I searched high and low for an "RS style" rear spoiler that would fit my 2018 Camaro SS. The RK Sport fiberglass spoiler looked perfect for my needs so I purchased it, only to have my body shop inform me that it is a very poor quality product. The spoiler is advertised as primed and ready for paint but it is far from that, what with numerous significant chips, dings, and very inconsistent body lines molded into it. The body shop also informed me that the fit of the spoiler to the trunk lid is poor with many inconsistent gaps. They told me it would cost at least an additional $500.00 to "make it right". I am not a big fan of the factory SS wing but the RK Sport spoiler is so bad I ended up putting the SS wing back on and will be returning the spoiler for a refund.
