Honestly I was at 16K before I switched to my current set of Bridgestone RE-11s. However, I bought the car with almost 4000 miles on the clock, but I'm pretty sure they were the original PS2s. In that 16K , I participated in three track days if I remember correctly.

2008 AW/Blk 6MT, Akrapovic Evolution, Evosport Pulley, ESS Tune, Michelin PSS/Hoosier, other track stuff SOLD
