I’m wanting to get black wheel nuts, do you know the best option for my wheels then?

I installed it 7 months ago:

The All in One Lug nuts for the FoRS thread

For anyone considering the blue Muteki SR48 open ended lugs, here are some installed pics. Pretty subtle but I like the look.

Driven Products are quite affordable and I haven't had any wear and tear or chipping from multiple removals (including the apes at ford using air impact tools).

 

I'm getting these today, will report back once I have them on. They are the standard 19mm socket (but the listing doesn't that that anywhere for some reason)

I have these black McGards on now -

I was so impressed with these that I bought a set for my F150. Unfortunately Amazon/McGard sent the wrong ones so I contacted customer service and they immediately replaced them no questions asked. They didn't even want the incorrect ones back...!

 

I have these as well and have been super pleased with them. No complaints.

 

I have those McGard's but I just switched to these Gorillas:

Gorilla Automotive 71633NBC Gorilla Wheel Lock Systems | Summit Racing

 

My reason for change is not so much the fit but the style, I was tired of using 1 locking lug which was an eye sore. I like symmetry and those Gorilla's offer a somewhat locking feature while being symmetrical.

 

I went with these. Car is garaged and I rarely park it anywhere for too long to worry about someone messing with it. Also bought the Lug wrench with them. That thing is really handy. No more knuckles getting busted.

I like them cause you can start them all the way snug with our fingers for the most part
