Drawing firm conclusions from the Roar Before the Rolex 24 at Daytona always is a dicey proposition. With IMSA officials keeping a watchful eye on manufacturer disparities, teams also are mindful about showing their hand.

Super cars took to the track at the Daytona International Speedway on Saturday morning in preparation for racing in the Rolex 24 next weekend.

The final day of IMSA testing during the Roar Before the Rolex 24 at Daytona International Speedway will be impacted by rain.

BMW ended up fastest and topped the times in three sessions over the official Roar test ahead of this weekend’s Daytona 24 Hours IMSA SportsCar Championship season-opener. A 1m35.424s around the Daytona International Speedway from Dries Vanthoor on the opening day aboard the #24 Rahal BMW M Hybrid V8 LMDh stood as the best time of the three-day test in which GTP class machinery took to the track in six sessions.
