IMSA: Roar BoP tables revised


IMSA has made an interesting revision to the Balance of Performance tables it will use during this week’s Roar Before the 24 test at Daytona International Speedway.

In the Prototype class, where spec World Endurance Championship LMP2s and LMP2-based Daytona Prototype internationals coexist, the BoP table released on Dec. 30 allowed a degree of aerodynamic balancing between the WEC P2s. Under the Dec. 30 BoP, numerous options – mostly downforce- and drag-reducing measures at the rear of the cars to achieve the high tops speeds needed to be successful at Daytona – were listed as permissible for the Roar.

In today’s revision, the Daytona-specific WEC P2 aero balancing has been removed.

It means the Gibson-powered WEC P2 cars from Ligier, ORECA and Riley/Multimatic will only be allowed to use the aerodynamic packages homologated by the FIA for use in the WEC (and in IMSA).

An update to the GT Le Mans BoP for the new mid-engine Porsche 911 RSR was made to the minimum rear wing angle for the Roar. Previous listed as TBD, IMSA has given the Porsche GT Team’s cars a minimum angle of zero degrees to use during the Jan. 6-8 test.

No changes were made to PC or GT Daytona.
