but seriously guys im using the Azenis semi slick tyres on my gtr, and ive never had a better tyre then them, once they get warm, there isnt much differnce in the grip compared to all the other tyres mentioned, the only differnce is that they are east to drive with daily, not noisy, and handle very very well, mine dont last long only a couple of months, but thats only casue all 4 wheels spin in most gears once boost kicks in, ad its only about $1240 for the whole set of 4.
for street use i highly recomend them.
