Took me going to 4 PEP Boys stores but I finally found 5 packs of the 4602 McGard lug nuts. No big deal as all of the store visits were incorporated into my travels during the week. I had painted my calipers and took off my wheels for the first time. I realized I wanted something more that the chrome lug nut covers that came with my Bonneville.
The cost at PEP Boys is $7.88 a pack of 4 so you will need 5 packs. Summit has them for $9.95 a pack. The good point is you only have one item to remove instead of the cap and a lug nut. The bad, for me , was my lug nut wrench would not work to tighten them up, not a deep enough recess, which is no big deal because I used a deep well socket and a torque wrench to install them.
I think the visual gain is minimal and will only be noticed by you. It boils down to was it worth the $42.00, includes tax, to replace? Over time I believe it is due to the less hassle when rotating tires and the possibility of lost lug nut caps.
Here are the pictures enjoy.
