If all that stuff comes with the TC4 Team kit, the only things to buy for the factory kit are gonna be titanium turnbuckles and bearings, maybe that air intake thing. Personally I run stock so the intake is probably useless and more weight than it's worth. Bearings, I could always buy ceramic ones. Titanium turnbuckles, I guess I could buy them but they're not absolutely necessary. I doubt anyone ever won or lost a race because their turnbuckle was steel vs. titanium.
What do you think?
