I upgraded to the premium center caps for my recent purchase of RT109 and am very pleased with them. While the center cap is certainly not the focal point of a wheel it can greatly change the overall vibe of the wheel. In my case I felt the new premium center caps gave a stronger offroad appeal whereas the old center caps were more appropriate for a wheel on an old school muscle car. The new caps are lower profile, fit snugly with no slop, and look excellent. The ridges on the edge and raised logo provide a rugged look and the chrome color logo matches great with the chrome nuts on the faux beadlock rim. They complement the styling of my RT109 much better and I am happy I upgraded. Although the cost is not significant, I do feel these should be made standard instead of an additional cost especially if purchasing a set of wheels since their introduction.
