series 1 brake rotors

[ben131185]

starting to feel some slight shudder again. not too bad yet but will need some attention in another service or 2.
i think i've done about 90k since i had new rotors put on, so i guess it hasnt
been too bad.

i can probably get them machined, but is it worth it?
or should i just get new slotted or drilled rotors?

i was told by a mate who had drilled rotors that they were good, til he took it in for a service oneday and the mechanic said they had cracked between the holes.

any opinions please?
