The 4.10s are sick. Not sure how well the 3.73s turn the tires but I am spinning my 315s on a 40 miles per hour roll with my 4.10s. Congrats on the 3.73s...let them break in before you run them too hard. 500 miles is a good number. Yes, I am aware some people get them and run them right away, but then again, some people sniff paint. Sure it is fun and all, but the long term damage just doesn't make it worth it!
