I made the switch
What alignment specs and why the roll bar change? (what bar specs?)
Early feedback on the differences on the street are mostly on power delivery and sound. The power is impressive, the lightweight flywheel racecar fast, and the sound of the engine with the sport button on, is almost italian in tone and is sooooooo addicting. Can't test true handling until the track. Ride is really tolerable (dare I say comfortable) on the street. Easily as compliant or more so than the 996. Still working on being smooth on throttle blip when heel toeing, esp in sport mode (big adjustment from the 996 with stock flywheel). In sum, simply awesome. To me, the 996 feels like a slightly detuned race car for the street while the .2 RS feels like a race car that happens to be street legal.

For alignment, check your rear toe -- the 997 uses a LOT of rear toe-in, not a little.
I'd start at -2.0 front camber on Sport Cups. I tried -2.2 and found -1.9 to bring higher apex speeds ... given Mac struts and zero camber gain and almost zero body roll, the experience in the 997.1 RS is not directly applicable to the .2 RS. At -2.5, you'd start to bring on inside shoulder wear on the street. In any case, caster won't change.
I'd recommend getting the connectors from the dealer to build an exhaust divertor valve bypass switch (look for posts by mikymu on this ... it's easy and sonorous.)
If you ever wanted to have the 996 GT3 speak in full voice, just bypass the side cans and you have the real machine ... I've never driven a water-cooled 911 that sounded better than the 996 GT3 with the bypass. The 997.1 and 997.2 GT3's sound great outside the car, but still have a hint of "Boxster" in there. The divertor valve bypass switch goes some of the way to improving that sound, but I think you have to pull the the mufflers entirely to get to the real sound track in the .2 GT cars.
Overall, from what you've said, I'd encourage you to go ahead with the safety gear and leave the suspension bone stock for your first track day. You'll be astonished by the apex speeds and braking performance. As you note, on the street, there's no way to access what the car offers, no way to get heat in the tires and no way to take the car to 100 mph+ in a straight line, let alone at the apex of a turn! : ) Once you have a feel for the car and your own limits, then you can set to work on where you want it.

for $150 it could be another (albeit pricey) solution ...
