Hi
Here is a closeup of my 300C with TSW Montage (5x114,3 hub -centric wheels) and 40 mm lower KW spring set. No rubbing or any other problems. Tires are Dunlop 265/35. Looks a bit different???
P.S. as I wrote before; if you use 5x114,3 bolt pattern, the centering ring must be made of metal and the fitting tight. Otherwise you will have vibration problems. If you dont want to try, just buy 5x115 wheels.
