I have no issues with Optus reception around Melbourne, only when I head out bush. Which is a fair few times a year.
You can get cheap movies tickets with RACV as well.
Too be honest I've never used drilled rotors before and I've only ever seen them crack on track cars.
If you can get them at a decent price then you should be fine. I'd just keep an eye on them after some hard driving.
Steer clear of drilled and slotted and stick to factory for the street. Or just slotted rotors.
Drilled rotors tend to crack, however if it's just on the street you may never get them hot enough to see that happen.
