E30 Door Seals
It is more than likely your E30 door seals are passed their prime. Over the years they become brittle and old, and even torn. When this happens you can not only get excessive wind noise inside the cabin, but it can allow water to seep in, causing your door jams to rust. CAtuned is now offering brand new door seals for either the coupe, sedan, or touring.
