It just occurred to me that I actually saved exactly the quotes you're looking for in my tire info .txt because they seemed like very useful information to keep for reference. I got the impression at nats last year that 996 GT3s can only fit 245 up front.
Summary:
Alan Pozner: "285s fit on the front of 987s (and 997s) just fine in stock form."
John Vitamvas: "Dave Hedderick had 285s on the front of his dad's 986S at the 2008 Nationals."
internet tough guy (not sure real name?): "Rad had 285s all around on his '08 Cayman S in AS that won AS this year at Nats. I've been running 275F 285R most of this year but will be going to 285F for next year. They actually fit better than the 275s "

Real data point for 987/997 front fitment. In stock form, with stock limited camber, stock offsets +-6mm, 285's will stick out of the fenders, but will work because the ride height is so tall, and the tires never get close to contacting anything even under compression.
With ST/SP mods, the limit to fitment is a non issue. Use camber plates to pull in the strut tops, and 285s will tuck in the fenders at low ride heights. Your limit is inboard strut/spring clearance.

You can fit 285s in ST. Ran 285s in front of the 996 GT2 years ago on 10" wheels. CCW has the dimensions I used.
Think I was running about 3 degrees negative camber, and I never had any rubbing in the front, and did not need to roll the fenders, etc. (I was running in ASP, so I could have).

I don't know if people are still looking for this, but my 40th was 3180 or so. It could be lighter with manual seats instead of comfort, and no rear wiper or nav.
