The R1 Concepts Geo-Carbon drilled-and-slotted rotor for the rear left of 2011–2016 BMW Z4 is made to fit that specific rear-left position. The drilled and slotted face plus Geo-Carbon construction support heat dissipation and removal of pad deposits, helping maintain consistent braking under regular driving demands. Fitment is taken directly from the explicit product listing.
