This topic will cover a 5-point roll '''bar''' as opposed to a roll '''cage'''. Most fellows these days will go ahead and build a cage while they have the welder and their tools fired up, but we'll cover the bar for those of you who don't plan on going 9's (or quicker). With an otherwise '''unaltered''' floor and firewall, a 5-point bar will take you to 10.00 flat. If the floor is '''altered''' in excess of 4 square feet (not counting wheel tubs or stock removable floor panels which are bolted, such as transmission removal panels on a pickup truck) or the firewall is altered in excess of 1 square foot, then a roll '''bar''' will take you to 11.00 and a roll '''cage''' as well as additional SFI equipment is required at 10.99. | This topic will cover a 5-point roll '''bar''' as opposed to a roll '''cage'''.
