More english prease?!

The rotor sits perfect and does not hit the ball joint. But is off center to the caliper is what i'm gathering.

Does it sit too much towards the inside of the car or does it sit more towards the outside?

and your previous post said it was 326mm diameter...isn't it 26mm too large for the caliper as well?

the rotor sits perfect, and the brake surface is excellent.

however i would either have to grind up to 5 mm from the caliper bracket area to even have it centered. i cannot even measure how much that rotor has to be resized, however i will post a pic in a couple of hours.

the rotor sits too much towards the outside, if we could find a caliper for this rotor, it woud be awesome....

pics...







but.... to keep caliper centered....

lots of grinding..



even trying to bolt caliper outside.. using a 20 mm spacer..

so just keep it simple, and get the supras, if you are able to find some that can be drilled and someone to do it...

or you want this rotor, you need to find another caliper.



lots of grinding....



that puts the rotor and wheel to far away from the center of rotation, and thats a no no...

Honestly, We could easily have an adaptor bracket made for this. (IE small block of aluminum cut and drilled) So that the caliper sits in the correct place and we have a bolt on rotor.

It looks like the caliper mounting holes are sitting right on top of the knuckle holes. This would be a pretty easy adaptor to fab up.

Then I could get these:

well actually no, because the caliper is not all the way sitting down and grasping the rotor... it still needs to be pushed down at least 10 mm, and still the holes do not align.

i was looking also at a camry spindle, looks alot like our celicas, with the difference of the mounts spaced further, giving chance of a bracket, but then again, too much trouble when u can just drill supra rotors.

Gotcha.
Well like all you other nuts, I picked up a "X" rotor today. We'll see how she fits and i'll report back, it should fit minus a 7mm offset.
Which is an easy $25 spacer and that's it, much easier than drilling.

PS njccmd2002 I saw your thread about brake rotors and the Subaru. I assume this was your research for the STI rotor.

To add information

Subaru rotor? Thats good. Looks like regular impreza. Hmmm that is awesome. Maybe 2 mm shim spacers each side and perfect!!!!!

That's a nice find. Two questions:

You removed the dust shield for the rotors right?

How did you compensate for the difference in height?

I never had dust shields on this setup with the brz rotors.

There is no compensation, put everything on normally.

So an update to this thread would be

Front: ST205 calipers bolted on and WRX front rotors bolted on

Rear: ST205 Calipers shimmed 5mm away from the bracket towards thr rotor and ST205 rotors?

Now we need to find an ST205 rotor replacement since I'm guessing they're gonna get hard to find and more expensive as time goes on.


The only thing I dont like about the setup is that the front brake rotors are smaller than the rears, 20mm smaller, too.

that stuff had been added to the OP already.

St205 rotor replacement for what the rears? If so I have a site from the UK that sells EBC oem replacements. I doubt they will discontinue them for a while.

My personal experience with the larger rear rotors is that the brake bias feels ALOT more even. Braking isnt as nose heavy and the car doesnt dive forward at all during heavy braking, which I find VERY helpful when I race.

That's interesting...

Yeah I was suggesting a replacement for the rears that perhaps we could find local to us.

Ah gotchya. I think the 205 rears are out best bet.
The only downsides of that rotor are the spacing of the caliper and the ebrake shoe only has half contact on the inner drum.

Those arent really terrible downsides in my eyes.

the company in the UK that I have listed in the OP ships super fast with tracking too smile.gif

I will keep my eyes open for any rotors that look like a match to the 205 rears
