As always, brilliant suspension Harold. I've told you many times.
I am using a 6" / 9" swift spring with trust sheet configuration w/ vorshalg. I never got any noise until I went solid monoball front control arm bushings, and even then, its only a little soft rattle at very low speeds.
The only noise I ever noticed were when going over those super aggressive fuck-offski style speed bumps that look like this:
If I go over 5kph over those I get a little THUD on the way down but that's about it! I am using quite aggressive tyres on the street, Hancook RS-3's. A PSS tyre would be better for sure on the street.
