There was also vertical and horizontal taper so the pads have also worn unevenly, in some places up to 2.5mm thicker along the bottom of the pad compared with the top. This has worn a groove along the innner circle of the rotor so I was advised to replace the rotors as well given the inner circle of the rotor is lower than the outher circle. I'll post some photos in a minute, where I think you can see the issue, including the uneven wear of the pads.

Being new to track driving this is a bit of a suprise to me but I've learnt about what people have said above, but also to check my pads more regularly, and that you really can't tell the condition from the front. My workshop suggested that I also rotate the pads due to the uneven wearing of the pads which should make the pads and rotors last a little longer. I was told that the DS3.12 pads were suited to the Girodisc so perhaps it is the level of track driving I am doing that is also wearing the pads and rotors prematurely. The events are time attack/supersprint so definitely hard on brakes, but I'd say these rotors have lasted less than one and a half pad sets, although that is probably 90%+ track driving.

I'm also thinking perhaps I should upgrade to AP racing brakes in the future and/or possibly the larger 991/992 6 piston brakes. Or maybe persevere with the current brakes and monitor more closely. Look forward to further suggestions.
