I want to do an event on Nov 13th. I plan on putting these on the stock wheels and then switching them for street tires after the race. The widest the ET streets come is a 275. With the Nittos I can get a 315. The Nittos look like they would last alot longer as they have a 6/32 tread depth vs the 2/32 of the Mickey Thompsons. Price is within a few $ so its negligable. I plan to launch the car semi-hard, but I don't want to snap an axle. What do you guys think?
