Sway Bar Opinions?

Jim Lusk said
Bars come with different mounting arrangements. Some use factory location tab, others use a bracket that mounts to the strut rod, while others have a bracket that bolts in with the lower shock mount bolt. All will work. Sway bars and larger torsion bars will hurt your 1/4 mile performance, but help everywhere else.
how does a sway bar and larger t.bars hurt ur qt mile performance, more weight transpher to the rear???? :silent:
