What you do first when you buy the M3 in winter and thanks to PYspeed !
as you might know I recently sold my e93 335i and bought my e93 M3.
Winter can be pretty harsh here and I had to rush for a winter wheel & tire setup. At the end I decided to go staggered 8.5 x 18 ET 35 (plus 12mm spacers) front and 9.5 x 16 ET 22 rear. The tires are 235/40-18 front and 255/40-18 rear. This is not an aggressive setup but it fits to the car pretty good, IMO. Tires don't look stretched at all.
I ordered the wheels from Eric and 5 business days later they arrived. As you see on the picture the wheels and tires are really needed.
Now, normally this post should be in the wheels and tires section, however, I did not find something comparable ( the wheels are V710's ) and I am very happy to have them on the car already, so I just want to let you know.
Again, thanks to Eric @ PYspeed, he covered my issues very well and provided excellent service.
Let me know how you like the setup. Sorry for the bad quality picture, it has been pretty dark outside.
