I just don't understand why hasn't anyone, including Paxton improved this issue with some sort of Cog drive system on the most highlighted pulleys. I imagine not every single pulley on the system and bracket would require a "Toothed" design but damn! Maybe that would drive this kits price beyond their intentional design. Idk, I have always ready and known of the "Infamous BELT SLIP" through all these years and just surprised things haven't changed. I am one that would like to chase and reach 700+ just seems to be more of a headache and not worth it for the belt slip.
