(e30 shafts). if you car is lowered you DO need e30 halfshafts when installing a larger 188mm lsd or diff. yes, ti shafts fit but not very well and because there is no margin for movement i would say it could cause severe damage. at the moment i have used the ti flanges and halfshafts. on full lock and slow speeds there is vibration at the rear. today i ordered re-manufactured e30 shafts and they only cost £95 each. so its worth getting it done. __________________ E36 3.0 M3 Cosmos Schwarz E36 1.8 318ti Cosmos Schwarz | | | 06-04-2007, 01:32 PM | #2 | Senior Member Join Date: May 2007 Location: Seattle, WA Posts: 402 | Thanks. I asked this question in your other diff thread. At least we know now. Time to source some more e30 parts before putting it in next weekend. __________________ 1997 332ti - Don't even ask. 2006 330i - ZPP/ZSP/ZCW/6sp/Nav/BT/H&R Sport 2011 E92 M3 | | | 06-04-2007, 01:54 PM | #3 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | I didn't notice any problems when I had stock halfshafts with my 3.46 LSD. __________________ 1998 (July) 318ti, 5-spd OEM Armrest Blaupunkt Heidelberg CD50 CD Player/Compact Drive MP3 Player Diamond Audio 5.25" rear speakers Navman ICN 530 GPS BMWALARM.COM (with comfort settings) after market alarm system Magnecor 8.5mm wires M-Z3 Shifter/Momo Knob Burlwood Dashboard Stromung Exhaust X-brace Racing Dynamics Front Strut Bar Carbonio C.A.I. 17" Rial Rims Vader Seats/Heated/Lumbar Support M-tech Steering Wheel/Front Sway Bar/Front & Rear Bumper Depos/w 6500K Angel Eyes/6000K HIDs Clear Corners M3 Mirrors UUC Light Weight Flywheel/M5 Clutch/M3 Clutch Slave E28 3.46 LSD/Mcoupe Cover/E30 Flanges & Halfshafts UUC S.S.

My car is lowered, can't say for sure how much. Cali-Ti had problems just mounting the diff, drive shaft was not mating up. I really don't remember if the halfshafts wer parallel or not. I did eventually swap to reman E30 halfshafts.

Currently, with the S52 motor installed, the driveshaft is sourced from an M Roadster. They kept the stock 3.45:1 diff at the time. That may or may not cause issues for me when I am replacing with the lsd. I was originally planning on installing a new e30 bushing kit on my 'ti half shafts. I am now thinking I should just get the complete E30 half shafts. I am lowered by probably 1.5"-2" in the rear. I really need the geometry of the rear to remain in tact, as I'm running very wide tires on 17x9's on the track. I defintiely have no room to move anything either inboard or outboard, wheel-wise. One weird thing is that this car has 40,000 miles on it since the S52 was installed, and that stock open diff is rock solid still. Also, this S52 has an intake, exhaust, power pulley, and Turner chip. So, it's putting out double the output of the stock 318ti motor. That's a true testiment to the longevity and built quality of the stock open diff internals! Thanks for the info, Cosmos. __________________ 1997 332ti - Don't even ask. 2006 330i - ZPP/ZSP/ZCW/6sp/Nav/BT/H&R Sport 2011 E92 M3 | | | 06-04-2007, 08:20 PM | #7 | Senior Member Join Date: Jan 2006 Location: lancashire, england Posts: 300 | Quote: Originally Posted by L84THSKY It seems there are few variables involved.

Thanks for the info, Cosmos. | driveshaft ,or propshaft, wont make any difference as long as its sized for a compact. all the e30, z3, ti diffs are the same length from the subframe mounting bolts to the driveshaft coupling. the differences are the length from the subframe mounting bolts to the rear of the diff (diff cover end) hence needing to do a bit of grinding or hammering, and the width, hence the need to change the halfshafts. when doing your swap and you change to shorter e30 halfshafts there will be no change to the rear track. there wouldnt be anyway, if you stayed with the std ti shafts, so that shows how much strain they would be under. __________________ E36 3.0 M3 Cosmos Schwarz E36 1.8 318ti Cosmos Schwarz | | | 06-06-2007, 02:45 AM | #9 | Senior Member Join Date: Jun 2006 Location: SOUTH Jersey Posts: 1,085 | so the stock E30 half shafts fit right in with no modifications? | | | 06-06-2007, 04:05 AM | #10 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | Yup, I have E30 halfshafts and a 188mm 3.46LSD case.

E30 halfshafts are longer than the TI. the only issue i encounter is the grooved side of the TI output flanges compared to the E30 which is shorter but still beefier enough to stick in. - both flanges stick out from the diff exactly the same lenght. - the groove for the locking circlip in the TI output flanges is located about 3/4 from output flange end. in E30 output flanges it's in the end of it. not actually a problem cause u can just push it all the way in. so, basically, E30 halfshaft are longer and will handle bigger stress than the original Ti's | | | 07-28-2007, 04:49 AM | #12 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | This debate has run it's course a very long time ago. The E30 flanges are longer, but the E30 diff is wider, so the shafts can stick in deeper. You can't compare how much the Ti flange sticks out, to the E30 flange, it doesn't work like that. It is true that E30 flanges will go in deeper than Ti flanges in an E30 diff, but isn't that obvious from comparing flanges? Use the E30 flanges in 188mm large case diffs.
