I have a 2013 Impala LTZ And I‘m looking to lower the car while getting performance out of it aswell. I‘m not the type of car expert here so I‘m asking everyone on Yahoo lol.
My suggestion would be to use air adjustable coilover springs and shocks. You can set the ride height and the car will handle better. Impala isn't exactly a sports car you know. So not sure why you would want to put a bunch of money in suspension. If you want to spend the money heavier sway bars will control roll, slotted and drilled rotors with larger calipers and racing pads like those made by Bimbo will let you stop faster and reduce or eliminate fade depending on what you buy. But you could drop 8 to 10 grand on a suspension if you want to easy.
