A-spec article in Motor Trend (scanned in article)
I know this is an old article but I scanned it in for all your viewing pleasure. Enjoy 
Oh sorry for the bad image. The article had some fading on it.

Why would the A-spec be .3 seconds faster 0-60. I would think larger wheels and more weight <<<body kit would slow it down if anything. Is it simply a case of traction w/ better tires? seems like the braking sure got a boost.

goes to show you how crappy the OEM tires are on this car... As for 18s well read up on them.. All depends on the wheel weight etc.
One thing about hooking up better is faster times.. the bad thing for you people who like more show than go, is you do not spin them as much

Well, wheel weight and also the moment of inertia of the wheel/tire assembly over all. While a tire might have less sidewall to produce the same overal height, the weight of the tire and the wheel need to be compared. If the wheel still weighs a significant amount compared to the tire, then you need to look at how the mass of the wheel moved outwards. For instance, lets say (exageration) that a 17inch wheel and 18inch wheel both weight 30lbs each, and the tires weight the same also. Even though a tire on the 18 inch wheel would compensate for the overall height, the fact that the 30lbs wheel weight is potentially spread out over a larger radius means a higher moment of inertia, so more power is required to get it going. All I am saying is wrt to wheels and tires a bit of mass properties analysis needs to be done...

The farther the weight is out from the center of wheel the harder it will be to spin. Ideally you would want most of the weight in the center of the rim. But then you would loose the strength of the rim on the outer part making the rim susceptible to bending. That would suck.

correct. So, mass properties, strength analysis, lots of things to consider. I was just pointing out it takes more than an overall diameter or weight to determine the performance ramifications (good or bad) of a wheel and/or tire. How that weight is spread out is critical.
