In the past I used to participate in the BMW drivers schools but have not for 5 years. My son and daughter are now driving and I was woundering what the latest opinions are on track/street pads. I am still running Hawk pads in the 88M5. I have run performance friction Z rated but think pedal effort is high. I have also run PBR metal masters. I have a set of Willwood polymatrix pads but the web information indicates these are really track only. What do the driving school people think. Thank you
