When I re-build my front suspension I am minded to use PEEK FC30 for the bushes which is a high performance thermoplastic used in the automotive, aerospace and oil and gas industries for bushings and other high wearing parts. Better than Nylon and I think would be better than Vesconite, it's only draw back is its an expensive Thermoplastic but it wont swell, is chemically inert to oils and greases and has a continuous use tempreature of between 240 and 260 degrees C.
