If this has been covered already I apologize.

I am aware that the RC-F has a Torsen mechanical LSD with two active electric motors alongside the rear differential casing (very trick) but I can't find any concrete information about the non-F model.

Do the RC350 or F-Sport versions have a standard or optional LSD? If not, is this something available though the TRD, OS Giken or Quaife catalogs sharing a common case design? It would seem an oversight not to list this as an option.

I'm not certain about the base RC350 but I did read that for the international version of the RC350 F-Sport, it will have both a Torsen LSD and rear-wheel steering. It might be a bit different for the US market though.

From the recent video reviews of the RC350 F-Sport, there is mention of the rear wheel steering feature but I didn't catch any reference to a Torsen LSD.

I know the official US Lexus brochure for the RC-F has been released with all the options available for the car but I'm not sure if the RC350 brochure is still unreleased or not. When it becomes available, we'll know for certain then.

EDIT: Speaking of the release of the RC350 brochure, it looks like the detailed specs have finally been released on the Lexus website: http://www.lexus.com/models/RC

Unfortunately, I see no mention of the Torsen LSD anywhere on the website or the brochure: http://www.lexus.com/documents/broch...C-Brochure.pdf

Thanks for the heads up!

That's what I was afraid of: the option and R&D is there but not for U.S. customers. Still, if it's available in some market and has a part number it can be obtained and installed at the dealer. The online spec sheets were only for the U.S., correct?

I thought Europe wasn't getting the RC350 though.

Here's what I found using the pre-order brochure which specifies a LSD option for the "F-Sport Plus" version of the RC350:



I went on the Lexus International web site and I was unable to find any information on the F-Sport Plus model so it's either not being offered in the US or it might have been removed as an option for all markets...

What this tells me is that Lexus definitely has the R&D and preliminary marketing completed for an LSD package on the RC350 F-Sport but may or may not be offering it Stateside (or possibly anywhere).

It may be that first year models don't have all the option packages ready yet from suppliers. It's only just being released now anyway. We'll see. Thanks guys.

Probably won't have it...none of the Third Gen IS's do....buy an RC-F.

Wanting a limited slip differential shouldn't be the only reason to jump to an RC-F.
