I'm running 205/50-16 Neo Gens on 16x8 Dekas, 40ET, and there is some rubbing on the front during braking, and on low speed, sharp turns (i.e.; like pulling into a parking spot) while braking, on the FACTORY suspension.
The Nittos seem to run VERY wide in section width for this size though, so it may be tire specific, but, I DO wish that there was less 'poke' from this setup (like a 43-44ET or so on the wheels would do), especially in the back, where it looks 'goofy' at factory ride height.
