Both answers are correct, IMO.
First, ask yourself two questions:
1) Am I really going to get in to this a lot? Is it worth the
changes in "street-able"
ride comfort and
cost to alter my car's set up for track driving/AX driving.
2) Should I spend more time learning driving skills before investing money and altering my car for competitve driving.
(Hint: it's cheaper to learn more skills .... at $40.00/per A-X; and a lot more fun in the driver's seat ....... than spending $$ and adjusting your car's street ride, only to get marginal improvements in your timed runs at the AX's. Improved skill level will improve your scores faster than car mod's at your current level of driving experience, in most cases.)
Kary's remarks are right on the money with this logic. I concur. Learn more, spend less, and have fun in the driver's seat. After a year of steady improvements in skills, look to altering your car.
As to camber, toe-in/toe-out, and other specs, talk to the pro's. They can help you gain the best setup configuration, at the best price, and find the best compromise between ride, speed, and learning. Kim's set up configuration sounds pretty good as a "bench-mark" for your set-up, but every car is slightly different. (
Bear in mind, with a more agressive set-up, your tires will tend to wear faster, so keep an eye on them. If you run negitive camber and don't do much tracking, the inside half of the tires will wear faster than the outsides. You'll need to 'flip" the tires on the rims annually to offset the wear-affect of negitive camber.)
As an example: my wife spent 3 years improving her skill-level in a 912 that was never "set up" for tracking in regard to the suspension or tires. She used to run 0.0-degrees camber, 1 to 3 mm toe-in front w/ 0.0 toe in/out rear, and street tires. She moved all the way up to 2nd place winnings in her class against other cars that may have had more set-up. Now, we've recently had her car completely set up (Happy Birthday, thanks Jae lee) with a more "agressive" track configuration. It will be interesting to see how she does.
Talk to others about this, but many folks think skill level will enhance overall results faster than spending lots 'o' cash up front.
These are just my opinions.
