Twenty nine of the 34 cars entered for next month’s 1000 Miles of Sebring are also slated to take part in the FIA World Endurance Championship’s collective test session on the weekend prior to the sixth round of the 2018-19 season.

The WEC released the entry list for the optional two-day test on Thursday, featuring all cars except for the two DragonSpeed entries, pair of Jackie Chan DC Racing Oreca 07 Gibsons and GTE-Pro class Corvette C7.R.

DragonSpeed, DC Racing, Ford Chip Ganassi Racing and Toyota Gazoo Racing all took part in a private test earlier this month, in what marked the first laps for the Toyota TS050 Hybrid on the historic airfield circuit.

The majority of the drivers listed for the March 15 enduro will turn laps on the March 9-10 test, although BMW factory driver John Edwards has been added to BMW Team MTEK’s lineup for the test session only.

Edwards, who is not expected to be part of MTEK’s race lineup, has been recruited to help provide knowledge of the 3.7-mile circuit to the German squad, which makes its U.S. debut.
