OK, I've got my IQ with TRD springs and I have put on my Kyowa 18" wheels with Falken 225/40/18 tires. It looks great. Now, I'm thinking about some of those anodized lug nuts. Is there any problem putting aluminum lugs on a steel wheel bolt? Do these lug nuts require more maintenance than a steel one? I know they look cool, I just want to know if there is so much maintenance involved, it's not worth it. Any help would be appreciated.
