It was the second event weekend in the Radical Cup North America program, and a test day kicked off the weekend on Thursday as NTT IndyCar Series teams set up their paddock.
With large grids at the first Radical Cup North America event of the season at the Sebring International Raceway, the trend is continuing this coming weekend at Barber Motorsports Park with 37 drivers currently registered and confirmed to race alongside the NTT IndyCar Series.
