Poly lower bushings and poly Struts? I had poly parts and aftermarket upper bolts with a spool. After a couple years of foot braking I lost more than a tire and fender. The bolt failed on the left side. I have videos of the right side basket balling forward on the launch when the wheel would leave the ground.
It never did that with standard bushings and bolts. You could actually feel it in the steering wheel after they were install. The bolt was the final issue.
A couple of times when I had the car on the lift I noticed the torsion bar clip was gone on the left side. I replace the left side twice. The poly bushings were always walked off the pins 1/4 inch. We were in the process of installing a tube K-frame when this happened. One last ride was all it took. The poly strut rod nipple that slips through the K-member was sheared and gone and the one side was split like a watermellon dropped from 20 feet. Tear it a part you won't see whats wrong while together.
Yes a spool does play hell on parts . OEM parts will last longer under extreme stress.
