I have read that cross-drilled and slotted rotors used to benefit braking quite a bit with older brake pad compounds, but with newer-tech quality brake pads they won't do much. Most quality slotted rotors cost quite a bit more than stock Balos. The only cheap ones I have seen are ATE power discs, but have read from many that Balo's are more warp resistant that the ATE's. What do you think?
