I guess I am old school. I called the parts supplier and said these are not what i wanted so now i have to wait for rubber bushings.Its too bad +5 tomorrow could of had the duster back on all fours.
Lol I run all urethane, solid mounts, tied frame and it still feels like a rubber band with a motor.
5 years is the max usable lifespan for most moderate durometer bushings, don't be running rubber for 35 years guys! Unless that's your thing, idk.
