Are these Amazon barbells good enough if I lift over 315 lbs?

r/homegym and r/GarageGym threads in our sources note that budget bars start to distinguish themselves above roughly 400 lbs, where whip, knurl bite, and sleeve construction matter more. Under 315 lbs, most reviewers say a well-specced sub-$150 bar is fine; above that, a higher-tensile bar with quality bushings is the more common recommendation.
