It does, but very slightly... and by just bending the tabs that the fender liner attaches to up to maybe a 45 degree angle, you are still able to attach the fender liner, and no more rubbing.

 

any pics of this setup?

 

 

You said for The Track... and every little bit helps for maximum benefit

 

You dont think the 17x10 +50 all the way around will hit the front suspension arms?

 

No.

The 6ULR's from 949 Racing are available in 17x10 +52. Some people that ran those up front reported light contact with the suspension arms at full lock. This did not affect some others that were running the same wheels. So that leads me to believe that 17x10 +50 will clear perfectly. You will just have to roll your fenders more, but that's better than rubbing metal on metal.
I believe Evasive has CE28N's available in 17x10 +50 in stock. This is the route I would go if cost wasn't a factor.

 

Here's a fb link to the CE28N's in 17x10+50 on an S2k:

in addition to the arms, depending on how much you are lowered, they also hit the frame in the wheel well. +50 might give enough clearance, not sure.
