Competition Engineering 10-Point Roll Bar Conversion Kits

If you're going to be running 10.99 seconds or quicker in NHRA, you must have at least a 10-point roll cage.

These weld-in kits consist of a top hoop, which attaches to the front of the existing roll bar and follows the perimeter of the roof, plus two supports for the front of the top hoop. Both the top hoop and the supports are made from rugged, 1 5/8 in., 0.134 in. wall, computer mandrel-bent, mild-steel tubing.
