Overview
- The NASCAR Cup race at World Wide Technology Raceway, which ran Sunday, spiraled into chaos with a track-record 18 cautions, two red flags and a double-overtime finish.
- Multiple catastrophic right-front brake-rotor failures caused major crashes and DNFs for drivers including Ryan Blaney, Chase Elliott and Chris Buescher and triggered several late cautions.
- Teams and drivers publicly disagreed over blame with some blaming the higher-horsepower, reduced-downforce package and track demands while others pointed to team setup choices such as nose tape and brake cooling decisions.
- Kyle Larson won the wreck-filled event to snap a 51-race drought and moved to second in the Chase standings while five title contenders failed to finish or lost significant ground.
- Calls for fixes range from manufacturer-NASCAR collaboration on brake components to Kevin Harvick’s proposal to allow post-practice replacement of pads and rotors, but NASCAR has not announced any immediate rule changes.
