The Penta-Carbon™ is designed to be customized to your specifications. The heart of this customization is a beautiful five-sided carbon fiber endcap produced exclusively for Brock’s Performance by world-renowned carbon composite specialists Blackstone Tek. Not only is the carbon cap available in gloss or matte finishes, we have also expanded the offerings to match any available BST carbon fiber wheel custom ink colors, for a combination that is truly unique.
