Like what your planning (snigger!)
Just a thought, and I expect I'm teaching you to suck eggs, but unless your using this potential monster to go circuit racing, I wonder why your going to the extent of such big brakes ? (apart from they look cool, you can, they will stop a tank) You motor should, even with the V8, still weigh in less than a cossy sierra, and they could regularly stop from 150mph. Your going to probably increase your unsprung weights, and the sort of tires you will need to actually tranfer all that braking power into more than just rubber smoke will probably not be road legal ! Also you will have to beef up the suspension to keep the hubs on the car I suspect!
Please don't think I'm having a dig, I'm just interested in your reasons for doing it.

Hi Tony,
I'm not taking it as a dig at all
You are quite right, I could use smaller brakes but your reasoning why I shouldn't use the larger ones doesn't stack up in my mind. Here's my thoughts and reasoning, see what you think...
Firstly, yes they will look cool and yes I can
They will actually decrease unsprung weight, the calipers are half the weight of the std 4x4 Cosworth one's I have fitted right now. The discs are about the same weight as they use an alloy centre.
Have you ever tried slowing a Cosworth from 150mph quickly on std brakes? I have and they dont inspire confidence!
225 width tyres will easily handle the braking power, I have used narrower tyres with the same sized brakes on a similer weight car and not had any issues. We sell lots of 362mm 6 pot kits for 2wd Cossies and they run 215 width front tyres.

you don't need to stop if your gonna struggle to get off the line in the first place
what are you doing about traction?? no 195 - 245 width tyre is going to cope with that little weight over it
iam going to try and retain the traction control from the omega on mine, your going to have your work cut out Martin, going to be very interested to see how you overcome this
I actually don't see this as a problem, the car at the moment has 245 rear tyres but I could get wider on if needed.
I can give an example of light car/big power .. My mate has a Westfield fitted with a 450hp Cosworth YB turbo, it has 235 rear tyres and it recorded (on proper timing gear) a 0-60 at Bruntingthorpe of 3.5 secs, thats a barmy light car that gained traction.
I was also told that our 340hp Audi powered front wheel drive MG ZR would have no hope of putting the power down on 215 width tyres, that has not been the case.
