The “winglets” could fit with some customized tab removal/dremel shaping and might hold with 3M tape, but screws would be the only way to solidly attach them. The R bumper also has an undermounted bumper support that prevents the winglets from getting scratched/ripped off by low curbs or other road pitfalls. I bought them from E-Acca (along with the R fog surrounds) trying to get away without buying the whole R front bumper but will probably end up going that route at some point. Not a huge fan personally of the EBay fog trims but I get the appeal.
I can appreciate this and while I ordered them ($50 why not) I have still not installed and they are certainly a massive compromise. Go Golf R front skin and supporting parts and don't look back.
For all; I put this list together a while back and quickly scrubbed ECS/VW/others for pricing. Pricing is probably dated and a rough estimate at this point. At least this is a solid parts list as a reference point.
