Justin Marks reacts to Trackhouse Racing's brake rotor issues at Nashville

Sunday's NASCAR Cup Series race at Nashville Superspeedway produced an edge-of-your-seat thriller as Denny Hamlin rallied from a clear start violation for his second points-paying win of the 2026 season.

While the Joe Gibbs Racing veteran continued his consistent start to the season just outside the "Music City," one organization that left disappointed once again is Trackhouse Racing.

Sure, road course ace Shane van Gisbergen led 12 laps and scored a career-best oval finish of fifth as he continues to make noticeable improvements on those layouts. However, that does not take away from the issues that seem to plague rookie Connor Zilisch and Ross Chastain every week.

That carried over to Sunday's race as both drivers experienced brake rotor issues that ended their night prematurely in the first stage of the 300-lap race. Trackhouse Racing owner Justin Marks addressed that missed opportunity from Nashville during an appearance on SiriusXM NASCAR Radio.

"All indications are that the brakes got too hot into the corner and too cold at the end of the straightaway and those fluctuations in temperature sort of break down the structural strength of the rotors," Marks said. "... It's something that we're gonna have to really look at because we lost an opportunity (Sunday) night to really have a great showing for our company with the speed that we had in the race cars, the confidence that all three of our drivers had. I think we certainly had the opportunity to put all three cars in the top 10 and it just stings to miss that opportunity. We have to just make sure we do the work and, forensically looking at it, make sure that that doesn't happen again to us."
