View Full Version : LF: 3.73 or similiar LSD for E30

04-27-2010, 09:47 AM
I am looking for a 3.73 or 3.64 (I dont know all the numbers of what is avail) rear diff for an E30 track car. Must be LSD and must be in good shape.
I have a 4.10 but is proving to be too short.
I am also looking for a front sub frame for an E30 for a friend as well.

pls email me at lancew at bellnet dot ca.

Are you the guy with the Red E30 that runs in G70?

I might have a subframe for you, but it is modified (reenforced brackets welded in)... if you are interested?

i am also looking for a diff of that ratio, has seemed hard to find so far. i havent had any luck, and have been looking for awhile.

Yes, I run in G70 and GT 4 and this year, I am planning on running in the GT Challenge series. My car has been rebuilt with an S52 with a light flywheel and it is spinning up a bit too quick for my liking with the 4.10. Plus I think I am going to run out of gearing on the back straight at Mosport althought I have not tested that yet.
I will take the re inforced sub frame. It is for a friend that is rebuilding a track car and he was going to reinforce it anyway. How much? I am going to Calibogie this weekend. Might be able to arrange to pick it up on my way through?

Any luck?

I've got a front subframe from a 1986 325 if you're still looking. Willing to let it go very cheap. I can get pics on request.

The subframe Lance is looking for is actually for me. I don't need pics but I would love you to measure it to make sure it is straight and the holes are square with each-other.
Please let me know how much you want. Feel free to PM or email me with any info you want.

I have 2 lsd's. The 3.73 is coming out, I think it's slipping around corners, and the 2.93 is going in. It's better for economy anyways, I'll just have to relearn the shift points.
