my buddy told me that when you replace your rear gears you can get them shaved./milled for less rotational mass. anyone ever heard of this or knows how to do it? I know that they already sell lightened gear sets but it sounded like a really good/cheap idea when he told me.
Yes when you are class racing it means a lot, every little bit counts. Same goes for titanium wheels studs, saves 1.5 lbs per wheel although they run $250+
ok, yes if you're going all out racing you might need the little things to win, but if you're just using it for a weekend warrior spend the money elsewhere.
if it's just a weekend warrior then no the money can be spent elsewhere....
Like Rickki said it's not cheap if you want to do it.. The price listed are what I basically paid to get mine done.. Factor in other axles upgrades and you just spent 500+ on removing just weight..
The 5lbs on the ring gear will be less with a small gear.,., ie3.73 or soemthing the 5lbs is from a thick 4.56 ring gear
