If the belts they are certifying are losing 1/2 there strength in one year they need to up the standards of the belts not make you replace them every two year.
Nothing but a money grab pure and simple.
Like I said- A joke that 40 year old belts that have sat out in the sun for decades are ok to make a pass with but 3 year old 3" race belts are treated as junk.
