Literature from "unbiased" sources that "sell" the said parts... heheh...
Do you think they would tell their potential customers NOT to buy the more expensive rotors... Wake up...
Less surface contact area = less friction = less stopping power. (simple physics)
It also equals significantly lower rotor life due to cracking from the heat cycles.
Cross-drilling = fashion statement on street cars.
Why?
Since we do not use any exotic materials for pad and rotor manufacturing that cause extreme amounts of excess gasses to be created. Not only that, but slotting the rotors more effectively evacuates these gasses than cross-drilling does, leaves more contact area and is not prone to cracking like drilled rotors are...
