I have an m6 SS, would I be able to swap a lsd from a i4/v6 manual into my car without much modifications? Diff went out and am planning on selling the car anyways, just want a cheaper replacement than a SS lsd to get the car moving.

Thanks! I feel that handling is now much more confident, when the rear wheels push a whole car inwards, since now power is distributed much more evenly. Talking about a more aggressive ride ofc. In the city during normal, calm driving, can't feel the difference.

Waiting for the winter, some benefits should be noticeable then too.

According to the table in the first post, M6 SS is 3.73 whereas the AT/MT in i4/v6 diffs are 3.27.

Just wanted to pop in here, and say that the 3.73:1 LSD is a great upgrade for the V6 1LE. It's hard to find the 3.73:1 w/ cooler but other than that it's straight plug and play (you need to swap in your axle stubs though). Makes the gearing basically perfect (2nd gear goes to around ~62 mph).

Ive actually wondered that. Thank you for letting us know.

Yep, makes gearing basically perfect for a much lower torque, higher revving engine. Here's the speed in-gear with stock tires:


7,200 rpm stock redline, 3.27:1 (ew):

1. 41.1 mph
2. 69.9 mph
3. 100.5 mph
4. 134.9 mph
5. 180.8 mph
6. 241.1 mph

7,200 rpm stock redline, 3.73:1:

1. 36.0 mph
2. 61.1 mph
3. 88.0 mph
4. 118.2 mph
5. 158.4 mph
6. 211.2 mph

7,500 rpm tuned redline, 3.73:1:

1. 37.5 mph
2. 63.7 mph
3. 91.7 mph
4. 123.1 mph
5. 165.0 mph
6. 220.0 mph
