    What are the pros and cons of a limited-slip diff?

    What are the advantages and disadvantages of a limited-slip differential? Does it make a difference in Winter?

    I can't think of any disadvantages of a LSD. It will send power to whicever wheel has the most traction and will definitely help in the winter.<p>Serg<p><i><br>What are the advantages and disadvantages of a limited-slip differential? Does it make a difference in Winter?<p></i><br>

    One disadvantage to LS

With a smooth right foot, you'll have much better traction with a LS diff.<br>

    It's worth doing

    <i><br>What are the advantages and disadvantages of a limited-slip differential? Does it make a difference in Winter?<br></i><p>I recently put an LSD in my 535i here in Atlanta, so I can't testify to its effectiveness in winter. However, I have driven my LSD-equipped '57 Chevy in snow when I lived in Spokane, WA for four years and Minot, ND for two. With studded tires, it was nearly unstoppable, while my (then) non-LSD BMW could barely get out of the driveway.<p>On the con side, you might see a bit more tire wear because of the scrubbing as you turn sharp corners, but it's worth it.<p>Overall, an LSD is definitely a good thing to have.<br>

    Re: It's worth doing

    if I'm correct, the '57 chevy would have used something called 'posi lock' which is different than limited slip differental, same principle though.<p>the limited slip will still allow both rear wheels to move relatively independantly of each other.<p><i><p>What are the advantages and disadvantages of a limited-slip differential?

Mom's Buick has "Dyna Ride". <br>

    It's not a '57 LSD. Other types of LSDs are...

    <i><br>if I'm correct, the '57 chevy would have used something called 'posi lock' which is different than limited slip differental, same principle though.<br></i><p>It's not a '57 LSD, it's out of a mid-70s Trans Am. Yep, it's a "Posi-traction." Ford had a ratcheting-type "Trac-Lock" diff, whereby the slower wheel would get all the power (i.e. the inside wheel in a turn), which could really screw up handling in a turn. If you were on a dragstrip, however, it was great. There are also cone-type LSDs, which are second only to the Torsen-type infinitely-variable-torque-split diff. Torsens (also made by Quaife) are VERY pricey, however ($750 for an American car, $1250-$2000 for a Euro car).
