definitely dont want the rear end loose

so its not a stead fast rule....most cars with a 275 rear tire and 275 or smaller front tire don't need a sway bar....MOST...I have had 1 or 2 that pushed like dump trucks without the bar and I had to have one put on.... even on a 275 rear wheel car, just letting you know ahead of time, I never want to talk someone into a 400-500 dollar rear bar unless its absolutely needed, that's big money that can be spent elsewhere
