Thanks Lobux....So does that mean that should someone come across a front-end totaled 2011 ISF they should be able to make a direct swap of the diff and rear subframe into an 08-10 F?

Only what's documented in the service manual. I don't have a friend in Lexus parts who would be willing to identify all the changed pieces from '10 to '11. If I did, I'd probably just buy them, but since I'd like the Torsen too, buying the whole rear subframe and bolting it in sounds a lot more appealing.

Lexus has since tweaked all suspension elements. Spring rates are down in the front and up in the rear, and there are larger anti-roll bars, stiffer subframe bushings, and longer bump stops, which effectively increase spring rates when the car is nearing its maximum roll angle. Lexus also lightened the front hubs and control arms and slapped a Torsen limited-slip differential in the rear axle.

I don't trust magazine articles to get this stuff right. I've seen it screwed up too many times. I'll believe it when I go to Lexus and see different part numbers.
If I believed the magazines, I'd still think the Supra TT had a small and a large turbo in the stock twins setup, and the purely cosmetic wing makes 90 lbs of downforce at 80 mph.
C&D screws up the details more than I'd even care to mention.

No doubt. I already thought of trying to bolt the whole unit in, but it's clearly a no go. Very different sizing. I'd be happy with just being able to swap the spool, but there's not enough information in the service manuals to determine this before pulling a couple of them apart.
