Rotor suggestions

Because I always need to spend money on my car, my front rotors are warping, so I need new ones. Any suggestions for running stock?

man, give me a set of new rotors and I can kill them in a day.... You wont be able to machine them back out they will be so warped. And FYI cross drilling is bad. Even to the point of unsafe if you DIY.

For the OP, a good set of pads (Hawk HPS, PBR Ceramics, etc.) new discs and good fluid is perfectly sufficient.

Just curious why you consisder cross-drilling bad - it's what I have now, and wondering if you can point me to a supplier for the pads you mention, or even for good rotors.

Thanks.

A hastily quick explanation, The reason of the rotor is to absorb the heat created from the brakes... And when the rotors are drilled, there is less overall mass, meaning they heat up more quickly, being that a culprit of brake fade. Secondly, the crossed drilled crap is noisey when you really romp onto the pedal... also think of it as a cheese grater eating your pads. Three, after extendedly hard use (ie Track useage) cracks develop around the holes, which can be dangerous to a certain degree if the rotor actually ends up cracking in half. Wouldn't be a pretty outcome me thinks.

As for where to get the parts, any Shop would be able to hook you up for the stuff... namely, Bimmersport would have decent prices I'd imagine for parts. Also I think our maXbimmer sponsors would be able to hook you up (Corner73). I can also get you a price on parts from my shop if you'd like, but I doubt they will have better prices...

Thanks for all the info everybody. My last BMW, a 325e, I set up with slotted rotors and PBR pads and they had a hell of a grab, so I'm trying to get back to that feel. I think I'll try normal rotors to see if there's a noticeable difference. Anyway, it's snowing and I don't have a garage. I'll have to put up with the shakes for a couple of weeks.

Cheers.
