Well, the 4.10's are in, and I feel like a kid in a candy store. It feels like a new car. Simply amazing. I'm glad I didn't go with 3.73's, I don't think the difference would have been as noticable and I would have regretted that choice. I was worried that I would get a set of FRPP's that are now made by Motive, but no worries, I have the American made. There's goes my gas mileage for awhile while I get over the desire to constantly play with them.
