I tend to think that a subtle drop with lowering springs is a far better option then going with bigger wheels. My 02S is on stock 17" twists and I think the sizing is bang on for the weight and power. Maybe I'll bump the fronts to 215s or 225s in an attempt to dial out some of the understeer, but that's it. I think 19's are too much wheel for the car. I'll never understand the benefit of ultra low profile tires for street use. I think it makes the car less usable, less tossable and in may cases slower off the line and out of turns. It will likely also cost a few MPGs. If you're pushing 400+ hp then by all means, go with some huge fender meat. Otherwise, I think it's kind of the automotive equivalent stuffing a sock down your pants. It might look mean and attract attention, but at the end of the day it's "false advertising" if it's only for looks. Which stands out even more on a Porsche, not a designer known for having unneeded bling.
Just my opinion! Good luck!!!
