http://www.diffsonline.com has some good new and used stuff as well as info/specs.
how hard is swapping diffs? i remember taking one bolt out for 325is suspension install to lower it, hopefully its all fairly simple.

This is my next intended mod. A medium case 4.10lsd from a 325i or e30m3. I hate the lack of an LSD in tight auto-x turns

so looks like 4.27 is the highest, correct?

e9nine · « **Reply #19 on:** April 02, 2006, 03:58:23 PM »

4.45 from a Ti. Good luck finding one though

The 4.27 is the highest ratio on E30's. I just did a swap from 4.27 open diff to a 4.10 LSD.

The 318i cabrios, for some reason, had 4.27 gears. I think finding one with a LSD is hard to find. I'm putting in a 4.10 LSD out of a 325i. This is GREAT news that I don't have to swap out the flanges. Someone told me I did.

is there any diff between the medium 325 4.10 lsd or the 318 4.10 lsd??? cuz i wanna either get another stock 4.10 LSD or swap in something better:D

its not exactly better to swap in a medium case diff. it will weigh a little more and it will handle more power but unless your going to do extensive upgrades to your engine i.e. stroker, or turbo or somthing like that you wont need a medium case.
btw the 318 has a small case.

believe it or not an open diff is better for auto-x. for tight turns, I forget the radius, an open is better. BUT for like track and places w/ bigger turns than a parking lot, a LSD is better.

I beg to differ. My experience with auto-xing and open and limited slip cars proves the latter to be an advantage. 2 prevalent examples:
When steering with the throttle, you are able to get the rear-end to rotate better with an LSD.
Accelerating out of a tight turn with one tire spinning isn't sexy either :mad:

well you really don't want to be loosing traction in an auto-x, ie throttle steer or pegleg burnout, that is unless you aren't a mad JDM RHD D1 drifter yoooo

I feel using a LSD to make angle adjustments of the car would make the main diffrence in a auto-x

there is nothing wrong with loosing traction slightly as it has benefits,
for instance you can accelarate more keeping the rpms higher and have the tires slipping slightly, as you are getting more power into the ground vs. full grip and lower rpm�s

I am not talking of that kind of traction loss (mad JDM bla bla bla). If you auto-x and have never lost traction before, or think traction loss is a bad thing...I guess we have very different styles of driving.

Picture the front of your car as an axis of rotation, sometimes you have to use perfect rear wheel slip to rotate you car. The front acts like a pivot and the rear rotates the car based on the drivers input. This is where the LSD shines in auto-x. Believe it or not, with the right set up there are a lot of times where your rear wheels will spin faster than the front either on purpose or not.

I guess we all have different driving styles but I will once again position steering with the throttle as being better than using the wheel especially for RWD cars (what i am used to)

Peg leg burnout, you'll never be effective in auto-x with that style of driving, you probably misunderstood what I said in the prior post.

ohh well, I suck at explaining stuff but who cares. A little slipping is good like you said. I thought you were talking more mad drifting stuff though. I have always been told that the open will let you turn in a tighter radius b/c a LSD in a situation like that will spin due to the wheels being locked together. again I suck at explaining things sometimes but I may be wrong. Its just what I have been told forever.
