Only problem with ARS is that after 5 years the hydraulic tensioner tends to leak and eventually need to be replaced. I plan to eventually remove them and install a heavy fixed sway bar, like H&R.
I already have a small leak but living with it for now.
Agree that F10 steering is awful. Makes it feel like a Buick.
