are you removing you dust covers as a 275mm disc will not fit under them (ive tryed )

Wasn't planning to but I guess I will be now . Wonder if I can use the SS dust covers....

Sweet! Thanks mate. Gotta come and see you about the A/C sometime so if we can kill two birds with one stone it would work out well. I'd reward you for your time and help of course

how you looked at up grading your brake booster before the brakes ?

I read that the 4A-FE and 4A-GE brake boosters were the same, but by looking at them the 4A-GE version definitely looks beefier. Might do it at the same time as the twinpot swap if it's easy enough

maybe ask Jamie if the gt one we fitted to his has made a difference
i think its bigger to keep the pressure stable with bigger brakes

Ohh yep, I noticed the 4A-GE ones have a lot more vacuum lines too (the metal line going along the firewall to the intake side). Wouldn't mind having that set-up as my Blacktop has a couple of the vacuum ports blocked off right now as the 5A-FE brake booster didn't utilize them.

the metal line is a one way valve to keep the pressure equal and constant as it takes vacuum from 2 of the throttles

Good to know. Thanks . Might just grab one off a Silvertop.

picked up the following today

st202 calipers and carriers today
E12 Corolla Tsport 275mm Discs

- Got pads but they were they wrong ones

going to try to test fit them to the levin hub i have and see how they sit in the morning.. will keep you guys updated

ooo nice one buddy st202 celica by any chance :p

so by the end of the weekend you will both have twin pots fitted

Na mine will probably take longer than that, lol. Got a whole bunch of parts to install so have to prioritize a bit. Still have to order my 275mm rotors . Hoping to get the FGK header fitted first.

get you disc's and will make a day of it ill get jamie down to give a hand (sorry about the pun jamie )

As far as I know 2004 D4D corolla discs are a near perfect fit.

A guy in Ireland is running st202 carriers and brakes on the corolla hub with this setup.

I just looked up the specs online and they're the same as the AE101 SuperStrut discs specs, so the carrier bracket would still have to be ground down by a couple of mm's I'd say.

the d4d discs are the 255mm ones (same as stock discs) scott, the t-sport ones are the 275mm ones (same as the levin ones)

Ohhh. I was reading on some sites that they're 275mm but also 25mm, so we'd be in the same boat, lol.

lol yeah.. iv done the research here on my side for these discs as they are easily sourceable

Can someone confirm this for me before I start ordering parts:

I am looking to put twin pots onto my mcpherson hub ae100 Corolla.

If I use the ST202 calipers and carriers I can use a 275mm disc?

If I use the ae101/111 calipers and carriers I can use a 255mm disc?

Right or wrong?

Here's is what a guy in Ireland is using on his ee111 Corolla Beams Time Attack car.

Celica twin pots,


Disk is from a 1.4 , d4d 2004 corolla . Vented 255mm x 25mm thick .

Yes ST202 carriers (3sge model)with 275mm disc
Yes AE101/111 carriers No 255mm disc, they need to be 260mm although some will argue this, I have seen enough of this set up now with my own eyes 260mm will give you the clearance needed over the pads.
iirc the cailpers are the same

the st202 carriers need modding to fit, the bracket needs to be grinded down to make it fit.

you can use 275mm discs with this setup

the ae111 levin carriers need the bracket modding to fit also, but not as hard as the st202 carriers

you can use 255mm discs with this setup (im using stock 1993 corolla discs)

I would still use 260mm on the ss carrier, but thats just me

I did the 275mm rotor conversion with the twinpot calipers and Celica carrier brackets today and all I can say is WOW!!! The braking performance is phenomenal compared to the stock discs and single pot calipers. It gets from 100-0kph in very little time and literally throws you forward in the seat. Very very impressive upgrade, and they look awesome too

I took some quick shots but will take some better shots tomorrow. It's too dark to take any here now unfortunately. I literally just got back from a long drive along straight country roads where I could slam my brakes on multiple times from high speeds to bed the new pads and rotors in:

nice one scott, i cant wait to do this either
