My car puts down 320whp and 350wtq. I bought these for a summer set on my summer wheels. I do drive a little more agressive than majority of people and I can say these tires are amazing. Last year i had the Nitto NeoGens in the same size. Due to the price and reviews i decided on these. I can launch my FWD car like a dream in these, but they still allow or some tire smoke if needed. The side wall stiffness is good and turn in is precise with very good feel for the driver. They are not my autox tire set, but they will see the drag strip occassionally and I will update on treadwear and how the tires respond after a couple thousand miles on them. So far, awesome tire for the price.
