I'm curious - what types of wheels did you use? We have slicks in front and stickies in back; I'm convinced the extra grip in the stickies can exaggerate the frame bending. Do you feel the same way?

We only used kit wheels during this process, but they were rotated rear to front and back during the process. The problem always followed the sticky wheels. Presumably this is due to the higher coefficient of friction causing more tension to develop in that chain. Good luck at IRI.
