I'm running megan coilovers and the S5 T2 wheels I have with 225/50/16 tires. Currently I have about an inch of wheel gap and the T2 wheels were rubbing prob by 2mm.

If I run the 17 x 8.5 and 9.5 + 14mm offsets with 215/40/17 and the rears with 255/40/17 .. am I going to be good on clearance?

 

inner clearance = no prob

youre gonna have to roll fenders tho

 

i dont think the 215 is going to give you enouph bite. but post up some pics ofter you put them on and let us know what you came up with, iv been thinking of going with a wider 17" also
