new rotors need machining?

[vinnY]

got some new slotted rotors a few months back
just wondering whether i should have gotten them machined when new or not and wether its a good idea to get them machined now even though they're been used for a few months

They would be machined from the manufacturer. Why do you want to machine them again?

Do the brakes shudder or anything?

Did you get new pads when you put on new rotors?
If not then the old pads would have been molded to the grooves on your old disk thus on the new disk the brakes will be ass

Shouldnt need to machine them.
