Bought it over the winter, but as the car was in storage, it was recently painted and fitted. I went with S2000 front brackets and their upgraded rear brackets, which allow for an elongated nut to clamp it down. It was watertight but initially creaky from the rear. Found this video on YT and tried the suggestion which is a length of weatherstripping along the rear deck. It worked great.
