A RWD car with IRS and good suspension geometry will almost without exception end up with more front than rear camber when properly tuned. So expect to end up that way after experimenting.
There is no "right" answer or "perfect" alignment for every condition though. Just compromises. When it's dialed well the compromises are very small and you get the end result you want.
You need a lap timer, fast and consistent driver, pyrometer. If you have alignment tools you can bring to the track, that's a bonus but you can learn a lot without changing alignment at the track.

S2k setups are usually more rear camber, but in many cases that's due to more rear camber being available, and also to the early S2k's rear roll stiffness bias. RWD production cars almost always run more rear camber for a safer more understeering handling demeanor, but more front camber is the norm for decent power/weight rwd track cars.
What's best on your particular car depends on the overall setup. Personally, I'd go for more front camber (~3 front, ~2.5 rear) and stiffer front vs. rear roll stiffness to balance.
As for pyrometer testing, be aware that even temps across the tread is not necessarily the ideal. The stopwatch is the ultimate measure of what's really optimal. Faster setups will often run hotter temps at the inside of the tread. This is partially because at higher speed straightaways, you're heating the inside tread more than you'll heat the outside during cornering.

Normally a 20*F spread (with the inside being hotter and the middle of the tire in between outside and inside temps) is preferred.

Its good or not ?:-)
Too many other variables between cars and drivers and tracks and tires.... What is good for me may not be good for you. What is good for you may not be good for me.
