Bdc101, I would say yes. I don' have a heavy foot. At normal driving, the X5 walks away from city traffic light to light. The entire suspension refreshed and driveline giubo/carrier bearing all made a difference. Steering feels slightly lighter. We know X5s have heavy steering. Better power going to the front wheels does feel better. 255/60/17 tires feel better than stock 235s.
