Cross drilled rotors

Are cross drilled rotors worth the extra $$
or am i better off using oem ?
thx

it would seem that the cross drilled would stay cooler during braking therefore adding life to the brakes

I've heard arguements both ways. biggest thing, it depends on your type of driving conditions. if you do constant city driving with losts of stop & go, they may help a tiny bit. but if you do highway driving, the large amount of air movement will help keep the rotors cool.
And it also depends on your braking style. I'm not saying they do/don't work, but with alot of things, you won't see much of a difference if any.
A few things to think about.
1) Should you decide to buy them. The upkeep can be a bit of a headache. Being holes in the rotors they are one of the first places that brake dust goes, and naturally, over time, the brake dust builds up inside the holes. slowly closing the holes and minimizing any effectiveness of the holes. If you get then, it's best to clean out the holes every brake job. very time consuming.
2) if you get them, make sure the holes are tapered. if they aren't tapered, most places will be unable to turn them. and if they are able to turn them, the amount/times that they will be able to be turned depends on the tapering of the hole. They rotor may be thick enough, but once the taper is gone, they can't be turned.

My advice, stick with stock.
