Hey everyone, I have been getting emails if I will produce the ducted spoilers again. Unfortunately, back when I had ducted versions most people wanted a non ducted spoiler like the one mounted on my car so I changed the mold permanently to have no ducts. That being said the current spoilers still have the duct impressions on the back side that you can cut out and rivet or glue a flanged brake duct to. I have included pics to show you what I'm talking about. you can faintly see the oval shape but it is still there Front
the dimensions are 9.5 x 5.6 x 4.8 inches which fits on the back side of my spoiler.
If I were to do it, I would cut out the duct shape and mount this flanged brake duct either with rivets or ABS glue. That should make a solid duct and would be even easier to connect brake duct hose to than even the older ducted spoiler versions
