A straight piece of tubing is a lot stronger than one that is bent, even if the work has been done on a mandrel bender. Although lots of bends are necessary on a racing chassis, Leavitt says he tries to keep as many straight pieces of tubing as is possible. As an example, he points to the downward sloping bar on this truck chassis. Racers must put a piece of Lexan between the bottom of this bar and the top of the truck bed, called the "Romeo Window." On the right side, this window can keep the air from hitting the spoiler, so Leavitt must bend the tube to minimize the area. This isn't as big a deal on the left side, however, so he's able to leave it straight.
