The second round of the Global Time Attack series Pro-Am will be held at the Auto Club Speedway, August 6. 

For more information on the series, head to their website here. 

The Global Time Attack (GTA) series is one of the largest and most intense time attack championships in the world and attracts massive competitor numbers at each round.

Based in the United States of America, you'll not only see a wide range of the usual Japanese vehicles, you'll see some locally-produced American muscle thrown into the mix too.  

GTA is broken up into two main categories, Pro, and Pro Amateur.
