Have been asked about the supplier:
Living in Denmark I need a TÜV approvement, which BIRA
was not able to give. Next step was to try to use struts from
a later/other model, and Audi USA were wery kind to describe the conversion from UFO to G60 using original rotors.
But I happens to find http://www.movit.de/
which made the brackets for the calipers and the hats for the rotors and delivered it as a kit including 4 stainless lines (for the back too) and the necessary papers for Street legality.
It is a bolt-on job on original struts and if needed /wanted for use of 15" for winter it can be reversed in a few hours.

More or less force?
I have some results from exchanging my UFO's
(newly rebuild) to Porsche GT3 Monobloc 4 pistons
on 322x32 mm crossdrilled and vented rotors
a) Before: 60-0 Mph 155 feet
After 121 feet = 38 meter
(Porsche claims 35.1 meter (100 km/h)
b) Same foot-feeling. Same foot pressure for braking
c) Bias between back and front were not adjusted
d) Breaking at new fallen snow 2 km/h (with ABS on) shows
equal breaking front and back (analysing the slip marks)
e) Breaking from 100km/h ABS off = blocks front
f) Breaking at ice/wet skid pavements from 60km/h :
ABS OFF gives double braking length and NO control at all
(more than 100 meter) compared to ABS ON.
I was given the option of Porsche Bi-turbo instead of the GT3 Monoblocks - same price -
but advised, that the Monoblock is
1) more rigid,
2) caliper shorter giving more cooling air to the rotor
3) the pads a bit bigger
Have to use 8x17 for both winter and summer
Finally: I don't do much about polishing my car
but the brakes are high admired at track events by
both competitors and publics
