So whilst I am loving the Puma I do have a couple of changes I want to make.

It is currently sitting on 17s with 205/40 rubber and I think this is just a tad too harsh for the roads near where I live, so will be ordering some new 16" and plan to be shod in 195/45/R16 Michelin PS3s. Is a tyre I have had before and always been impressed, the car will be dry/summer use only so not too fussed about wet performance.

One of the reasons I have gone for 16s rather than 15s is I find the braking very outdated, and as the steering and suspension I have no issues with the next logical thing before I make it go faster is to stop better.

I am considering the Mondeo mk3 upgrade at the front to give 280mm of disc a bit of room under the 16s and fill the gap with just the carrier hole to be enlarged.

Rear wise I have what once was refurbished RS2000 4x4 setup which was modified for a Mk3.5 Fiesta sat in the garage from a previous project. I know the seals etc will be shot as been sat 15 years, so would send the callipers for a full refurb and seals etc. My question is as this year of Escort used similar ABS will the sensors be a direct fit? and also what handbrake to go for? I am assuming FRP which may fit but hoping someone knows the answers. Thanks in advance.

I know rear discs are totally OTT at the moment, but for aesthetics and I do plan more power upgrades later and I hate hate hate drum brake maintenance (too many skinned knuckles) and just the look of them.
Good luck with the upgrades. I don't know re: the rear brakes but you could also check the ST150 handbrake cable as I have vague memories of it being similar too.
I wasn't aware the Mondeo setup could be had with 280mm discs, I thought it was only 300mm like I used on mine which also had 16" wheels. Mondeo Mk3 Calipers & Focus ST170 Discs being as they are the same 4 stud pattern as the Puma.

I could be wrong so ignore me if it does indeed have a 280mm disc available.
Just an update for this, after inspecting the RS2000 setup, it doesn't have ABS or a way to retrofit it easily.

So have obtained ST150 front and rear setups which will be stripped and refurbished.

ST150 calipers also have the same size pistons as the puma calipers (54mm if i remember) so you shouldn't notice any difference in pedal travel unlike the Mondeo calipers which have larger pistons (60mm i think) and tend to result in a slightly longer pedal travel feel.
You are right Yippee had looked at far too many numbers when I posted lol, after a nights sleep I am going to go the ST150 280mm on the front.
Indeed . . . no drilling involved if you use the ST150 setup, straight bolt on . . . get some braided hoses too !
