I'd also replace the greenstuff pads as I didn't like these in my Ultima either, lacked cold feel for road use.
Maybe do the masters first to see the difference.

MC and caliper Sizes
Here is the spec of my car.
Front MC 3/4" bore
Rear MC 0.7" bore
Front caliper 4 x 25.4mm pistons, 280mm disc, Mintex M1144 pads
Rear: Caliper and disc is Seirra.
Wheels are 15" with 195 tyres.
What I can not remember is pedal ratio but I do recall it being on the minimum recommended. My pedal is rock solid and I can lock the wheels at high
speed.

I've got some Hawk Plus pads which I can swap over if I feel the need but I will do the masters first as you say.
You still in SA Andy or back in the UK?

Fairly similar to my setup except your caliper pistons are even smaller. Either you must have a larger pedal ratio or leg muscles like Arnie

I have just swapped the master cylinders for smaller bores and this has transformed my brakes - now they actually work!
0.625" Front & 0.70" Rear works much, much better than the 0.75" front & rear which was originally supplied. Obviously this
might not apply to everyone's setup so its best to check with some like Rally Design to get the best combination of calipers & master
cylinders before installing them - replacing master cylinders on a completed GT2 is definitely not a job to do when you have a dodgy back

glad you got it sorted Raz
What did that front brake setup cost, and where from?
Cheers

The fronts are Wilwood Dynalites which I bought on eBay for a silly low bid (which I didn't expect to win) Probably about half the cost of
buying new.
Your Excel spreadsheet was just the job Fred
