I've got a total lost 97 LS400 at my shop. I'm plannng to take out the front brakes with 4-piston calipers for my 93 LS400. Is this a possible swap? How am I going to do this, install with the whole knuckle?

That would be my thought...install the knuckle/spindle if it will fit the later A-arms.

Hey Lonely , Call dealer and find out what parts are the same for 1st to 2nd and start there... .............When working on persian451's car I tried to put some 2nd gen rotors on to see the difference so I have a good idea what has to be done..............And also your wheels may not clear do to offset.......If you want some help PM me ........................MIKE

cant you just swap the rotors and calipers?

Lexkost

NO, more to it than that........

im going to try this setup on a sc300 on the weekend

persian451

didnt we need to chagne the spindle as well to make the application work?

ATSOU

I think the spindle swap is easy, I'll just remove the knuckle with rotor & caliper and swap it on........I'm affraid that there are some custom brackets needed to fit this project

persian451

well, we can't say it doesnt work unless someone tries it first

This may be pretty involed as I've thought about it more.
Certainly nothing a plasma cutter and some welding cannot overcome. For the average guy though, this become complex.

Wheel off-set,
hub
Let alone the brackets to accomodate the caliper for the larger disc.

I wonder if the whole A-arm asembly may bolt up...then it is a whole swap so long as it does not throw the front track off.

As persian said, gotta try it.

just posting my results, i was able to swap the front ls400 rotors and calipers to the sc.

how many piston do the 95+ ls rear calipers have?

Hey Eric,

I've got a better idea....do a Supra TT big brake swap instead.

great idea, it costs two to three times more.

Shouldn't be a problem for him.
