1964 Chevy Chevelle Sway Bar Tests - The Great Sway Bar Debate

We Test Five Different Sway Bars In One Day And The Results May Surprise You.

Hey Doug, What's Negative Roll?
"Negative roll is something we came up with in 1984. It is a combination of components that make up the geometry. Negative roll refers to the camber gain as the tire goes up into the fender. Negative camber leans the top of the tire in toward the engine. Positive camber is when the top of the tire leans out toward the fender. The factory geometry uses positive camber gain so that when the car goes through a turn and the tire goes up into the fender, positive camber kicks in and your handling is reduced. By going to a negative roll system, which are taller spindles and a special length upper control arm. Negative camber can be induced through the turns. The tire leans in toward the engine providing more footprint on the pavement, increasing the cornering ability of the car." -Doug Norrdin

Ed's Driving Impression
Before leaving the track, Norrdin recommended we install the hollow front bar and remove the rear bars for the best on-the-road setup. We asked Zinke the next day how the car felt on the drive home and here is what he had to say. "The hollow sway bar improved cornering significantly without affecting overall ride quality. Normal ride remained almost identical to stock bar with only a hint of being more rigid. It's a very subtle change that is comfortable with no harshness at all. In cornering, body roll disappeared and remained flat with improved entrance and exit speed throughout. The final combination greatly improved driveability and enjoyment." -Ed Zinke
