I'm playing mechanics tomorrow, will have my wheels off the car and I have the Brembo brake upgrade with 324 mm focus discs 
I could take a measurement out from the centre of the hub to the outer most part of the caliper if that would help
Great brakes by the way.
Those brakes will need a try out, how about joining the Marlow Group at Snetterton on the 26th September?I could take a measurement out from the centre of the hub to the outer most part of the caliper if that would help

I'm supposed to be doing Hethel around that time but even that's looking unlikely 
I'd love to
I do need to try them again on track as I've cured vibration by just wearing them in and they are now consistently outstanding on the roads,
But only a track would work them hard enough to really find out. Hmm!

I haven't got a decent set of scales,
The Brembo calipers are a lot lighter than the originals but the bracket is heavy and the discs are slightly heavier than standard,
At a guess I'd say there's not a lot of difference overall.
Going by how the car drives, I can't feel much difference,
other than the brakes work very well.
I haven't got enough time available right now to remove caliper and bracket but this is an important point ( un sprung weight) I will make an effort to weigh them at some point.
I do believe the Brembo set up is very slightly heavier going by bounce over bumps, I have twin adjust shocks so it's not an issue, as long as you have adjustable shocks one click up seems to dampen out any issues.
It's marginal at best, IMHO
The difference in brake performance across the board is as you'd expect from such high class calipers, puts the car into another league.

Anyone able to post up the weight of one of these 324mm Focus discs? That's a big slab of iron!However, the Brembo calliper is a lot lighter than the standard cast iron mono-piston lump that came with the car as standard, while this offsets the heavier disc element to some degree I'd say overall the whole setup will still add in the region of 15-20% weight (but that is a complete guess).
To compensate I went up 2 clicks on my front Gaz Gold Pros, this proved too much as the ride became a little harsh and the front end was fractionally more skittish on rough surfaces.
Yesterday I backed them off one click, so I'm now effectively one click up on where I was with the standard brakes, so far after a spirited drive and some slow speed rough surface roads this setting seems spot on. The bottom line is while the Brembo conversion will add a bit of unsprung weight (which as we all know is less than ideal) the truth is you really don't notice it on the road with the right damper setting, all you notice is a massive improvement in the way the brakes perform and feel.
Two piece discs are available which will completely redress the weight issue (if you can call it an issue), but they are expensive. I may consider this in the future but for now I see little point as I'm still enjoying what is a fantastic upgrade for the right money.

Or just go bells and rotors
You wouldn't have a pic of said bells and rotors would you Here's mine after about 3500-4000 miles, wearing nicely now.
I have the same Brembo E38'road pads as Chimpongas
As a rough guide as I'd rather you measure your own brake set up!
From the centre of your hub out to the furthest outer part of the caliper is
175-6 mm
7 inches or 178 mm would clear the caliper but only by fractions so anything over 14 inch inner wheel should just do it but I'd suggest 14.5 inches as a safe bet.

Yes 
Reyland two piece 330s against the 283s that came off; and then behind 17inch wheel with AP Racing 4 pots - also put 300s of the same type on the rear with the stock calipers on bracketsGo on, someone weigh the Focus one piece manhole covers

I used this template to see if the Brembo's would fit under the 16" splitrims but they don't so back to looking at 300mm options....
