At the moment there only seems to be the more expensive option of the dealer installed door sill trim. I contacted a custom fabricator who makes door sills, and many other quality products for Hondas and a few other Japanese brands. If any California owners are willing to give an hr or two of their time at their shop so they can perform some test fitments and take dimensions I'm sure they can come up with a quality product. I do not want to violate any forum rules by giving out the shop's info as this may constitute advertising. If you pm I can get you the contact info and website so that you can look at the products yourselves
