You wouldn't believe a little lug cap would make a huge difference to the overall look of a car tire until I fitted them to my 2005 Jaguar XK8 Convertible... but who cares what they did! This is one of the best $5 investments I've ever made in my Jag! They are aluminum, very well made and look amazing on my new powder coated wheels! The perfect ending! Beauty is in the small, tiny details, and the leaping Jaguar logo on the peak of each cap makes them stand out! I highly recommend!
