MY13GS350

Does the 2013 GS350 (RWD) have a limited slip differential of some kind?

i.e. will both rear tires spin if traction control is turned off?

If not... what are the after market options?

The reason I ask is because there is no mention of it in any of the sales material from Lexus (and my salesman didn't know) but when you look at the IS-F it specifically states "Rear-wheel drive with TORSEN® torque-sensing limited-slip rear differential"

Thanks for any input.

It does not have a mehcanical LSD. IS F and LFA are the only cars in the Lexus line up with standard limited slip differentials.

So to answer your question, no. There are no aftermarket options yet but there maybe some in the future but most likely in the Japanese market.

wow, disappointment there. I wonder if the ISF parts will work.

You also forgot about the IS 350 fsport they too have a lsd also the new LS it too got a lsd

wonder if these will work.

Anyone know if it's possible to put any of the LSDs from the ISF. IS FSport, or LS on our GS?

So the IS and LS FSports have LSD but not the GS? Not even the GS FSport?

I found this page, and they say the car comes with a limited slip, but I'm guessing this is for the AWD?

The standard Vehicle Dynamics Integrated Management (VDIM) anticipates loss of vehicle control and governs all of the vehicle’s dynamic handling systems – the Anti-lock Braking System, Brake Assist (BA), Vehicle Stability Control (VSC) and Traction Control (TRAC) -with the electronic throttle control system. VDIM employs these systems collectively and seamlessly to help make corrections while allowing higher dynamic capability. The system also provides a limited slip differential effect.

ItzFilyO

Nice. Since VDIM is standard on all GS, so that means mine has it too.

Christobol

I dunno, it says limited slip differential effect

As long as it doesn't let one wheel spins freely then it's good enough for me.

It looks like that system will apply brake to the spinning wheel and transfers the torque to the other wheel to get the car moving.

That's true. And while it's ok for street driving, it's horrible for track driving as it will destroy the rear brakes. Having driving my 2013 GS F Sport at two different tracks I can certainly attest to that.

Lexus hasn't yet managed a real track-worthy car (LFA aside and IS F partially aside) but they're getting better. Hopefully the RC F can at least hang with Cadillac's CTS V Sport. On that note, maybe some day, Lexus will even make a CTS V competitor.

Christobol

Well the IS300 was great at autocross in the stock class. I did a good job of dominating the class so long as the top speed was limited. And I was able to beat a Ferrari F350 around the track twice if you excluded the straightway where I only hit 115 but he said he was going over 165. Granted the guy was an awful driver on an open track.

I want to take my GS out on a track a few times to get a better feel for how it handles. Though I really want a LSD first. Though if the onboard systems over road the mechanical by intervening before the gears hit their limit then it wouldn't be much use.

So when you say it has destroy the rear brakes, you simply mean you need to replace the pads, or something worse?

ItzFilyO

Yup, the only bad thing is it wears your brakes faster this way. Most likely the pads will go first, then the rotors.

The ISF is supposed to be the direct competitor to the CTS-V, C63 AMG, and M3.

The F-Sport models supposed to compete with the V-Sport, M-Sport cars, and whatever XX-Sport other manufacturers are coming out with, but Lexus use the same engine as the regular model instead.

Nismo

Yes, that's right.
