Fast Lap With Billy Johnson :  Auto Club Speedway Roval (Video Inside)

By Billy Johnson

Auto Club Speedway, previously known as California Speedway is a relatively new track built in early 1997 and has been the host for many racing series including NASCAR, IRL, Motorcycle, Grand-Am, and even JGTC. This D-shaped oval incorporates 11-degree banking on the front straight with 14-degree banking in NASCAR Turns 1 and 2. This track also has a series of infield road-course combinations with the largest and fastest utilizing the oval’s front straight and first two turns before going back down into the infield. This 2.88 17-turn "roval" is a common configuration for everything from Grand-Am to track days.

The Buttonwillow Bible- Fast Lap (In Car Video inside!)

By Billy Johnson

Buttonwillow (BW) is a great test track used by many professional sports car and formula car racing teams because of the track’s variety of corners.  From on-camber and off-camber corners, to sweepers, chicanes, hairpins, and man-made elevation changes, BW is a well-balanced and technical  track that challenges both the driver and car.  In recent years BW has become center for Time Attack drivers and teams attracting cars from as far away as Japan. Like Tsukuba Circuit in Japan, Buttonwillow has become the milestone for lap times for the top tuners in the time attack world. It has also become the benchmark for bragging rights for many OEM manufacturers.
