I too have looked at all the options in an effort to attain higher hwy speeds and concluded that w/ all that would have to be done to achieve that, it’s simply not worth it, b/c #1 The expense and cascading effect on other components of the drivetrain, etc. and #2 there’s nothing like original equipment. I concluded I’d keep everything factory original, w/ exception of the split-rim wheels. Good luck. I look fwd to following your decision and course of action.
Thanks for the details Robert! I am most definitely staying original. Two weeks in with this 305 and I'm very pleased with how it runs. May look into power steering options, but other than that just some cosmetic changes in the works.
