Brembo rotors / 99 spec?
Just want to know if these 313MM X 32 MM ROTOR WILL FIT 99' caliper?
what is annulus :44M ( brembo spec size /see link)

Annulus should be the width of the swept area....have to measure it, but 44 might be slightly narrow compared to standard, you'd also have a very slight pad overhang on the OD if using the standard caliper.
See you were after Spirit R rotors previously too, there is apparently a separate parts list for that and the version VI cars. The undrilled front rotor goes by F124-33-25XA - possibly, there might be a change in the XA suffix to get drilled. One local car had a catastrophic failure of these discs when used in anger, 290kph > 80kph stops - and heard of others with incipient crazing through the holes after track days.

assuming rotor will be slight smaller than pad, will this affect performance?

The FD is not overly endowed in pad area to begin with, so I'd personally not want to have less of it working. Measured the 17" rotor, the working area width of that is 52mm....the 16" rotor being wider for some reason. Pad widths seem to vary between 49 to 51mm depending on brand.
Coleman mentioned they'd be prepared to make a bolt-up or full floating disc a couple of years ago if they had a sample - further afield from Germany, DBA Mitsubishi Evo 5000 series rotors, 320(?)x32 have been used here and also the Project Mu ones are a bolt on proposition if you have the coin.
