Is it possible to fit the upgraded brakes from a 93-up LS400 within the 15" wheels of a 90-92 LS400? Does the 93-up LS400 share brakes with other cars (GS, Supra/TT, etc.)?

Thanks,

You would have to change to the 16" wheels.

Supra TT brakes require 17" wheels.

Most of the parts are interchangeable on that family of vehicles.

Hey Todd,

Will it just go right on a 93 LS400 without any modifications?
How much for a Supra brake kit?
Steel lines, rotors, calibers, etc.?

I'm curious about this as well. This is the first I've heard about Supra brakes for the LS. I thought it was reserved for the GS and SC. Someone please inform us!!!

My 96 has 12.4" rotors with 4 piston calipers. I imagine you would need at least 16" wheels to clear them. Ask this question on the SC forum as many have done the Supra upgrade and I was told it was very reasonable at around $800.

So John should I do the Supra upgrade or get a RMM upgrade?

JBrady

Lou, I am not sure of the details of the RMM upgrade. Don't they have several levels up to and including super-trick looking (super expensive) stuff? For a show car the aluminum center section with bolt on rotors looks best (formula 1 looking) but very expensive. If set up correctly (important consideration) these brakes should allow racing type performance and repetitive fad free operation from VERY high speeds. That said our cars have pretty decent brakes stock. The Supra stuff may not be bettery than my 96 stock stuff, heck may be the same! The HUGE benefit to factory stuff is availability of service parts. If you need pads, rotors, bearings, calipers, etc, etc it is all available in from any dealer. If you go exotic stuff your car could be sitting for days and even weeks waiting for a replacement part...
