No regrets here, and not one problem as a result of the rims. I have the 8 cylinder and love to use it every once-in-a-while, but if I was concerned about get up and go I would have bought a sports car, not a four door family sedan.
The car can still get out of its own way just fine. The added rotational mass and weight of the wheels has caused little difference in acceleration and braking for the type of driving that I do. I would never say that everything has remained as is since adding the larger wheels, but definitely hasn't changed the ride so significantly that it's caused me to worry.
The only regret I felt myself having was when I mounted up 20's to see if I would be pleased. The car gobbled them up like they did the stock wheels. I couldn't help but go with the 22's.
