Well okay then... :p
Personally I can't get any traction with 215/50's so with 215/40's I would be much slower... The stock KDW's have very little rollover (when pumped up) so I can't see 40's making a huge improvement here, but???
I'm actually looking forward to 225/50's for the slight lowering of the final drive ratio. That on top of gaining an extra 1/2 inch in width should really improve my acceleration and handling.
