I'm having a hard time looking for lowering kits/coilovers and body kits for my '05 Sebring 4dr Sedan so I joined this forum hoping to get some answers I really want to trick my car out.

 

You won't find much. There's not much of a market for accessories for a 14-year-old car that was pretty much a plain-vanilla family sedan to start with. Cars with more pizzazz like a Mustang still attract buyers with money to spend customizing and souping up their vehicles, and there are companies out there willing to invest in the tooling to produce parts for that market. Sebrings never pretended to be a performance car, few people ever considered trying to turn one into a performance car and custom shops do not see it as a way to make money. There might be some possibility of finding things for a Sebring coupe as it was a little more interesting vehicle to start with and shared a platform with a Dodge and a Mitsubishi vehicle of similar cachet, but if there exist such things, they won't transfer over to the sedan because it's a completely different vehicle.

If you find anything out there, let us know.
