2012IS250 which mountain drive do you drive on?
I think it is haha. if you have a shop do it, you're looking at spending about 900-1k at least if you purchase a new differential and have a shop do it, but it's worth what you get out of driving with it. I drive on highway 9 and 35/skyline boulevard, right next to the Santa Cruz mountains. I want to bring my IS down to SoCal and try GMR though haha.

If you AWD guys want to get a little crazy, I suspect the rear Torsen diff from an RX 300 could possibly fit in the front diff. The rear open differential carrier on RX300/330/350 is the same part number as the front carrier on many of the Lexus IS cars. Believe it or not, the RX 300 was available with Torsen out back. There are many "ifs" here, including carrier bearings and CV stub shaft compatibility.

That torsen uses larger axle stubs than the open diff, so you'd probably need some custom/magic axles or something to make that work.

Just looked it up, the fiche lists the same stub axle part number for both open and LSD on the RX300. This does seem a bit weird... would you happen to have any further info?

No it doesn't.

41309-20020 - 99-00 Non-LSD Stub
41309-20030 - 99-00 LSD Stub
41309-32020 - 01+ Non-LSD Stub

LSD wasn't offered on the RX300 after 2000.

Yes, you are correct, just found that mistake on my part... that's why I thought it was weird. Thanks for clarifying.
