I believe the bumper bar is black so you should be good.I may also get some plastic to block some of the new vent out so you're unable to see the rear bumper support.
I wouldn’t recommend doing this because it wouldn’t match the front vents.What would these rear faux vents look like colour matched ? Too weird?
Ha! Originally I thought you meant after the conversion. IMO just painting faux vent would look weird. Some people dislike all the black on the bumper. Doing conversion there’s opportunity to reduce black. Cutting out entire vent hole and re-spray the trim color of car. But then I would paint vent trim in front to have unified look.What would these rear faux vents look like colour matched ? Too weird?
Hey Bud, how’s the DIY going?
Update?
I totally agree and something I was strongly considering. I think either black or color match trim and keep mesh black are best options.I wonder what it would look like color matched on the outside trim but keeping the inside mesh black. I think it would do a good job of making the vents appear smaller but still looking factory.
Interested to see if it has any ill-effects on aero. Try to do some testing for mpg and report back please.
