The GT-Four Brake Upgrade, ST205 Brake Upgrade for 5x100 & 5x114 PCB Options

[playr158]

Can a mod sticky this thread alreaddy?!

[Tigawoods]

yeah! sticky!

still looking at rotor options since thats the main concern I believe

this is the centric rotor specs for a 2005 Subaru Impreza
specs are basically the same as the brz, but this one is a few lbs. lighter



I am searching around for big brake upgrade rotors for the wrx and brz.

Stoptech (centric) has a BBk for the WRX but the rotors are too large (328mmx28mm)

well actually it seems like alot of the BBK kits for the wrx and brz are 328mm.

Id also like to merge a bit of the info from the 5x114 conversion into this thread so that it can show some info for people that would like to switch hubs when converting, Ill also have to add the possible rotors for that too. Rico will be a good source of info for that.

AP racing has a 2 piece rotor with pretty good dimensions but the thickness may be 1mm too much



also here is a list of cars with a 5x100 bolt pattern. maybe we can find another option out of the list (for some reason out cars were omitted from this list, i grabbed it from vwvortex) The best possible options will probably come from turbocharged compacts. Non-turbod compacts dont seem to have much over 270mm

Added to the stickies.

[njccmd2002]

with a 5x14 hub change, just use oem supra rotors...

[Syaoran]

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

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

Yeah you guys have it great. In my case, it's 320 just for shipping, which is 4x as much as shipping anywhere in the US.

This is stupid XD

[Tigawoods]

ship it to me on the east coast and then Ill ship it to you! It would probably be a heck of alot cheaper

with a 5x14 hub change, just use oem supra rotors...

BOOM.



Ill have to ask rico what he did for the rears again for his hub change

[playr158]

5x114 swap only works if you don't have AWD
I need to find 5x114 hubs / rotors that will work for AWD

oh and still no 2-piece for the supra rotors

I'll keep that in mind. Thanks.

Well, if you think about it, if it's already AWD it already has GT-Four brakes which would make this thread pointless for whoever's doing it.

BUT doing the 5x114.3 hub swap might just be a redrill deal..

[playr158]

Unless you have my car or a few others here who have/are doing AWD swaps and keeping McPherson suspension..

But then what I said wouldn't apply, because it's not "already AWD". lol

Man oh man do I have a lot of information to add!

Rotor Options:

FRONT:

93-99 Toyota Supra NON-Turbo




REAR options:

93-99 Toyota Supra NON-Turbo



*Height too large at 67.35mm?
*Stock GT4 is 59, GT is 65

2003-2012 Infiniti fx35



* Hub size 6mm too big, bolt size 12.7, should be 14.5

2010-2013 Lexus RX350



*Nom Thick, should be 16 (6mm too small)


BEST OPTION (IMO), and what I will be running:

2002-2010 Lexus SC430/ 01-05 Lexus is300/ 95-05 gs300 / 98-00 gs400 / 01-05 GS430



*Nom thick, should be 16mm, 4mm off - Do not see this as an issue

*Hat height of 63.3 should allow for proper contact of GT E-Brake shoes. Stock GT4 hat height is 59 (reported issues of only 1/2 of E-Brake making contact) and standard GT hat height is 65.

Wouldn't the mkiv supra hub work in the rear for the awd knuckle on the celica?..

[Tigawoods]

thanks rico!
Ill add that stuff tomorrow.

You've fit the rears on already right?
The smaller diameters of those options you listed compared to the 315mm GT4 rotors seems like it could be an issue. 6-9mm seems to be the range of difference from what you've listed. It isnt MUCH but its something.

[playr158]

Wouldn't the mkiv supra hub work in the rear for the awd knuckle on the celica?..

Honestly I don't know. It comes down to shape/splines/thickness and there aren't diagram/measurements on the internet like there are for rotors.
That and usually only the Dealer sells them and for not cheap.

2002-2010 Lexus SC430/ 01-05 Lexus is300/ 95-05 gs300 / 98-00 gs400 / 01-05 GS430

This looks like a pretty good option for rear rotors and a 5x114 GT4 rear brake conversion

[Tigawoods]

2002-2010 Lexus SC430/ 01-05 Lexus is300/ 95-05 gs300 / 98-00 gs400 / 01-05 GS430

This looks like a pretty good option for rear rotors and a 5x114 GT4 rear brake conversion

the 8mm difference from the ST205 315mm concerns me.
What do you think?

My setup with the 315mm ST205 rotors has the pads right at the edge of the rotor


the rotors are thinner than the ST205's because the 205rears are vented. just a remark.

[njccmd2002]

Mr2 rear hubs is another option... For awd

[playr158]

^some how I completely missed the concept of an MR2 rear hub

[Tigawoods]

just thinking about this the other day and how that these smaller diameter rotors will change the braking bias of the car. I cant say for certain to what extent though. My F:300 and R:315 is a great balance. Its possible that a few MM's off the front might not make too much of a difference. Just thinking out loud

continue with your day.

[Fastbird]

I'll be ordering Rav4 Hubs, bearings, poopra rotors shortly for mine. Even though I'm selling. I have these big calipers and have been meaning to do this for a LONG time. Props to Tigawoods for the good info. I only last year discovered the Rav4 hub swap which totally changed the game for this. Fortunately, my Tenzo R DC5 wheels are a dual 5 x 100 and 5 x 114.3 bolt pattern.
