The F30 suffered similar poor braking reviews with low rolling resistance tires (and good reviews with performance summer tires). It seems that the Pirelli Cinturato P7 Summer and Bridgestone Potenza S001 perform much better (even though Pirelli advertises the P7 Summer as LRR). M sport owners with staggered setups should also benefit from more rubber in the back.
