I have seen you mention the Heigo rollbars in some previous messages but I did not think that they are PCA legal, because their diameter is only 38mm (approx 1.5") and the wall thickness is 2.5mm (approx 0.090"). I thought the PCA specs were 1.75" and 0.125" respectively. Am I correct or are they legal for PCA time trial and DE use? If they are legal, is their smaller dimensions allowed because of the type of steel that is used?
