any news on this Dustin? I'd love to see this figured out

i mean didnt culp do this a while back? ask him

I know its been done, I'm more interested to know if Dustin got them finished and put on his car.

I agree with Culp. I'm starting to think the ST and GT knuckles are in fact slightly different. Luckily, I'm fabbing up brackets for my ls430 calipers all the way around on the celi.

updates?

We just bought a house with a 2.5 car garage and we're moving in less than 4 weeks, everything's been on hold until then.
I'll be doing the rears also with the fronts.

sweet! let us know.

nothing beats having an awesome garage,,

I drilled and tapped the hubs m14-1.5, got 25mm stainless bolts, had the rotors trimmed to 300mm, and over a year later I finally got around to installing them.



more to come in a few days.

*crossleggedwaitingonthefloor*

very nice!

let's see the

did u use any spacers or brackets

ok to recap

I bought a set of calipers and rotors.
I bought new pads and the fit kit from toyota (supra pads/kit).
I shaved off a few mm from the mounting points on the calipers so they would be centered with the gt-four rotors.
Painted the calipers up nice and shiny.
I finally had the rotors trimmed to 300mm.

installing
Removed the old brakes and drilled out the holes on the hubs from the stock calipers.
The stock calipers bolt on the rotor (outer) side of the hub. The GT-Four calipers bolt onto the engine (inner) side of the hubs.
I used a M14-1.5 tap and bought stainless steel bolts (so they won't rust) to match (M14-1.5 x 25mm). The tap and bolts I used are a little big, I could of went with smaller ones but didn't.
I drilled out the hub holes to accept the bigger bolts and tapped them.
I widened the holes on the calipers so the new bolt would slide through.
The bolts now go through the calipers and thread into the hubs, as opposed to the stock calipers going through the hub and threading into the calipers.
Bolted them on, bled the lines, now I have GT-Four brakes up front.

some notes, I have ss braided lines but they looked a bit short, I'll probably pick up new longer ones soon, JIC.
My wheels don't have a great offset so I installed 10mm spacers (front and rear) for clearance up front.
They wouldn't have fit without them with my wheels.
For giggles I tried one of Stef's wheels (enkei rs5s IIRC) and they didn't need any spacers, they have a great offset, they cleared the calipers just fine.

I'm just waiting for my bumper to get back from paint then I can actually drive my car again.





I also used some touch up paint (same as my car color) and painted the "celica" logo.

Very nice Dustin!

Hey man wonderin if i could borrow or buy the snap ring tool i lost mine lol u know the one to place the snapring on the pistons

And welcome to the four piston world lol i love mines

I've done this conversion on my JDM SS-I and it is such a pain in the ass! The increased braking power is great but the grief to get the front and rear brakes fitted...

Rear GT4 discs/calipers fitted.





Fronts fitted - how little clearance between caliper and wheel??





I (like everyone else, it seems) had to machine the discs down to 300mm. But they're still catching the lower balljoint, sadly.

you have a how to GT4 rear brakes?
what size are the rotors?

regards

Hey, so here's a question. Is it possible to use GT rotors with 2mm spacers on each sides of the pads? Or is there another fitment issue?
