ordering arms "SPOHN" TUBULAR UPPER FRONT CONTROL ARMS (TALL SPINDLE SWAP) which are better for daily driver and longevity high durometer polyurethane bushings or •Optional Delrin bushings for zero deflection and maximum handling performance ?
LS6 Tommy said:Poly isn't bad for the front A-arms, but it does eventually turn to mush. Were talking over a LONG time, but it happens. That's why its not used on any OEM suspensions. For a weekend car, a street/strip or any other occasional use vehcle it's fine. IMO it has no business being used on a rear 4 link at all as it binds the rear suspension up pretty well. I'm on board with the Delrin.
