I need new front discs!! I can't find the right ones
After doing brands GP I was putting the car on the trailer, strapping it down and spotted my discs were cracked!!!
So Im pretty sure I have identified them as Cortina mk 3 / escort mk 2. Something like this
https://www.burtonpower.com/brake-discs-f-cortina-mk3-mk4-mk5-escort-mk2-rs-pair-di822751.html
Problem is that the pads were slightly of the edge and were touching each other.
I would like bigger than 247mm. Are the solid Sierra rear brake the same? The offset looks good and they are 257mm
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Aren't the Cortina discs bolted to the back of the hub? The Seirra ones go over the wheel studs against the flange.

Brakes International has good data
I am running with Sierra solids with KA/Fiesta calipers
Unfortunately they are only a 240 diameter, so not what you are after
Take a gander on their site though, you may find what you need...

The rally design discs are modified e30 bmw solid front discs, their website describes them as 265mm, in reality they are 260mm and it does mention it
somewhere in the details.
They are reasonably priced though and off the shelf so might be the simplest answer.
There are also a few peugeot/citroen front discs that are modifiable to fit inboard on the escort/capri hubs if you have the engineering equipment to
do such, I'm not 100% sure there are any solid discs amongst those though.
These are vented versions, but you can see the difference.

This is correct, the cortina discs have a tiny offset, about 1/2" because they bolt to the back of the hub

Are they for sale 🤣
I have old ones to measure. I just wanted slightly bigger than 147mm. Ideally 155mm to stop the pads hanging off the edges.

1.3 Sierra fronts are only 240mm
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

Update. . . I just bought some non grooved or drilled versions from Burton power. Unless I customise them I can't get cortina fitments which are
around 155mm. They don't exist. Annoying as these Raceleda uprights and calipers create a tiny over hang for the pads.
Grrrr

Are the raceleda calipers you have radial mount? If they are, you could get the overhang depth machined off the brackets, and they would still be
adjustable to bigger discs with spacers.

You could try Tiger Racing they have some cortina fit discs on their site and might be able to help with the size you need.
