Pedders believes that Sway Bars are the final tuning element for any vehicle. The better balanced, sprung, damped and bushed the more benefits will be derived from larger adjustable bars. Many in the suspension industry believe that sway bars are the first step in improving an OEM suspension. They are wrong. The GTO requires sub-frame bushes, radius rod bushes, castor adjustment, rear coils higher in rate, nitrogen charged struts and higher critical damping rates at all four wheels BEFORE sway bars. Installing any brand aftermarket sway bars on a GTO before these foundational components are addressed is like putting lipstick on a pig.
While we are on the subject of sway bars, we should talk about the Rube Goldberg designed GTO front sway bar endlinks. The OEM endlinks are inefficient at best and prone to bending. Pedders HD 424209 Endlinks are more robust than OEM and use urethane bushes to increase the efficiency and effective rate of the OE bar. Pedders 424109 Chrome Molly Endlinks are the strongest most effective endlinks that are compatible with the OE style sway bar endlink mount on the strut.
The best possible result is achieved when you use Pedders 9433L or 9433R GSR Struts with Pedders 424210 / 424211 Double-Ball Joint endlinks. No matter what bar you have, OE Pedders or Brand X the bar will function best with this combination of engineering excellence.
Once the foundational components are in place you will find Pedders GTO Adjustable Sway Bars to be a significant improvement to your OEM bars. The center adjustment position delivers 30mm front bar and 18mm rear bar performance. Each position you move toward the firmer setting, toward the sway bar mounting D bush will increase the sway bar rate 1mm. The same is true moving away from the D bush toward the softest setting. These bars allow you to adjust in the amount of oversteer or understeer you desire for the street or track.
