If anyone is interested in the front upper bushings, I have a few sets to sell for cheap.

In the rear suspension I have mostly spherical bearings for the joints, as it's simply easier to purchase high quality parts that are already available.

Considering the low cost of installing delrin/aluminum upgrades, and sometimes restricted by rulebooks, it's a simple upgrade. On the downside, there can be occasional noises either from road conditions or a lot of suspension articulation.
