Be interested to see how a Brembo compares if I could keep the same disc/pad and the rest of the system.
They are night and day like, I would say it's got at some something to do with the car they're fitted to.

Also, steer clear of Hispec. Ian has them on his Puma and they are poo compared to my brembos with same pads and same size discs.
I think there's more to it than that - bed in procedure and master cylinder size/capability being two variable factors which could affect things.
I don't buy that a caliper of one brand would be that different to one of another brand, there is not that much variation in the design surely.
some guy on puma forums reckons his wilwoods lock his r888's up easily on a dry day, hes running standard stuff apart from the calipers etc, i dunno we willl have to see my experiences that will give you a better idea
i personally think it could be down to a pretty inefficient setup in the puma

My Wilwood calipers are really wide, the only wheels in the correct offset was Comp Mo's, that fitted.
My mate fitted 300zx 4 pots to his Escort Cab he also had the same wheels as you, and they clipped inside of the wheel. He's now got some rally wheels don't know the make, but they clear fine.
Just something to keep in mind.
I've got 280mm's on my throttle bodied XE and they're great on track.

being able to lock wheels up isnt a sign that brakes are good - just a sign that they can lock up 
He may be running stupid front geometry, no/little bias to rears.
Our standard R32 GTR calipers (4pots and 300 or so discs) were CRAP when we got them.
Changed discs and pads - no great increase in performace.
Stripped and rebuilt the calipers, fitted master cly brace and tried again - MUCH better pedal feel and general positive braking.
Ian - were your calipers new or second hand? If second hand or even if new - are the pistons moving freely or are they a bit sticky? Pop the pads out and get the pistons moving back and forth
Are the pads glazed? pop them out and check. We've had a couple of sets of DS3000/2500 that have glazed over - short term fix was to rough up the surfaces wouldnt recommend this if you want to keep the discs etc and it'll give a bit of uneven wear I think.

don't worry about clearance I'm getting diff wheels plus the they are spaced 15mm at front and 20mm at rear

i did this with mine, no difference, the puma setup really is that crap
edit - didnt brace the servo

I struggle to lock up decent 888's in the dry with my Impreza brakes  they are very effective. I would say my brakes are WORSE if I lock up easily.
Fee locks up the front over bumps on track, never full out lockups on 888 (she has ABS though so ignore me )

anyway my biggest problem is going to be diamter wheel clearance the guy gave me measurements over the phone, said dimension from the edge of the disc the end of the caliper was 340mm i think
16" wheel diamter is 406mm, what does that leave me with to play with clearance wise

bearing in mind that the 16" dimension is edge of rim, not internal
if edge of disc to end of caliper is 340mm then total clearance needed is 380mm?
based on the fact the discs are 300mm, so the caliper must add on 40mm, you need to add that to both sides?

Wilwood dimension quote 340mm, from opposite edge of disc, to the edge of the caliper.
If the disc is 300mm then that must mean the caliper adds 40mm onto one side. But you have to add that 40mm onto both sides dont you, there fore 380mm

work using radius, it should be easier....
Saying the disc is 340mm edge of disc to caliper suggets that its 40mm extra for the radius.
So 150+40 = 190mm'ish
radius of wheel clearance = 203mm
so no probs on clearence against the inside of the rim
Its the spokes you will need to worry about

Why?
You only have 1 caliper per wheel 
Or am I thinking in the wrong direction here
Are you talking WIDTH? not radius

spokes wont be an issue offset is at least et28 thats a good 7mm out from standard

7mm isnt much, the new calipers will be a fair bit fatter.
Radius - Why would you add on 2x caliper sizes to the overall size?
The disc is 300mm DIAMETER.
The disc + caliper is 340mm OVERALL width/height/'diameter' but isnt centered like the about 300mm
See where i'm coming from?
The majority of the caliper body is in the same space as the disc.

not strictly true, 203mm radius is based on 16inchs, the inner of the wheel wont be 16 inches, its going to be close i need to find exact measurements of inside of 16" turini if anyone will oblige lol
bloke at rally designs seemed to think i would need 350mm to clear, surely he wouldnt be silly enough not to factor in the caliper clearance effects both sides of the discs, unless he gave me the dimension wrong and its 340mm across taking into account the caliper all the way round

looking at turini spokes they look quite good for housing brakes they go outwards slightly.
i really need to ring matey tomorrow and find exact dimensions

i giving measurements on the figures you provided
300mm will be fine on 16's you nugget ITS THE WIDTH YOU NEED TO WORRY ABOUT.
I used to run 15" with HiSpec 300mm 4 pots

if its anything to go by the 4 pots fit ok, will the 6 pots be any fatter you think? i would have just thought longer

ask for somesort of template to cut out and place in your rim.
I know they exist for KSport so cant be that hard a task for more prominent manufacturers.
The discs will be on bells, so prob spaced out a touch compared to standard 1 piece discs... then any extra caliper width.
Ask for somesort of meaurement of its width from a constant mounting point.... i.e the hub.
You'd also need to know the width of the bell to add on for measuring the spoke clearence.
Make sense - this shit is awkward to explain without a wheel and brake in fron of you

thats why im going to check all the measurement before i buy anything matty g 
worse case scenario is a bit of spacing, no biggie
