Not really, T4R's from the factory with a spoiler have a spot for third brake light that you can see but it is not open. You would have to have it cut out to accommodate the third brake light. The other thing to is you would have to get the wholes from the mount bolts for the spoiler filled, primed, and painted.
Personally, I like the spoilers on the T4R's. I don't have one currently but I'll be getting one. They look to plan to me without one.
