Without a transmission swap, look for taller wheel/tire combinations to reduce RPMs at freeway speeds. Honda lists the factory tire size as 195/55-R15. I am confident you can get a 16" wheel that will be as light or lighter than stock and bolt onto your 4x100 hubs. But even with your existing wheels and stepping up to 195/65-R15 gives you a 4.2% reduction in freeway RPMs. Go to a 16" wheel and use 195/65 tires and you'll prolly get 9% or 10% reduction. Good luck.
Iím currently running a 205-50-15 on the car, Ventus V2 concept 2 (H457) Tire Info | Hankook Tire USA is what Iím using currently. Probably the wrong choices size wise for rolling resistance and aero on that car, I switched to that size years ago, this set is almost brand new though so itíll be a while before I can switch
