Options on my car

Brian993 · Brian993's Garage

I just looked up the options in my car on pcar.com and I found I have amongst 10 others, these two options:

M220: Locking diffential 40%
M224: Automatic limited slip differntial

My question is what are there uses and benfits?

I know they are mechanical and actuated by the drive train, outside of that, no idea.

Goto the last thread (or is it the first) ever on Pelican Parts 911 BBS. It has some interesting information on these options.

Sorry. I'm still learning how to use this board. Here's the link:

limited slip differential post

Brian, I am not sure what "automatic ltd.slip" is, (they all work automatically when needed), maybe someone with more knowledge about the modern cars will chime in here.

40% LSD is what the factory puts in diff and is what you want on the street. Every differential, (except maybe drag cars), must have a certain amount of "slip", ie. allows one rear wheel to travel at different speed than the other, otherwise rear tires would be scrubbing and fighting each other every time you turn. If a car does not have ltd.slip, (one wheel wonder), and only one wheel spins on ice while other one stands still, that would be 100% slip. (One side is getting 100% of torque, other 0%). A 40% LSD means that maximum "slip" is 40%, left/right.(Or vice/versa). Hope that helps. It is definitely a desirable option on your car, w/ HP it has.

Also, Where is the web-site where you looked up your options? I tried pcar.com, didn't work for me. Thanks.
