I got a bit more balls after driving for some time and I am now running something like 57 pounds in front and 80 pounds in the back. (car has mad reverse rack if I have anything less then that in the back so dont ask why I run so much in the rear) and I get the feel like somthing started self-notching cuz discomforting sounds reduced since last weekend. Trip to montreal has something to do with it I guess, but I will see the real cause this saturday when car is in the air.
