Different calipers probably as there are big differences in size of calipers depending on make and size of piston early B2's had 54mm piston and these calipers are smaller than the 57mm or 60mm single piston ones fitted to later cars.
I have a pair of sport 295mm discs (machined on hub outer face) and some front boxster brembo calipers to go on my UR when I finally get round to getting it back on the road, they came off another ur running standard 15inch wheels so I know they fit but clearance is very tight, remember the extra 7 mm (288 v 295) is actually only 3.5mm closer to the inside of the wheel, problem is getting calipers with sufficent clearance to fit over the discs.
On my B5 1.8tqs A4 I upgraded the 288mm discs to 312mm using A6 rotors and early S3 carriers but kept the standard A4 calipers (57mm) as the S3 uses 54mm calipers which look physically much smaller even though they take the same pads.
