These quarter extensions are available in coupe or fastback. They feature mounting studs already installed and a return lip so that you can sand it down to the depth you need for a lot of adjustment. These are made to be used with our rear trunk spoiler or deck lid. Please do not interchange other companies deck lid with the quarter extensions or vice versa. Please watch the YouTube installation video for a full explanation of these extensions.
Note: Always make sure your deck lid with a weatherstrip is bolted on the car before fitting the extensions.
