Probably what I will get when the time comes. I did alot of poly bushings from maximum motorsports over winter and they are prothane ones. For instance their steering rack bushings came in a prothane box. So if they are cheaper from prothane just buy then directly.
I run the Prothan mounts... related, sort of, I also run a Steeda strut tower brace, the prothane mounts dropped the motor about an 1/8" or so from my stockers... I noticed becuase the clerance was tight between my RAI and the strut tower brace, the Prothane mounts opened it up just a bit... no other observable differences once installed...
