You'll find that there are highly polarized views on the topic. However, few will argue that the common goal is to reduce unsprung weight and rotational while not compromising strength and reliability . Personally, I run 19's on my vehicle. And, for the reasons previously mentioned, I am very pleased with how they perform over the oem 18's . That's not to say that I couldn't have accomplished the same with 18's, however, the set that I have now met all of the criteria .

Thanks Johnny - and I agree - but then 17's would be even lighter. Is there any consensus on the best performance combination for tire/wheel size?

The fastest Boxsters on the west coast are on 17s. The new lightweight Boxster Spider 19s are pretty good and comparable in performance but the tires are 2X the price of the same width in 17 inch and selection of quality 19" tires is still limited. Those drivers that shred a lot of race rubber run 17s for that reason.

Certain that it is , 17's are far more appropriate for track use than 19's . There's simply not enough rubber to run 19's under those conditions . However, for street "tuning" there's a practical application for running lighter, larger diameter wheels .

+ 1, 17's faster on the track, I use 17's on the track and 18's for the street.

I have Einkei NT03's and the 18's are 19 and 21lbs I believe. Not the absolute lightest but great for the price.
My BBS 3-piece 17x10's are lighter though...  Those don't fit the Box unfortunately.

Not necessarily, as far as I know my aftermarket 19's are lighter than any oem 17's .

Really? My 17s are 19lbs -F and 21.5-R. I have seen some exotic high $$$ 19 wheels that were lighter but it is rare. I have also seen some 35lb 19" replicas  .
