My last car didn’t have a spoiler so I always wanted one, I think the OEM coupe wings look pretty sweet honestly. But after I got my roof spoiler on, I started to dislike it more and more until I finally removed it (it and the roof spoiler together just started looking too “busy”). Now I have a trunk lip which is more subtle and better echoes the roof spoiler.
If you definitely want to go wingless, I would just keep your eye out for a wingless trunk, no matter how long it takes. Afterall it’s not like it’s something that absolutely has to get done. I couldn’t find a wingless trunk after looking for months, so I finally bought one that use to have a spoiler for $50 at a junk yard, had the holes welded shut and grinded down, then had it painted. When all was said and done, I spent $375. So if you’re not in a rush, I’d recommend taking your time, and just wait until you find a stock wingless trunk lid.
I do think the OEM wing looks good though, as long as you don't have a roof spoiler.
