As a PSA - got a set of Pirelli PZ4 sport tires because they were extremely lightweight (21 pounds), and figured if they worked well with porsche, they would do decent with an M3P... Those tires have to be hot to get sticky, like asphalt well over 100 degrees and tires way above that kind of hot. Outside of that small operating environment, they are slick as sh1t. Tried running lower pressures that recommended just for launching, and nothing seemed to help, there was always enormous amounts of traction control nerfing the power output or wheel spin in track mode. Luckily discount tire was cool even though I put 2k miles on them and they are exchanging for a set of ps4s. Hate to add the extra weight back on the car, but if your ass end is sliding around on-ramps, don't really have much of a choice.
