One question, are you guys concerned with the comp. springs' ability to handle lateral loads without a locating device? Even in street use I had thought it was an issue, so I installed a watts. Would love to hear your thoughts on that.

We have developed a Delrin bushing kit for these leafsprings [that will also fit any OEM Camaro leafspring]. The Delrin leafspring bushings accomplish 3 things:
1. Allows free rotation of the bushings on the shackles to eliminate the "stiction" [which is uncontrolled residual spring rate] present with a rubber or poly bushing.
2. Minimizes lateral movement allowed by oem rubber bushings.
3. The Delrin bushings are designed to allow roll articulation within the axis of the bushing itself. Some may visualize this as a "heim joint", a "com bearing", or a "johnny joint" type connection.
Our testing [with video] has not shown the composite leaf to allow any more or less lateral movement than an equivalent steel spring. Having driven a few cars ranging from OEM to true track cars, my personally calibrated butt dyno can't tell the difference in lateral movement, even with aggressive street driving with aggressive street tires.
Having said that, I think that on a true track car with sticky tires and an aggressive driver, any leaf will allow more lateral movement than a well designed 4 link/tri link/panhard bar/watts link system. That is why we will continue to offer our 4 link rear suspension for those type cars.
