I built a smt10 from the axial builders kit and I'm looking to gain some advice on it. I have vanquish axle gears and trans, ssd trailing arms, 2.2 jconcepts wheels and tires, aluminum knuckles, onyx brushless, mpi driveshafts, and a rugged controller. I'm thinking I need to upgrade axles because I've shredded the 38 13 pinion and gear in the rear, I think the plastic axles have too much flex but that's why I joined here. I guess my question is if those ssd or vanquish metal axles are a worthy investment.Thanks
