20% what?
Last 20% less than a full face rotor maybe.
20% less contact area vs full face???
Doesn't less contact area equal less stopping power and more heat (which equals greater fade & less stopping power)
Cross-driling is done to lighten unsprung weight. However race/track cars have 15" brake rotors or so. That means a significantly greater contact patch even with the holes drilled compared to our litle 11" full face rotors...
If you want to vent the gas built up between the pads and rotors then get slotted. However unless you do a lot of autocrossing (or true back road) driving you realy wouldn't notice any difference in fade...
