Cross Drilled or Slotted Rotors or both?
Any recommendations for cross drilled or slotted rotors for a 1.8T Ultra Sport? Thanks! For now I am going to keep the stock wheels.

This question really depends on many factors (maker, size, application, etc.) but in general...
my vote is for the slotted. Cross drilled that are NOT actually casted holes eventually show signs of stress cracks...That's been my experience, may be different for others.

Thanks. I like the look of slotted better, but I have concerns on cracking as everyone mentioned. I was hoping higher end brands would cast in the holes, but maybe not.

Drilled. They preform their intended function, less weight, throughout their life, not like slots...
whose function is impared or eliminated when the slots are worn off. Mine are slotted, and I will not get them again. Incresed dust and wear are possible with either kind. The function of drilled rotors is weight reduction, although some say for cooling or out-gassing like slots, but it is negligable even in wet. Drilled rotors do not need to have beveled holes unless heavily tracked.
