i just looked on their site, i was wrong they are 140.. i was looking at the design of the locks and it looks like there is a decent amount of machining involved. that normally wouldnt be a problem, but i no longer have access to a machine shop anymore. . I dont plan on doing autoX so i dont have to worry about the rules and regs u have to adhear to for racing. i think it may be worth the $$ if the product lives up to its claims.
