2020 IS350 F Sport LSD in 2nd Gen IS350
I noticed that the 2020 IS350 F Sport has a limited slip differential from the factory. I know the 3.13 FD ratio from the 2020 IS350 would not be ideal with the 2nd Gen IS350 transmission gear ratios.
However, does anybody know if the 2nd Gen IS350 (4.08:1 FD ratio) FD ring gear will fit on the LSD from the 2020 IS350 F Sport? Ideally in the 2nd Gen IS350 differential carrier.

Bumping this because I am really curious.
https://www.clublexus.com/forums/is-...l#post11314231 LexSense got this far but never made another update. If the pumpkins are the same between 2IS/3IS, there's chance the ring/pinion are the same size. The other question is whether the ECU can be modified to accurately reflect speed so as not to completely torch the transmission's logic and odo. If you're on a 2nd gen i'm guessing RR or whoever has cracked that ECU wide open, but I might be out of luck on my 2020.
