As the title says. I'm curious if there is anything that I can do performance wise to my Sebring other than cosmetic mods.
i.e. Cold Air Intake, coilovers?

 

The Sebring is a more or less plain vanilla vehicle. There just aren't a lot of mods on the market. There used to be "cold air intakes" that drew air from right behind the radiator and probably didn't function as well as the OEM version. They may still be out there but don't expect much by way of performance improvements from them. Same story with suspension components. If you had a Mustang, you could find tons of mods on the market. Sebrings, not so much.
