***Mazda Team Joest returned to full strength in Friday’s afternoon practice session after the No. 55 Mazda RT24-P missed the morning session due to a turbo change. A team representative told Sportscar365 that the intake ingested debris, which led to the change.

***The No. 44 Magnus Racing Audi R8 LMS was forced to sit out the first 15 minutes of opening practice as a penalty for the team failing to submit its pre-event sensor declarations by the deadline.

***Action Express Racing team manager Gary Nelson said the reasoning for hiring Pipo Derani for 2019 was quite simple. “He outran us so much, we figured it’d be easier to have him on our team!” he told Sportscar365.

***Nelson said they are “very close” to securing the third driver in the No. 5 Cadillac DPi-V.R for the Michelin Endurance Cup races, with Gabby Chaves a ‘definite possibility’. Chaves is set to complete the team’s lineup for next month’s season-ending Motul Petit Le Mans.

“We’re going to test more with him in the coming weeks and race with him at Road Atlanta,” Nelson said. “There’s a lot of value to equity in our program; somebody we’re familiar with. We don’t like starting over. We think that’s a very good possibility but we’ll see how it goes.”

***Nelson downplayed the prospects of a fourth driver for the No. 31 car for the Rolex 24 at Daytona, admitting they are not actively searching at this time.

***It’s understood the winner of the Sunoco Whelen Challenge will likely be placed with a GT Daytona team at Daytona next year, ending a four-year run with Action Express.

***As many as seven Cadillac DPis will be on the grid next year, should a program materialize for Spirit of Daytona Racing and Wayne Taylor Racing renew its contract with GM.

***Cadillac pooled its resources in Michelin’s ‘On Track Opportunity’ at Daytona late last month, which saw Jordan Taylor turn laps in Spirit of Daytona Racing’s Cadillac DPi.V-R that featured engineering support from all three of its current DPi teams.

***A fifth and final scheduled Michelin on-track opportunity is scheduled for the Monday following the Motul Petit Le Mans and will be open to one car per team, instead of the previous one car per manufacturer that has been the case so far.

***Sportscar365 understands that Risi Competizione is likely to return for next month’s season-ending Motul Petit Le Mans, with Toni Vilander and Miguel Molina tipped to drive the Ferrari 488 GTE car.

***Alexander Sims’ future in the WeatherTech Championship remains unclear, amid his likely appointment as a BMW Andretti driver in the ABB FIA Formula E Championship, revealed by e-racing365 on Friday.
