Hey I wanna make a request and possibly make this a sticky if it turns out. I want a list of what cars suspention and brake and diffrentials are interchangable with are cars
Iv herd mk4 supra diff and brakes fit. And ls400 brakes I'm unsure about but of herd of it. Thx for all the help! Let's make a interchange list!

 

And thx to carfreak70 we know that sc300 front seats and coilovers fit the 1st gen gs

 

dude i dont mean to be a buthead but every other thread is about this it seems...but there is several threads about this:
https://www.clublexus.com/forums/gs-...nterchangeable

https://www.clublexus.com/forums/gs-...nterchangeable

that is a couple for examples of whats out there in search land.
good luck bro!!
but to quickly answer your question... mk4 brakes fit with little modification.
ls400 brakes fit with modification. the swaps have been covered, check in the diy/how-to.

 

My bad. Guess. Iv never seen a compleate list anywhere even with searching. Nor in the how to.s. someone should sticky one if they haven't been already

 

well im not saying dont do it, because there is no complete list, i mean you could compile all threads that talk about interchangeable parts, ie: suspension, seats, ect. but it kinda seems like it would be a alot of work for not much payoff. but anyway i know from my own wrenching that these parts work (or dont):
2gs upper control arms
mk4 supra brake upgrade is bolt on with some trimming of brake shield(check the diy/how-to)
ls400 brakes fits with some grinding of the tie rod bolt and trimming like the mk4 brake upgrade.
sc seats work
most (mabey all) toyota/lexus steering wheels fit and can be retrofited for newer style air bag plugs.
sc steering column doesnt fit
sc brake calipers and rotors fit (although its a downgrade)
i guess if anyones knows of anything else they can add, but seems like recently people try to start a "interchangeable part" or "part compatibility" thread and it ends up dying after a few posts.

 

I will compile a full list out of the other ones. Just gonna take a few days. When I get to a actual computer I don't wanna even try that on my android
