Square Wheel Setup
I am thinking about running a square setup to alleviate some of the under steering of the car. Just wondering if some has tried that on their 3IS?

I'm running 18x10 +39 all around. its a bit aggressive for the front, i had to run a 5mm spacer to clear the knuckle... =/ but other than that its good. It definitely got rid of the understeer. 
I'm able to go into a corner with much more speed and control. hindsight...i would've gone 9.5 max all around just so i could clear the front with no spacer. and i rub a little on the fender lining in the rear on dips. good luck!

Stock wheels are 18x8 in front and 18x8.5 in the rear. I was thinking of buying two 18x8.5" OEM wheels from Sewell and running 255-35-18 x 4 (with Michelin Pilot Super Sports). 19" wheels/tires all around would probably be better, but if I go plus one I have concerns about diminishing ride quality.

Thank you so much for the inputs guys! Here in metro Toronto we do get some snow but the streets are pretty well plowed, so I have been running UHP/HP all seasons for quite a few years now. I am not sure if running four 255's would be good in the winter since they are pretty wide. Or would I be better off with 18x8 with 225 maybe 235 rubbers all around?
