 LSD + e30 axles.

I always thought the cases were the same. Where did that picture come from? Looks like some Z3'er doing the double eared diff mod, with that diff cover that hangs SUPER low. __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!
