You can get a calliper extension from dax cars for about £25 it fits the standard sierra hub.
It enables you to use the standard calliper with a slight mod. If you do go down this route check with dax, Can't remember if it was 2wd or 4wd
Cosworth discs that they use.
Not sure what you are doing but it might be of some help.

On a locost or mkindy I'd be very suprised if you actually benefitted from bigger disks upfront. With standard disks, calipers and some decent
pads you should be fine. Also bear in mind bigger discs will be heavier and will add to the unsprung mass of the car, thus adding detrimental affects
to the handling. Either way I doubt you'd notice any difference. save your money and spend it on another part of the car!
If you are dead set on imprving the brakes you'd get a better improvement by spending your money on some nice light wilwood calipers.
just my 2p..

yeah, would agree with ned!
Saving my pennies to get willwoods, as a nice four pot conversion can be yours for under £400.

how do the bigger disks, pads and calipers add to the unsprung mass of the body ned? they are attatched to the hub remember and this is sat between 2
wishbones connected to the body, so really, the disks, pads, calipers have nothing to do with the overall mass of the unsprung chassis/body combo
just an observation

simple, they add unsprung weight, lighter brakes is defo the way to go on such a light car...........

ohhhhhhhhh you piccy iccle bugger, as bad as our lass.........
seriously though there aint no need to go over the top on braking, quality light weight calipers, small discs and good pads, bigger brakes may not
even get up to temp and prove less effective than standard set ups

Graceland, the unsprung weight of a car is the weight of all the unsuspended components, namely wheels, tyres, brakes, hubs and a portion of the
suspension arms. The lower it is the better since lower interia and momentum means the suspension can react quicker and more accurately. At least
that's how I understand it, I'm no chassis engineer though (well maybe an amateur one  ).

And I understood it to mean exactly as mackie has just described.
The rest of the car is sprung mass-i.e. the 'other side' of the springs (or in other words, the bit of the car that is held up by the
springs....).
Dont just build it.....make it!

I used 2wd cosworth discs and 4pot calipers on my rally car. The discs are flipping heavy and I wouldn't want them on my locost!
