IMSA’s TUDOR United SportsCar Championship and Continental Tire Sports Car Challenge are back in action this week, with a two-day test Feb. 20 and 21 at Sebring International Raceway. Several staffing changes have taken place since the week at Daytona ended in January. Additionally, there have been a couple Balance of Performance changes.
A quick recap:
- The full breakdown of BoP adjustments is linked here (P classes, GT classes), but there’s been several changes for the GT classes. The GT Le Mans-spec BMW Z4 and SRT Viper GTS-R each gain 15 kg while the Aston Martin Vantage sheds 20. The Aston has also been granted a 0.3mm restrictor increase; SRT’s restrictor has gone down by that much. In GT Daytona, both of the Daytona pace-setting Ferrari 458 and Audi R8 cars have received changes. Both gain 20 kg while the Ferrari has a 5mm restrictor decrease; Audi’s is 2mm. P class adjustments will likely be finalized after this week’s test.
- As far as the TUDOR Championship 42-car entry list goes, no major surprises. Starworks Motorsport’s P class car is entered, still with the same Dinan-powered Riley it ran at Daytona. Team Falken Tire is expected to make its debut with its new 991-spec Porsche 911 RSR; the team missed Daytona. In GTD, Rum Bum Racing appears to have partnered with Snow Racing, and the team shifts to No. 13 from 58 for Jan Heylen and Madison Snow. Matt Plumb is listed as third driver; Snow needed a third for Sebring as Marco Seefried will join Magnus Racing at the 12-hour race in March.
- There’s just 29 cars on the CTSC entry list. Notable here is the Fall-Line BMW team, which originally finished 2-3-4 in Daytona but had one car penalized (No. 47) and the other two promoted to first and second after the winning BMW failed post-race technical inspection. Only Rod Randall and Ken Wilden are listed in Fall-Line’s three M3s; the Daytona lineups of Shelby Blackstock/Ashley Freiberg and John Edwards/Trent Hindman aren’t for now. The 11-car ST class includes five BMWs, three Honda Civic Sis, a pair of Hyundai Genesis and an Aston Martin Vantage.
- OAK Racing, too, has confirmed its driver lineup for the rest of the TUDOR Championship season. Olivier Pla (5 races), Alex Brundle (5) and Ho-Pin Tung (3) will rotate at various times alongside the team’s lone full-season driver, Gustavo Yacaman, in the No. 42 Morgan Nissan.
The two-day test at Sebring sees the TUDOR Championship on-track both days from 9:30 a.m. to noon, and 2:45 to 5 p.m. ET. CTSC will be on-track both days from 8 to 9:15, and 1 to 2:30 p.m. ET. Live timing will be available on the IMSA website.
