Honestly, I would go with a Wavetrac LSD, it's a helical LSD and doesn't use any wearing parts like clutches and Wavetrac says they are maintenance free, as they only use gears. There also other benefits of the Wavetrac design but I don't fully understand them. Honestly, diffsonline.com with a Wavetrac unit is the best bet.

Ya I quickly realized that a swap was a no go
Doesn't work; diffs online has some nice options
Really eyeing a 3.38, just curious how big of a change it would see over the stock 3.15
I had a 3.38 with upgraded clutches for 40% lock up in my e36, different car, it ripped tho |
I'm not really sure of anyone changing their final drive ratio. I've been told the 3.15 stock rear is actually pretty damn good for acceleration.
