Whats up with performance wheels?

[edevlin]

I have been reading about suspension upgrades lately, but I dont feel comfortable with doing the work, and I am not sure what is the most cost effective way to tighten the car up. So I have been thinking about wheels for my 2000 Boxster which currently has factory 17" wheels.

I tend to like the 17" because tires are cheaper, but if I saw a good deal on ebay for some 18" wheels with tires, I may go for it. My question is there a performance advantage to getting aftermarket wheels.

Are they lighter?
Are they stiffer?
Do they have less rotating mass?
Do they offer a performance advantage or just look cool (to some)?
Whats up with the multipiece wheels with all the bolts?


I will probably not track the car, but I sure like to go fast on the twisties, thanks.
