Looking to upgrade my rear brakes... I have heard the cheapest way to do this was to install LS brakes... I am planning on getting the Supra TT brakes for the front...

What I want to know is which brakes are a direct bolt up for the rear of the 98 GS400? Part numbers would be great if you have them for everything... pads, shims, calipers, ss lines and what ever I am missing...

Thanks

They shouldn't. GS's rear brakes are already 4 pistons anyways (very small compared to the Supra's rear, but still 4 nontheless).

i don't think any of them do. otherwise you would have seen them by now

no...... gs rear is 2 pistons.... one on each side of the caliper. even the supra rear is 2 pot rear, i am pretty sure.

there is no way they will put a 4 pot rear when the front stock brakes are only 2 pots

Whoa, I was high, haha. Yea that's what I meant.

That would be the only complaint about my TT bbk is the fact that the front end really dives......it does stop really well, but with my sti it didn't seem to nosedive near as much. more of a sit down feel! But I highly recommend the TT fronts!

You need stiffer suspension. It's the cure for the nosedive.

keep in mind that not all 2 piston rears are created the same. brake balance will slightly be off with TT/ls4 4-pot up front with stock 2-pot but i don't think you'll mind.

So am I wrong about any of the LS brakes for the rear bolting up to the GS? I thought I read some where here that someone had done that .... I couldn't find it by searchingh though.. From what I remember... the poor man's bbk was to get Supra TT brakes for the front and then to get LS rear brakes for the rear because the LS rears are bigger than the GS rears..... Any help on this guys?

thanks

I have no idea just a guess could they have been just talking about the rotor size is bigger and just plop that on the rear?

supra tt bbk = ls400 bbk

except supra calipers are heavier. also, none of the rear ones bolt up to 2gs. if you want it to bolt up, you need to fab your own parts.

I believe the Supra rotors are bigger too. The LS brakes need an RCA kit = BOOO...

Also the Supra TT brakes were the best factory brakes since it came out in 1993 and were the best until the Porsche (forgot which model) stock brakes beat it in 2006 I think. Not too shabby.

The LS rear brakes aren't worth the effort.

The 2GS rear brakes are already fairly large,
and by messing around with different front
& rear brake systems all you do is upset the balance.

For example, the StopTech BBK is designed to be
balanced with the OE rear brakes. They increase
brake torque, not just clamping force.

If you want to change the brake bias, you can
accomplish this by using a more aggressive pad
on the stock rear brakes. I did this on my MR2
to change the bias slightly and it worked great.
Of course, the MR2 chassis has some rear weight bias,
(45% front/55% rear) so this is helpful.

On a sled like the GS the front brakes do about
85% of the work anyway.
