We had the pleasure of hanging out at Hardway Performance this week! Ryan was kind enough to show us around the shop and show us some of the projects he’s working on! We were lucky enough to see Montana working on his truck getting ready for 72 fast! Can’t wait to see everyone out in Indy for Ultimate Callout Challenge
