Sway bars on a V6 RS
I'm wanting to lower my RS an inch to clean up the lines and lower my center of gravity, but I'm curious about changing out the stock sway bars. I'm by no means an aggressive driver and tend to drive for fuel economy (hence the V6). I do plan on some horsepower gains in the future only because it's impossible for me to keep things stock. At what horsepower level would changing out your sway bars be recommended and what benefits have you all seen from changing them?
