Performance wise, the smallest wheel you can fit while still clearing the brake calipers will be the 'best' because it'll always be lighter than the exact same wheel in a larger size.
Assuming you are running dedicated track tires, they should be light and have minimal sidewall flex so there is no reason to run a larger diameter wheel.
Most guys who track their cars have 18's or smaller. 19 and 20 inch wheels are usually just for show.
Of course if you can afford 2000$ per wheel, you can get super light forged 19's that are both light and sexy...
