It has been discussed both here and in the 4th gen forum as both take the same rear bar, but nobody appears to have installed one at this time. There is a thread on the 4th gen forum where someone said they plan to order one.

No experience with Lexus but changed to a beefier sway bar on a Volvo and a noticeable/improved difference holding curves. If there's a better sway bar available I'd opt for giving it a try. Following for your feedback.

but I confirmed prior to ordering that it would work with AWD, they said yes.

This ^^^^ Corner exit greatly improved as well as corner entry push reduced. Good time to replaced the end-links.
