I have new front rotors put on and the guy didnt put the set screws back on the rotors. I figure its not going to effect anything, but is there a reason they show be there? performance, wear? any ideas or advice on what i should do?

 

yeah at the factory they hold the rotor in place with them and then bolt up the caliper, makes it easier and faster. Don't need them after that.

 

exactly. they are a huge pain in the a$$ to any one who has to take them off. even with the proper tools they strip out
