Upgrading to a limited slip differential

[Dia1Up]

Interesting...hadn't seen that. But can they get any Eibach parts, or only that one combo? And how much is installation at your dealer?

I will check with mine about this and the LSD (Limited Slip Differential), but the last time I asked about LSD (Limited Slip Differential), they had no clue whether it would seamlessly retrofit to a 2018. I also only want the rear bar, at least to start.

Looks like just Sway Bars and Springs for the Stinger from what I can tell.
I can try and get a quote if they have time today. We have full service staff on, but its the day after a long weekend here. They are swamped. But bare in mind, honestly what ever number I tell you will pretty much be irrelevant heh. Every garage will charge different rates and different amounts of time. A better option would be getting you a rough time estimate.

Your dealer CAN find out. It's just if they want to or not. They have to match the parts up, so its a pretty huge amount of manual research on their part. Especially if there's no official internal documents covering such things. I might be able to convince mine to do so? It's a hard sell for me to ask them to take a few hours for me and our forum buddies to make 0 sales on heh. (We only have about 3 Stingers in our greater region heh)
If I remember the 2018 Stingers had LSD option in the RWD anyways. A good business tries to reduce costs as much as possible, meaning as few different parts as possible. There's a good chance the RWD and AWD rear end is the same, and hasn't changed from 2018 on. Just my guess. I'm DEFINITELY not a mechanic. Whether the LSD and the non-LSD rear end is the same is a bit different. That I'm not sure. When I asked my service they aren't sure either. It's possible, as the normal GT doesn't have one and the GT Limited does. But how much work and what other parts (if any) is a different story.

Off topic, but @Kia Stinger can you PLEASE disable this feature? It makes a mess out of posts all the time. We know what an L-S-D is.

One way to know if you have it is to look at the full plug.

That makes me wonder if the casing is different then. If they have the OIL lettering in the cast into it.

Any update to this? Went for a drive after the +20 cm of snow in town recently and would really like to have an LSD. I don't mind buying the whole pumpkin if it drops right in, I'd just like to know if it does before I buy it. My beater Legacy GT has more traction than the Stinger in my skating rink of a neighbourhood

What tires are you running? I was out after the snowfall as well, and Edmonton can not plow the roads worth a damn, but I didn't have any issues at all. Toyo Observes, mind you I do have the LSD as well.

First time in snow with the Stinger so I went out to an industrial area for a little bit of hooning, wanted to see how it handled mostly and I am extremely impressed with it.

Your Legacy will have great traction on ice or compacted snow versus the Stinger even with the LSD. Subaru's AWD system is superior to almost every other manufacturer.

That written, you should be just fine in the Stinger with winter tires on.

@Hockster I'm running Pirelli Sottos and they're decent, but I'll be switching them out for studded Hakkas next time. Edmonton road cleaning being what it is I want as much grip as I can get. Too many skating rinks leading up to intersections and I slid through one going <5km/hr in Lake Louise a few weekends ago.

I'm tempted to swing by a dealership and take a 2020 for a spin to see just how noticeable the LSD is. Even if it's halfway between the grip the Legacy has and where my Stinger is at, it'd be worth it to me to install the LSD.

@bpang1 I know all about Subarus and their awd (at one point there were 3 red Legacies in my driveway lol), but the Legacy is an 03 with just a viscous center diff and torsen LSD in the rear, no traction control at all. It shouldn't be that hard for a car 15 years newer to be able to at least be comparable to that. I want to know if it's possible to add the LSD to my Stinger to try and get it on the same level as the Legacy, which is why I posted in this thread. Would you tell someone looking into a JB4 or Racechip "you should be just fine in the Stinger with stock power level"?

I know tone is damn near impossible to convey through text, so I just want to say I'm really not trying to be rude here and I think you mean well, but I just don't think that comment in a thread where people want to know if they can install an LSD is super helpful.

 

[Hockster]

Tork has the LSD listed on their site. There's been a couple people asking about the swap, not seen anyone that's actually done it. MIght be best to give Tork a call and see if they have any more info. Don't sure if there's any 20's left on city lots, but trying a 21 with the PS4's would be silly.


Edit: love how the forum adds stuff into the posts. We all know that LSD isn't the drug here.

This is 100% untrue. The KIA AWD system is at least the equal to anything available on a Subaru today. It is a copy of the Nissan ATTESA system, which if you care about performance on dry pavement as well as snow, is actually superior to the Subie. And I have owned multiple iterations of both over several generations (in addition to Audi quattros and Volvo AWDs and including a 2018 and 2021 Subaru), so am not just spouting theory.

I don't agree...There are many AWD variations, even within subaru and audi models for example so you can't generalize by brand.

I'm pleased with the stinger's AWD in general...glad it's full-time AWD which is great for handling, stability and safety IMO though may siphon off 1-2MPG where other companies disengage AWD under normal conditions. A reasonable tradeoff for me. The best feature IMO is the variable center differential to offer more RWD feel. I'm really impressed Kia included this feature where other manufacturers have not. You need to go with a subaru STI OR a much more expensive european car to get a similar feature (or the unique and expensive nissan GTR)

Subaru AWD is notable as the only symmetric system which has some advantage to AWD geeks - it's the most balanced/predictable when you get the car sideways (only a fraction of drivers seek out this experience). Subaru's better versions have 3 LSDs (front, mid and rear....avail on STI) which is what you want on loose terrain, snow, etc. Basically a rally car setup.

For tarmac you don't really need all that and instead you probably want want the super fancy rear differentials of audi and others that can send power to just one of the wheels to rotate around corners better. Kia doesn't have that, btw. Our stinger's have a small driveshaft that goes from the transfer case to the front differential just like audis (and nissan as you mentioned) that have a longitudinally mounted engine. It isn't bad, but not inherently balanced...similar design as pickup trucks though...

I've been driving AWD since audi's magnificent coupe quattro turbo from the early 80s. - look it up if you aren't familiar. I love driving in the snow and enjoyed awd volvos too - they use a haldex system as do the remainder of audi quattros. These are all good systems that will get you through typical snow situations, but some are better than others depending on what you're looking to do...

I would love the option for a rear LSD on my AWD GT2.

My previous car was a 2011 STI hatchback. There is no comparison at all between the stinger and the STI. The STI's AWD was superior in every way.

I've already been through one winter in the stinger. It is just ok, but not fantastic like the STI was. You can feel the stinger wallowing and shifting around as it detects slip after it has happened, then reacts. This simply does not happen with a mechanical LSD. I'd love to have the sure footedness of my STI again.

You do have the option...that's the whole point of this thread.

 

[General_Vodka]

I am pretty sure it will fit if the driveshaft with the awd ends up in the same place as the RWD. still it's not going to be an easy bolt on mod lol.

Reviving an old thread, I dropped an email to tork and we'll see what they say about what I'd need to do to do the upgrade on the 2018 gt1 I just bought.

Sounds good..

I am possibly getting a new job near them...if so, I am going to get their tune and also inquire about this as well.

Thank you as they've been completely unresponsive to me

 

[Roy Martinez]

I sent them a message on their website months ago and never heard back.

I'm still under the check with the dealer camp. I'd imagine the rear end on both the AWD and RWD are identical. I mean in Canada here we have 2 trims of stinger, the lower end one doesn't have an LSD, the Higher end does. I don't see why it isn't possible to plunk the factory one in
