Don`t bother ,fit the cosworth set up or better still the after market ones.Cosworth are 278mm discs and you can make the kit up for peanuts.

If you are going to use Cosworth discs then you will be better off with the 2wd (rear wheel drive) Sierra Cosworth versions and these are 283mm dia. The 4x4 Sierra and Escort cossie discs are 278mm dia but are the wrong offset.
A set of the single piston 4x4 cosworth calipers with the 887 and 888 casting on them can be made to fit very easily with the 283mm dia RWD Cossie discs.
Ive carried out this conversion twice now to different cars, and a set of these are currently nailed to the front of my Griff 500.
Hope this helps.
Cheers

You can purchase the complete kit from hans ,new calipers carriers,OE discs pads and two small spacers or build up the kit your self.Thought the 283mm discs have to be
machined down and still fit a washer instead of the larger spacer.

You can get the discs machined down to fit, or you can do it the easy way and file out the caliper carrier to clear the 283mm disc. The difference in the diameter of the discs is only 5mm, so you only need to file approx half of this (i.e. the difference in the radius) off the caliper carrier to get the discs to fit.machined down and still fit a washer instead of the larger spacer.

You also need a 1mm spacer (or large flat washer) to be placed between the caliper carrier mounts and the hub so that the carrier is spaced equally either side of the disc.
If you are going from 240mm dia discs to 283mm dia discs then its a good cheap upgrade. I did this on my previous car (Cobra Kit car) and the difference was amazing for the cost.
