Basically the same as my observations after changing to the MXM4s on stock wheels about 6,000 miles ago. Unfortunately, I can't say it helped the steering feel much; alas, nothing is going to make it through that wall of over-boost!

Efficiency appeared to be a little less initially but after 1000 miles, it's about the same compared to stock wheels and tires.
