Looking for recommendations for a fast road front brake upgrade kit for an 850. I installed OEM 302mm disks and police pads a few years ago but it's about time for replacements now so I'm trying to work out my options. The AP 325mm kit seems to have been the way to go in the past, but that doesn't seem to be available any more now.

I'm afraid I'm not very clued on on brakes, so in basic terms should I be going for 4 or 6 pot (I assume 8 is overkill)? Fixed or floating? And what brands are good? I want strong but reliable, the car hasn't been on a track yet, and even if it does it would still be going back on the road afterwards. Better is fine, I don't need nor can I afford best.
