My car was certed for 7.50. 3 yrs agoso had to havea recert done and was told that the front two bars of the cage are not laided back far enough ( can' t remember if he sad the bars needed to be at 22 or 25 degrees) so I have to add a couple of diagonals in the corners of the cage to the top frame loop.
Does'nt affect me,but was also told if the car would have been a 6.0 cert that I would need to add kidney bars from the rearend upright mounts all theway around the back of the car. Which would have made it impossible to remove the rearend.
Just wanted to let you guys know what I had heard so no one has any trouble recerting their cars
