Just recently I was able to push them at an AutoX event and they held up beautifully. By this point they probably already had about 15,000 miles of driving on them (about one full year of ownership). The grip through slaloms and Chicago boxes kept the car planted and I was able to point the car in the direction I wanted it to go every time. I can probably get about one more event out of them before needing to be replaced assuming I get about 5-6 runs.

 I decided to give them a try on my daily, BMW 330i. I can say they have great grip in the dry and are really good in the wet. Large channels for water and lots of surface area still for good grip. They are also really quiet which for a daily is nice.

I've ran 123s, RE760s, and ATR sports and these 651s tires out preformed all of them by a long shot! The wet grip from these tires are far superior to the dry grip of any other tire. And the dry grip is unbelievable. I ran more pressure in the rear of these than any other tire I've ever used and still had far more grip. I was blown away! Thank you so much Tire Streets and Accelera for making my car a rocket ship!
