What am I missing here? RealTimeRacing ITRs run on 17" wheels... They aren't slow.

Most 17" wheels weight significantly more than stock; even if they're lighter (like in my case) the larger rotational mass (of the wheel) = more torque required to turn the wheel, which equates to slower times. Tough to imagine how a 14.75 lb. wheel would slow me down as opposed to a 16+ lb stock wheel but it does

All things being equal, larger wheels & tires should have better handling because the tread width is increased.
However, assuming the engine has the same output and there are no suspension changes then the mass of the larger wheels and tires would result in slower acceleration due to the torque required to turn the rim mass that is further away from the wheel's centerline.
This help explains why drag wheels are only 13" in diameter but very wide.
The best compromise between performance and appearance would be with 16" wheels with 205/45/16 tires.
In general,
smaller wheel = faster acceleration + poorer cosmetics
larger wheel = better cosmetics + slower acceleration
BTW, I have stock 15" wheels upgraded with grippy tires.
