Just 'joined' this club today. I got the Rial Le Mans from Tirerack, 15x6 all around.
Wrapped in 195-50-15 Yoko S Drive.
I tested lock-to-lock tonight and got NO rubbing with the 15x6 wheels/tires up front. The wheels/tires now come out to be flush with the front fenders now, rears look to be a smiggen more flush as well.
I went this route since I was sick and tired of the staggered set-up inducing more understeer than the suspension already did. Time will tell if this helps with that or not. But it should also help with highway manners and aggressive turn-in as well. Added bonus of being able to rotate them front-to-rear (due to directional tires) if I want/need to.
