Poly Bushings

[32valvZ]

Looking at doing the rears... Is there a company that has the graphite impregnated type? What have you guys used that you like and that dont squeak?
Thanks!

I understand that at the BG C4 Gathering last week, Ridetech now offers the Delrin bushings for the C4 ZR-1. They don't appear on the website yet, so you will need to call. Let us know how this turns out for you.

Be forewarned, for those who don't know, delrin (acetal) is much stiffer and will have a much harsher ride than polyurethane bushings.

Here’s a good article on the subject:

I’ve been running ES black PolyGraphite bushings for the past six years with no squeaking issues. They ride somewhat harsher than the stock rubber bushings. Be sure to liberally apply the recommended lubricant to all the moving surfaces. When finished wipe down the outer surfaces with a solvent rag to reduce attracting dust and dirt.
