BMW conversions (e36) - please read
BMW conversions (e36) - please read Those who have done LSx conversions into BMW's, what are you using for half shafts? My differential, mounts, and trunkfloor are very strong but I had a cv joint blow up on a mildy hard 2-3 shift the other night. I was wondering what is out there in the aftermarket for these cars.

The stock shaft that I'm using is BMW PN 33211229235 which is used in the following cars:
1.9l Z3
318 Ti
LK=80MM/D=26MM

I blew my 318is right side outer CV. I just installed M3 rear axles. It also requires the M3 rear trailing arms. The axles themselves and the CV joints are substantially larger than the 318 items. I don't have any experience with them yet but they should last longer than the previous axles. Mine lasted me 4 months on 135K used axles. The rear M3 trailing arms I believe require M3 rear brakes. That means you should also upgrade the fronts to M3 spindles and brakes.
I could go with ///M Roadster shafts and trailing arms, but they are only 1mm thicker diameter than what I've got. Will that make enough difference? I'm thinking that I may just need to go with soemthing like this

As for front brakes/spindles I'm running e46 M3 rotors and Wilwood 4pistons and kept the stock spindles

It is not the shaft that is the important part. You need to see if the CV's are different in size. M3 are twice the size of the sedan/coupe CV joints. I don't know anything about the MRoadster axles. Maybe you can find a visual comparison on google.

Verdad Gallardo Just got off the phone with another e36/7 enthusiast who had some half shafts laying around from an e36/7 ///M car. We measured his against mine, and length is the same (non-M 6cyl cars have longer), however diameter on the wheel side is different and would require ///M trailing arms, hubs and wheel bearings. So if anyone comes across an e36/7 or e36/8 ///M car with front end damage let me know :-)

Joe,
Been waiting for this to happen with my car, now have ~20k miles on my conversion with no issues to the rear end or half shafts, I am running the big 210mm euro E36 differential setup though. Using standard M3 rear half shafts, no signs of wear since day one and I beat my car pretty hard. I did find a significant design flaw with the engine mounting setup that I am in the middle of redesigning.

They did them for $500 a pair (stubs) but they said they lost money on them. Yep they do all custom heat treated chromemolly axles. Just send them what you want to copy. The fit and finish is beautiful. It took forever to get them though....
I'll break everything else before the axles and CVs.
I'm using a "large" diff 3:23 LSD from a Euro EVO E36 M3 with a dual mount cover.

I'm thinking about doing the ls1 engine swap but trying to decide between an E36 and E46 chassis. I like the E46's looks, but I think the E36 is 200 lbs lighter. Will the swap work in an E46 chassis? Also, I'm toying with the idea of using the engine/charger/tranny from a 2003 cobra instead. Thoughts?
