Upgrading to a limited slip differential

[Marc Collins]

Thanks...this is very informative to help understand what the LSD will and will not do.

This is a good question...I don't think the other couple guys who did their own swaps needed to make changes, and I would expect Tork to mention it. But I have felt the car pull power accelerating out of a turn (moderately, in the wet) when I would've expected the transfer case clutch pack to lock up and send power to the fronts first.

I was in Smart (probably Smart Eco) at the time, which likely allows the least slippage and most aggressive intervention, so Comfort / Smart Comfort is probably less eager and Sport definitely less eager to cut power. One would hope that the LSD would react first, then AWD (lock clutches), and only cut power as a last resort, but that may only be the case in Sport. A before/after comparison at various speeds in different drive modes would be illuminating.


I remember some questions as to whether pulling the fuse would eliminate normal fluid circulation within the transfer case and cause long term issues due to heat buildup. @Savvas it's been a few years since you posted this, do you have any observations after leaving the fuse out and (it sounds like) driving fairly aggressively? Have you put the fuse back in and been able to tell whether your AWD still kicks in as expected?

My Canadian 2019 awd has an open rear diff. The AWD fuse just disables the front wheels from getting any power. It is my understanding that all AWD stingers after 2019 have a rear E-LSD. GT2 non AWD models have a mechanical LSD. Adding a mechanical LSD to an open diff stinger might need torque vectoring disabled.

I put my AWD fuse back on and remove my JB4 during winter/snow driving and I have not had any error (fingers crossed) @ 160k km

None of the Stinger/G70 have e-LSD. Nor do any of them have true torque-vectoring, just ABS-based safety nannies.

I can tell you a very basic experience with my RWD 2.0 GT Line. It came with an open diff because I live in the temperate zone. All 2.0 GT Line Stingers in Europe sold in the frigid zone came with an LSD as standard. Sadly, for us in the south the LSD was not even an option.

So, I bought an LSD from a 12k miles wrecked Stinger and installed it on mine.
I can't say too much about what happens at the limit because I've not tracked it. And, with the 255 rears my 2.0 doesn't really break traction that easily.

But I can give you my experience on snow and ice. The TC steps in much later on snow, or not at all.
On ice it's even more noticeable. With the open diff I once almost got stuck trying to go over the smallest of curbs because one of my rear wheels was on a patch of ice. The "torque vectoring" couldn't move enough torque to the other wheel. With the LSD I have tried multiple times to accelerate with one wheel on ice and the car just goes with ease. No TC, just smooth acceleration.

I'm happy with my upgrade for driving in winter. It has given me much more confidence in the car.

Thanks for the useful report.

I stand corrected. No eLSD and brake based torque vectoring only.
