EOI: 294mm disc and twin piston brake upgrade

[mrcyborg]

hey guys,
I am looking into doing a couple of kits for brake grades.can do at least one if not two or three of these.
will be bolt on calipers, they take the normal db1223 size of evo/fto/magna.

i can supply the calipers for 400 for the pair, in very good condition off working vehicle, these have been pulled down and checked.

i can also supply the discs to suit, they come as a 5 stud disc but i can have them drilled to suit 4X114.3 or 4X100, i can get them in current stock of DBA4000 series slotted rotors including redrilling for 500 for the pair.

obviously postage on top to where ever you are.

the discs are the late magna style discs that have much better venting setup than the 276mm items. they have vents on the inside of the disc also, will see if i can get a picture of them.

the calipers have the banjo bolt setup of the gsr/evo so suit better to these later models or CE models also.

this requires minimum wheel size of 16 inch, haven't found any rims smaller to fit.

any questions let me know.
just looking to see how are interested and if its worth me buying several sets to try and get a better deal.

cheers simon.

So is it with the same caliper as early evo/vr4 (well they are very similar) and just bigger disk.
Or a better caliper that uses the same 1223 pad?
Isn't this off late model magna's? (the ones after the 276mm twin pot magnas, like the ralliart and awd magna's?) pretty sure they used this stuff when i was researching. Or gto calipers?

 

[mrcyborg]

not the same caliper. but it is pretty much the same, the advantage isnt really in the caliper itself, more so a better design disc and larger diameter with better cooling.

 

[xjokux]

damn.. would this would fix the brake pad issue?

will i be able to bolt on my current vr4 calipers to the new rotors or not?

awfully tempting but im in love with my 15"

 

[mrcyborg]

what brake pad issues?
these are different calipers, they just take the normal pads.
16inch only or larger.

 

[xjokux]

you know how our modded twin pot setup, the pad sits 3-4mm off the rotor or more so pushes the calipers further out.

i'm not trying to be negative, but the db1223 pad is designed to take a 276mm caliper. any radial difference will create heatspots and uneven surfaces on the rotor.
2-pot brakes are generally $150-200 these days, plus $200 for 4-stud rda rotors.. which makes it a far easier and effective option.

xjokux, our setup on the cb gsr is only different using the spacers behind the caliper, this is only due to how the hub has been modified. the bit on the inside of the disc that doesnt get worn is standard over all the models that use this setup. its just how the disc is made.

NK, granted yes the 276mm setup is much more common, cheaper yes. this setup comes as a factory setup, so the db1223 pad comes also standard on a 294mm setup so i am quite sure it has been well tested, the extra area of the 294mm disc is better obviously due to size, but the why this disc is made also gives it much better cooling as it has a channel on the inside of the disc also.
like anything if its more common its cheaper, i can get 276mm discs for 30 bucks and have them drilled easy. so they can be had really cheap. this is just a different option, its bigger and more area which is the whole point of an upgrade, and also where the twin piston caliper is better is it doesnt require huge wheel offset as you require with 4 piston upgrades.
also take note these calipers are not the normal vr4/evo/magna twin pot calipers which can be had cheap.
i run the 276mm setup on two of my cars currently and only swapping one to the 294mm setup due to running 15inch wheels on one of them.

Is this a four piston set-up that will bolt directly onto an Evo 3?
ATM I have OEM Evo 3 front brakes and desperately need an upgrade!
I was thinking about the 3000GT front calipers and bigger discs as my mate haas gone this direction and is very happy.
The price has put me off this though as the conversion would be around $2k after I got the 2nd hand calipers re-kitted, buy new discs and get them re-drilled, get custom mounting brackets made etc etc.

 

[mrcyborg]

twin piston as the title says, cant get a straight bolt on setup in four pot without going complete aftermarket.

 

[7zark7]

Ok so do you have the mounting hardware available for the calipers?
Is this a fairly easy upgrade or will I have to get items custom fabricated etc?

i was referring to how the actual pads sits 3-4mm off the disc and doesnt get wore down.

 

[mrcyborg]

xjokux: bit confused about what your talking about then mate? maybe a pic will help.

7zark7: this is complete bolt on, i supply the calipers that bolt up to your hubs, and then the disc redrilled to suit.

Not sure what you mean either as I did this conversion to my Magna and had no wear issues with the pads and by F***K didn't it pull the car up. It used the same pads as the earlier twin pot running on a 276mm disc. The main difference from what I could see where the pistons were bigger the bolt spacing is wider and the disks have much better venting.

Been looking at doing this but as said need 16" to fit over calipers, although when they rallied the AWD magna it was fitted with 15" steel rims.

Cheers

xjokux : sounds like you are using twin pots with the wrong rotor if the pads go over the side of the disc.

 

[7zark7]

Thanks for that MrCyborg.
Can you put some pics up so I can get a better idea of what the units look like?
Cheers,

 

[mrcyborg]

will try and get some up soon.

i didnt notice this till i got the wheel bearings replaced. these are vr4 calipers

 

[mrcyborg]

hrmm ok, confused now, never seen that before!! you have the modded cb gsr hubs dont you?

oh yeah, and thats not right,

 

[xjokux]

so was i, unless the calipers are bigger and from something different. The guy i got them off said they were a vr4, it bolts on on fine too.

as to4garret said seems like the disc are too small.
