who cares if people frown - its your car so do what you want to it.

Personally I would get a fibreglass rs500 upper spoiler instead as the lip will have a raised edge against the spoiler - not bad if you look from far but fairly noticeable if up close i guess. But they are a cheap mod.

If you have the orginal 3dr spoiler - sell that with the caps and that will pay for a fibreglass rs500 upper spoiler.
