Denny Hamlin has explained the reasons behind NASCAR teams rejecting the proposal for a “Run What You Brung” package at the upcoming All-Star Race at North Wilkesboro Speedway. Despite calls from insiders, such as The Athletic NASCAR reporter Jeff Gluck, for teams to approve the proposal, Hamlin has shed light on the practical challenges of the situation. During the Actions Detrimental podcast, Hamlin expressed concerns about the costs involved in modifying cars for the event and the financial implications for teams. He highlighted the significant expenses and logistical issues that would arise from building and racing these custom cars, emphasizing the financial burden it would place on teams in an already costly sport. Hamlin stressed the importance of financial sustainability for NASCAR teams and the need to address these challenges before committing to such initiatives.
