Probably better.
The set of PS2s that lasted 2000km wore out the driver's side left (lots of right hand turns). More camber corrected that problem.
More negative camber will make the car very responsive but somewhat darty. Something to keep in mind.
If you really like DEs consider getting a track only car. No use butchering your cab and making it uncomfortable on the street.

I know that neg. camber will wear the inside of the tire more on the street. I just like to know if it'll shorten the life of the tire by how much? Is 10% a reasonable guess?
Pyrometer is a great idea. Do you like the surface measure type or do you use the "poke" in the tread type?

I've seen the "poke" type break, so I use the infrared type.

I really enjoy DE and the car is very capable.
But now I am looking into tires, camber, suspension etc.
Soon, I may want to time myself and time trial is a whole new ballgame. They want cage, seat and 6 point belts etc. which is difficult to mount in my cab.
Somebody stop me before I get too deep.........

Not being able to drive home from the track with the top down would indeed be a compromise!
But before we start yet another cab/coupe thread or dismiss the many Boxster DE'ers, on this we should easily agree...
No other marquis navigates this particular compromise better than Porsche...

KW - I have been tracking a 997S for about 1.5 years now. Prior to that I tracked a 996GT3.
For the 997S, getting the 997GT3 control arms put in on the fronts is one of the "must do's" for this car on the track. Best front negative I camber I could get before the control arms was -0.8. I know run -2.5 on the fronts and -2.0 on the rears (nothing needs to be done to the rears to get that camber). My drive to work is quite short so I am not worried about this type of camber for daily use. This set-up totally alleviated the tire wear issue and the control arms give you a bit wider stance on the front of the car for more stability. Another important mod, and cheap, would be GT3 air ducts for the front brakes. After that a good racing brake fluid, harness bar and harnesses, a neck restraint, and the 996GT3 club seat and you are good to go. I have done all of this and am now completely satisfied with the car. If you want to do more, you should start seriously thinking about a dedicated racer.

you are in east bay, do yourself a GIANT favor.
drive the car to tony at tcdesignfab.com. tell him exactly how you drive, how much track time etc... he will set your car up with less tire wear and faster lap time.
based on your track mileage, anything over 2deg camber will really chew up your tire. in fact 1.5F/2.5R is about all you need. and if you add GT3 control arm or shims to get that much camber, i bet your stock suspension wont be able to optimize the camber/usage. there are too many variables in suspension set up. rather than having a bunch of us guessing, you need a suspension pro to figure it out. i have tried to dial in kassumal setting, track setting on manual... those are just starting points. HOW YOU DRIVE, is what's important. my car for example, i have some very experienced drives driving it, one tells me it's neutral, one find it lose, one thinks it pushes .....

Looks like ECS has it figured out with the GT3 arms and ducts.

What Bob says is true. I experienced what is happening to you before I added more camber.
You can install the GT3 bits as some guys have done but my mechanic elongated the adjustment area by drilling it out (proper terminology escapes me at the moment) to allow for more negative camber. It worked.
