blows my mind... im interested in how each one works, and the effects of it on acceleration (lock unlock etc) for each of them....

would be a great wealth of knowledge to have in one place....


bueller?

Dude. Where's the young gun action? You have to know two-three times as much as the old guys do. That's the rule.


All limited slips consist of clutch mechanism(s) and a spring to hold the clutch(es) down. This way there is a lot of resistance to slipping. And it will slip when there is a lot of force telling it to, like when turning. And no slip (or very little) when your coming down the straightaway.

The difference between manufacturers is either quality (parts tolerancing and failure prevention) OR novelty (achieving the same effect a different way.) Not usually both.

The phantom grip isn't really a limited slip. It's positive traction. It locks both differentials when there is positive pressure coming from the pinion. And it unlocks when there isn't any pressure. They even sell spring kits on their site to be able to adjust responsiveness, i.e. how much pressure locks the diffs.

A limited slip, posi-trac, locked, or open differnetial drastically changes how you have to drive on the track. If you're used to powering hard through corners, then an improperly tuned Phantom Grip will literally make your car "undrivable." But maybe a locked diff would be ok, because then you just have to push hard enough to break the tires loose.

But now I'm past answering you question and I'm blabbering.
