that is for the heavy duty Zimmermann's which are balenced and are lasting a long time on my car which are lasting a long time...and they for the rears..

Drilled Rotors : Expensive. Best cooling, noramlly used for track events. Some dealers just drill holes in stock rotors and don't "treat" the rotors to re-harden them. Holes need to be chamfered(SP?) to prevent excessive wear. Turning next to impossible? Best are rotors with holes cast in place during manufacture ($$$). Reduced braking during normal use due to loss of surface area (holes).
Slotted Rotors : Less expensive, help throw water, increased bite into pad, better braking during normal use. Turning, I don't know.

Holes and slot's also create weak points..i perfer the solid heavyduty Zimmermann's that i have..BMWSLYR in WA.

....weak points around the perimeter of the hole. Drilling actually weakens the material approx. 1/8" in diameter around the exterior of the holes.....that makes for quite a bit of weakened material in a drilled rotor. Therefore, if the holes are drilled the rotors have to have been specially "treated" to hold up properly.
On the other hand, if the holes are cast into the rotor this "extra" weaking around the holes doesn't occur. With casting the holes it is also less important to "treat" the rotor. Thus, cast-in rotors are generally stronger then drilled rotors.
If you really want a cross-drilled rotor make sure the holes are cast-in!!!
