It's an easy piece to do in a lathe,using a poly as reference every machinist in a common shop can machine a one-piece rubber bushing instead of a two piece poly (talking about front a arm bushing).You have to source a rubber rod 2" diameter to machine and... to pay

Almost all of the bushings required machining to properly fit their designed movement.
Frankly if you soaked these in whale blubber they will squeak like an old railroad car if not properly installed.
Still my suspension does make noise. And when it does, a liberal dose of silicone spray helps to reduce it.
I also added a set of Borlas which assists to divert my attention.

When I was assembling my suspension with poly, my first step was to ensure the pivot points were not in a bind.

he did the bushings by himself becouse he has a machine shop,a simple task for him,just buying a rod of industrial rubber and some hours labor saturday afternoon.Probably in future if lot of C4 ower want rubber bushing some vendor will put in production this stuff...

Also i think when you buy poly bushing you know this stuff is harder than stock,squeeks are on the list of compromises..btw lot of guys here haven't any issue with noises...i think a good greasing is the key,zerks are a good investment for future and a good grove machined on the poly to allow grease dridtributes itself is good too. When you put stuff like this you have to think about confort and cruise....
beautyfull stuff for autoX...but on the street ...Lot of good materials out there for stiffer sharp handling, never heard about Delrin or Teflon bushing?...or this aluminum/teflon on pics, but you know what you put into your car...

He said he had to make some trial to get a balanced interference between outer interference, rubber to A arm, and inner interference with the metal bushing. As you can see he used the lathe wise and mandrel to press in the bushing.He said wasn't a PITA press in the bushing,just silicone oil and a pre- warming in hot water.

I also grooved and added zerks to all my poly bushings, no noise what so ever.
