Every WPM half cage is built for non-sunroof cars. Email your year, chassis, and options before you order and we will answer directly. Ask a fitment question.
We recommend welding the cage in. Bolt-in base plates are included as well; using them usually means drilling through the vehicle. Professional installation is heavily recommended.
Standard finish is satin black powdercoat. Custom is any color from Prismatic Powders. Select Custom, type the Prismatic code and color name on this product (for example, PSS-11632 Porsche Speed Yellow), then add to cart. Do not put the color on the order note. Standard and Custom are the same price.
Once it ships, transit is usually 3–5 days, subject to change. F80 and G80 cages ship US freight. Freight often lacks accurate tracking and may take longer than ground.
