 AW11-3SGTE brake upgrade
|
Wed, 31 August 2005 09:33
|
 |
I am coming to the final stages of my engine conversion to a 3sgte. I need to upgrade my brakes all around to the same specs or better than the mk2 mr2 turbo that the engine came from (according to my engineer)
What upgrades are possible?
The car is basically a standard supercharged model so I have those brakes at the moment.
I have seen the document for the GT4 front brakes... are there any other options?
Thanks for your help!

st185 gt4 single piston calipers with redrilled st185 gt4 discs to suit a 4 x 100 pattern basicially you just drill one hole to convert it and it will fit no caliper spacers etc needed

as above 
i am currenty running ST185/ST165 Twin piston calipers on my aw11 using the standard rotor. fits perfectly and pulls it up a treat. by the end of the week ill be running the above setup hopefully. using a st185 single piston and larger rotor.
if the big single works as well as the twins or better it is definantly the preferable option as your pad choice for the st185/st165 twin piston caliper is a little limited. hence why im changing.

AW11 - 4AGZE-SC14 brake upgrade!
|
Mon, 19 September 2005 00:41
|
|
Hi,
Though not a 3SGTE, I have some SC14 mumbo in my AW11.
Are there some twin piston ST165/185 front calipers that are a direct bolt on to the AW11?
How much better feel/braking than stock? Hard to get brake pads?
Disc-wise what needs to be done? (My front rotors are warped and in need of replacement anyway)
Cheers, Nick.

as above 
the twin piston st165/early st185 will fit on no worries at all. straight fit up bar trimmming a little of the dust shield out. rotor wise they are a perfect fit.
pad choice is a little limited though as EBC dont make a green stuff only a standard and bendix only make a metal king. QFM should be able to whip you up smoething. and trd have discontinued pads for them.
the later model st185 single pistson which arrived to day i willo be getting set up on mine hopeuflly they will work even better. and have a greater choice of pads avlaiable. they use a larger 278x26 disc as opposed to the aw11/st165 which uses a 258/22 disc..
so watch trhis space and ill see how the singles go.
that said the twins pull up fantasic

i will be doing this aswell on my aw11. I have had the st185 calipers for some time and have just rebuilt them with new seals and some new red paint. They are looking pretty smick atm and cant wait to get them on the car. Need to fork out for some new rotors tho.
You will need 15" rims atleast to clear the st185 calipers im not sure about the ofsett tho..

Looking forward to hearing about the results.
Can you guys pls tell me what an average price is for the ST185 calipers.

mine cost me $150 and the rebuild kit cost me $80 from toyota.
The price for rba slotted is $130 each for st185 gt4 discs which in my mind is not quite as good as dba but at half the price of dba slotted in my mind it isnt worth the extra $130 for that bit extra. Having said that if you can find some dba's at trade then by all means go ahead and buy some.

the brake bias will be out you can fit brake bias adjusters just check with your engineer as to which ones are legal. Im sure that cabin adjustable ones are.
Also you will need to check with your engineer about whether he will require a master cylinder upgrade but im going to be using the stock n/a brake booster

with my twins i didnt use an adjuster. the bias was brought forward a bit but i felt this was a positive and made the car more controllable on less then perfect surface. i always felt the aw11 had the bias a ;little to neutral and not forward enough.
im not sure what the story is with the singles but my engineer approved the twins no worries without a bias adjuster.
truth be it known if you didnt know and i mean really know what you were looking for you wouldnt even notice the differenece unless you had them side by side. and with the teardrop wheel i doubt you would tell at all given how little you can see through them/.

I am reading this thread with interest as I am currently running the same calipers you guys would have had as stock on your AW11's (mine are on a KE25).
If someone who has the following calipers not fitted to a car: standard AW11, ST185 twin and ST185 single it would be great if the piston diameters could be measured up and posted on here as that is quite useful to know.

An engineer will only ask you to fit an adjustable bias adjuster if the brake bias is not acceptable i.e. rears locking before fronts.
I am keen to find out the size of the ST185 single piston caliper piston diameter as it would be a simple bolt on upgrade for me

Seriously that much bigger, I await the measurements with anticipation.
I just had a look at the DBA website and it looked like the ST184 also used the same calipers as the 185??

We are talking piston diameter?
If so, I guess the 184 could be another option for me if i need to reatin a piston diameter close to thw standard AW11 size but want the 278mm rotor

yeah thats what i thought 10mm bigger substantial difference would be nice if it had twin pistons but i think with the power i intend to make the extra thermal capacity of the st185 discs will be of more benefit

St205 brakes can also be adapted up to the front , in the same manner as the St185 ones can be - you just need to space them out a little more and machine the rotor down a smidge ..
These are the ultimate " bolt on " setup - but good luck finding the calipers

thats what i was about to say so they arent really a bolt on option it would probably be easier to buy 4 pot nissan calipers and get brakets made to space them properly

Hi Toof,
If/when you're happy with your ST185 brakes, I'd be interested in buying the ST184 twin pots off you and giving them a go.
Cheers, Nick

your the third person wanting to buy them lol
but again... sorry they are already spoken for. my gf wants them on her car.
i measured the rotors ive got atm and they are pretty much on minimum thickness. so save getting these ones redrilled i think ill get some new items instead of redrilling almost cactus items.

Hehe,
No worries! I better hang on and hear how those ST185's go.
My front rotors are warped so I'm hanging out to do something soon on a budget of course.

DBA743
standard is $150
sport slotted/cross drilled $219
from www.discpads.com.au - some of the cheapest bendix and dba stuff you'll find quick to get things sent out too which is nice
ive got a mate that can get rda pretty cheap so ill go and talk to him and see what he can do.
i have rung around and been quoted $40 per rotor to get them redrilled !!!
what im goign to do is do a dodgy home redrill job on my worn out rotors so i can mock them up and check sizing etc.

yeah i was quoting slotted prices i dont think ill bother with just standard
Sounds like a good idea to try it at home first i think $40 is a bit steep considering all they do is measure it up and drill a hole!! it would take 1/2 an hr at the most.

15" should fit. given the caliper isnt particulary wide and height wise they fit under st185 15" wheels... so i assume they should

Hi,
Are the ST185 'big single' calipers a stright bolt on to the AW11?
(I know the discs are trickier to sort out)

they will bolt onto the hubs but you will need the st185 discs to be redrilled to suit a 4X100 pattern
