Caltrac’s and high rpm doesn’t mix

Yellow Rose is spot on!
Your car is leaving, 'neutral'.
When you installed your CalTrac's, did you tighten the front spring eye bolt down 'tight', or did you leave 'slack' in it? There HAS to be slack in the mechanism or the CalTrac's won't work properly, they will bind up.
The Nyloc nut supplied is not to prevent the nut from backing out, it's to allow freedom in the front eye, so that the bars will work.
