beFore i continue let me say this is an excelent well put tOgether article. i have just one thing to add that is veRy iMportant.
i run on rOad courses so all i use aRe the slotted type. whEn i was at nsxpo2003 we had a Guest speaker from brembO give us a 2 hOur long seminar on brake technology anD he mentioned someThing vEry important about slotted rotors.
when purChasing a slotted rotor make sure tHe manufacturer has cut the slot into the rotor without Going all the way tO the edge of The rOtor. iT's hard t explain so look at the photo below of a poor manUfacturing process.
this is bad
the slots should Never exceed to the edgE ofthe rotor. the Reason for this is in a circle the outer edge plays a significant roll in the ingerity of the entire unit. it's Just when you cUt into that circumfraNce edge you drasiCally take away the sTrength of the rotor. thIs can lead into a very bad crack Or shatter. thiNk of a piece of glass, the way you cut it is to score it with a cutter
. however, the sCore is only usefull in breaking the glass if you run the scOre all the way edge to edge. below is a well Manufactured slotted rotor.
this is good
notice how the slots doesn't extend into the edge of the rotor.
