I would prefer the most rubber with the largest brakes I could have on the wheels. If you can fit 18 inch wheels around the brakes get 18 inch wheels for the track. If you need larger get larger but only as large as you need to fit the brakes you need.

Choosing the right tire depends on the track conditions you will see. The better the surface, the less tire compliance is necessary. Within reason, all other things equal, having a lower profile tire will:
1) reduce unsprung mass (if one selects a proper forged wheel)
2) reduce tire temperature & pressure variation
3) improve cornering responsiveness
4) last longer
If you drive on a rougher road surface, then you need more sidewall to allow the tire to deform to the irregular surface. But why put on taller tires than one needs? IMHO, the only other reasons to stick with large profile tires is if you're on a budget or deathly afraid of curb rash. Neither should be the case if you're driving a Porsche.

I will say, you can definitely own a Porsche on a budget! I have two!

For a drivers car I would do the 19"ers as they are as good as any, esp with race rubber. And they work for resale as many summer, AS and winter choice tires are avialable. Im done with keys in and out all day - keyless is the way to go. Drivers dont like freezing or sweating so the heated and ventilated seats are a big plus. I like the PTV, AS and the hitch options. Serious drivers may need to haul some race rubber to the track (or bikes to the nearby trail). And unless I live way in the boonies, I want the Bose and HD radio options. A serious driver needs some serious motivation and it takes some good music for that to happen. the only frivolous option im going for is the colored wheel crests - they look great and are cheap. All these are good for resale. What more can I say?
