Just another thought, if you're really concerned about the possibility of a disc fracturing, I'm sure someone on here can work out the
shear strength of a 5mm disc - personally I'll be gobsmacked if it's not at least 3 times what you could ever actually put thro' the
disc in braking terms!
I could have done it for you at one time, but my college days are a few years ago now!
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

If the callipers are two part, can you not just put an alloy spacer between the halves.... some car brakes come like that as standard!!
That way you can use the bike calipers with a slightly thicker disk??!?? Would make it easier to fit a handbrake mech as well if there is a little
more space to play with!

My effort here
9 mm discs, which I plan to use with early golf GTI rear calipers
Cheers

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

I don't think fracturing would be such a problem, more likely to warp.

weight from 100mph... The twice as heavy 7 has to do 135mph to use the same energy to stop.
But the bike has the discs completely exposed for maximum airflow around them, a car has then shrouded within a wheel.

I think they would probably warp like a bugger. Decent sports discs are fully floating to reduce the chance of warpage. Bike discs can warp under
normal enthusiatic use let alone the extra few hundred kilos of a car. I remember back in the late 90's is being not exactly unusual on some
sports bikes.
On top of that, plenty of bike calipers are buggers for seizing and requiring new seals every few years (and that is with regular cleaning).
I think using bike calipers may well be a disaster waiting to happen. As mentioned, brakes are the thing that stops you going splat (and the person in
your way). Its something I would *really* not under engineer.
Certainly I wouldn't even try it on the road without some proper investigation from an enginering perspective. You can say "sod that its
too dangerous I think", but you can't do "yeah you can probably do that" then stack yourself into a tree as the brake fluid
boils over and the discs are juddering like its ABS.

You should have a look at a Pilbeam, that said, they are designed for about 60 seconds use at a time on a hillclimb!
