Pilot Super Sport * (oem) vs S4 after market (non oem)
My M550 came with Pilot Super Sport * (oem), the fronts did not wear well and considering replacing with non oem S4's since there is no * spec for the sizes I need (245/35x20 & 275/30x20). Now after seeing how much different tech went into the BMW * spec S4's I wonder if anyone can comment on any differences related to the oem and after market version of the Super Sports.
