Soon I plan to get the carbon bonnet with RS style vents from Seibon. They recommend also installing hood pins for safety reasons, so I've decided to get a set of flush carbon latches from Aerocatch. Question is, why do some of them have key locks and some not? Is it for extra safety? Are the ones without locks weaker? I don't race or anything, so I don't have to worry much about wear and tear, if that's what they're for?
