So as for control arms the only ones that are different are the rear lowers? Aside from bushing material.

yes, provided you do the uneven suspension mod, add 1/4" spacers up front to get enough room to have full suspension travel (at least with eibachs).

Can someone please confirm this for me? My 98 SC400 has several loaner suspension parts on it from my 1998 Supra T.T. 6 speed. I installed the front and rear Supra T.T. sway bars and and upgraded the rear sub frame mounts on my 98 SC years ago. I just finished replacing both the front and rear Upper Control arms and the front Lower control arms as well as the front sway bar end links all donated from my Supra. So if I already have the rear Supra T.T. sub frame mounts and sway bar, does that mean I can go ahead and replace the rear lower control arms and rear sway bar end links with one's from my Supra? All I know is that the rear sway bar end links were absolutely not compatible with my current SC lower control arms. I assume once I change the LCA to Supra than the Supra sway bar end links will fit. I also installed both front and rear Supra struts and springs at the same time. I'm also waiting on my front supra calipers to be powder coated black and have yet to verify if the front Lexus SC400 brake caliper mount bracket is compatible with my Supra caliper? I assume it is because I haven't seen it was or was not anywhere that I have searched so far. Thanks in advance.

I'm a nube here and hope the OP or informed folks will see this and respond.

What is the benefit of swapping to Supra rear end?

Cheaper parts?

better performance?

Reliability?

Ride smoother/harsher?

other?

I have an opportunity to grab a Supra rear assembly and will consider it if Supra replacement parts are cheaper. I'm already tired of Lexus parts prices.

This is a great thread. Does anyone know if the front subframe is compatible between the two chassis?

Should be interchangeable.

Supra Dr says he's running a supra front subframe on his SC in this thread:
