I too are looking for a rotor upgrade in around 3mths time. Im sure what i currently have (standard rotors just recently machined) are fine for my driving (10km stints of start/stop) but in that 1 case that i do need to brake heavily i want to know that my gear can handle it.
No idea about any of this stuff, when i recently got new bendix pads on the back i was looking at those yellow dba slotted and cross-drilled fitted for about $1,400 or something ridiculous.
Anyway thats my story.
