bump steer?
I'm looking to lower my 2003 Z51 about an inch. I love the way it handles, but i still get some bump steer when i hit some uneven pavement under heavy suspension load. Has anybody out there had any experience with bump steer issues with a lowered Z51? I'm also considering buying/fabricating a "bump steer it" like the one Zip's sells to help combat the issue. Any input?

Have you measured the suspension for bump steer? Bump steer isn't the only cause of a car steering itself over bumps. With these cars, it's more likely you have a tire or alignment problem than an actual bump steer issue.
Not sure about you, but I personally want to confirm a problem before I try and fix it....

Especially effective for lowered cars, but beneficial for any C5 or C6 Corvette that has modified suspension geometry. Allows adjustment of tie rod-to-spindle attachment point to help eliminate "darting" that occurs when a loaded suspension reacts to road surface irregularities (seams, potholes, etc.). Allows for suspension to be "dialed-in" to maintain correct geometry throughout full range of suspension travel. Zip's bump steek kit includes a pair of rod end bearings, sleeves and hardened pins to replace outer tie rod ends. Fits all C5, C6 and Z06 Corvettes.
