I love them. I have them in all three of my cars. All have factory 15" wheels and 235/70/15 tires. One is MP 360, one is factory E58 360 and one is factory 318-4. They are perfect for me for mixed driving. I had 3.21 in another old police car that I also had a MP 360 and 727 trans and there were annoying after any more than about 15 minutes at highway speed.
