What size track wheels?
 

I am starting to get my parts put together for the winter overhaul and I was wondering what the opinions are on track wheel size. I have a 99 Box and will be doing installing PSS9's, gt3 front bar and h&r rear bar. I will be going to R tires for next year and am gathering info on whether I should be using 17's or 18's. I just sold my Classic I 17's because they got too dirty with the Hawk pads. Along with a few dollars I did get 18 x 9 twist wheels for the rear, so I am a bit committed to the 18" package, but I am looking for opinions. Take care, Bill, Pgh, Pa.

I would recommend using the square setup like with they use in Spec Boxster, I run a 17x8.5 square setup (same size wheels and tires in front and rear)with 255 tires, this allows you to rotate your tires and prolong the tire life, cause tires ain't cheap.
