Ride quality even worse than expected. Advice welcome.

this may sound pretty basic but make sure you tighten all the components in the proper sequence and to the correct torque specs.
I have done this wrong in the past and had a similar out come.

This is a good point...and while it does seem basic, no mistake is too dumb to get by me. I’m winging every project on this car! The only help I have is this forum...so I can say definitively that I just torqued stuff in an order that seemed logical and didn’t think too much about it.
I’ll look into this! Thanks.
