This video was shared by 88dx on our forum and it features an LSX swapped Mazda RX-7 and a Kawasaki ZX-10 battling at Sandia Motorsports Park in New Mexico. It's definitely one of the more unique drifting videos I've seen. They even managed to use an RC car to capture some chase shots of the car and bike. The video was put together by ICON (a bike apparal manufacturer).
