Pilot Sport 4s are in the country and are being fitted as we speak. I have installed them (225/45R17) 94Y for $185 a corner and just this past weekend I ran them for over 1300km (Sydney -> Parkes -> Sydney) over some seriously rough roads and more than 40km of graded gravel roads.
It was wet, it was dusty and it was high G cornering.
Coming from Pilot Super Sports they have a very similar square wall stance (PS3 do not have a square wall)
They were quiet. They gripped. They're good.
