Welcome to our show Unsealed: Life Beyond the Bolts! Each week, Kate Dillon from Crate Insider and Steve Hendren from Hendren Racing Engines go live on the Crate Insider Facebook page to chat about world events, random things, and to answer tech questions.
This week has been busy for Kate and Steve. Kate has been preparing for Bristol, complete with a freshly wrapped van (done by Dirt Wrap). Steve has been working hard to get engines rebuilt for his awesome Hendren Racing Engines customers and keeping up with random holidays.
