Hey all,
I've been looking into running a square wheel/tire setup on my '99 Boxster for a number of reasons. I won't get into them all here.
My ideal size/setup, based upon my own preferences, would be 17x8 wheels all the way around running 235/45/17 or 225/45/17. This would be used solely for street use and daily driving.
I feel like most of the boxster/porsche community scoffs at running a non-staggered setup, or going down below 255 width in the rear. I haven't understood this, as the original 1997 boxster was running 205/55/16 and 225/50/16 tires and the weight and power didn't change for 3+ years and even then, barely changed.
So I've been doing some research and this is what I've found so far:
1. $900 will buy you 4 brand new/take-offs from a Cayman in 17x8
2. RUF Auto Centre built a spec boxster running a square setup of 17x8 (

3. I haven't found any owners reporting that a boxster running the original 16" tire sizes handled poorly, or wasn't perfectly suitable for aggressive day to day use.
Still doing some research, but I'm narrowing down on this setup as a great blend of ride quality, performance, and longevity of tires.
Just wanted to share this...
