The 4-Link bars on my car are adjusted a little over 1/4" shorter on the drivers side than on the passenger side. Also, the rear axle is not centered to the chassis/body. Distance from the axle face to the chassis centerline is close to 3/8" longer on the drivers side than the passenger side.
This is how it was set-up when I bought it. I have had it out to the track a couple times to workout bugs & have made two semi-hard runs. It drove OK. After these two runs I noticed the drivers side rear tire was rubbing on the body. I was measuring things before changing 4-Link settings to get a little more clearance on the drivers side.
Should The 4-Link bars be equal length & rear axle be centered?
