I went through standard pads in 3 track days. I then put orange pagids in front and blue pagids in rear (on advice from local Porsche Motorsport). These lastest about 10 more track days so much better, and orange and blue was spot on as the pads wore evenly. My car has now done 14,000kms and I have just installed my 3rd set of pads. Rotors have some cracks but are still OK. Factory tyres are only 30% worn, but I have almost been through my first set of track tyres. The race pads squeal like crazy. I leave them in the whole time.
