Xoxox has released Friction, a new VST designed to synthesizer friction effects:

The friction algorithm is combined with a 2nd order mass-spring and two waveguide resonances for flexible emulative application.

Presets include squealing tires, squeaky hinges and axles, ww2 bombs, swingsets, etc.

The license is $15 (or $10 for current customers). The demo removes some parameters.

Preview friction below. Note: it’s pretty painful:
