looking for an LSD
 

I'm looking for an LSD ( Limited Slip Differential )

I noticed a lot of the track guy changed their stock LSD

anyone of you guys thinking of selling it !?

I'm phoenix

but i'm gonna spend my spring break in Denver if anyone over there has an LSD

Given the work required to install the thing, you might as well buy a much better aftermarket one. While the stock sport LSD is OK for most people, the real track guys think they're $hit. If you're just daily driving, then one could argue you don't need a LSD at all. And if you need one, you're better off installing a good one. Go big or go home!

is there a difference in torque or handling !?

but I also think I have heard its easier to put an aftermarket into a base unit, so a complete swap might be beneficial for him and the new recipient, as it would just be a bolt in for him.

Its on my list, but not just yet.

All the aftermarket limited slip diffs are designed to bolt right into the pumpkin of the base open differential without needing anything else. That is part of the reason I chose not to get the sport package LSD as I have my eyes on Quaife personally for performance, durability, and drivability.

So it's not a clean swap for an aftermarket option if you already have the sport LSD? What more does it entail then?

It is a clean swap - depending on what you get. You want to buy a aftermarket diff that has been designed as a replacement for the stock sport LSD. The Quaife unit was designed for the base model LSD and so to use that unit you would need the stub shafts from the base diff. Alex, since you are a track guy I would with the Carbonetics which will be a straight swap for the stock LSD.

So are you all saying I should get the aftermarket LSD rather than the SportPKG LSD ??

I'm planing on going to the track to, so is there a big difference !? until now I couldn't find someone talking about the difference in the two differentials

I guess the decision would come down to the going rate of second hand sport differentials when compared to something nice that is better suited to track duty. For the labor involved you might be better off choosing a diff that is an upgrade over OEM.

The sport model LSD is viscous, it is a design that is very durable on the street but becomes less effective (or ineffective) as the diff fluid temperatures rise which make it not very popular on track. It is also going to cost extra in parts thanks to requiring different stub shafts.

A unit like the Quaife is a mechanical torque sensing differential, it is going to direct torque bias to the axle that has the most grip up to the limit of the torque bias ratio. It is a straight swap for the base diff and still has great street manners and in also good on track provided you like to keep all your wheels on the ground :)

The other aftermarket differential option is a clutch type differential (like the Carbonetics). These units have clutches that come together under acceleration (power), and depending on configuration also potentially under deceleration (coast). The amount of lock up is dictated by the number of clutches inside the core. The pro's can rebuild the units to alter the amount of lockup they need for a given car or even a given track. The clutches will also stay locked if you go over a curb bump that gets one wheel airborne (provided you were on the power of course).

Bottom line is the Quaife is the best all around upgrade for the base. For the sport model the Carbonetics is probably your best bet.

I'd agree. Although an option might be to swap the whole pumpkin with a sport owner that wants the base pumpkin to upgrade.
