Brake Rotor wear and slight scoring HPDE

Rangerz

I did some searching and their seems to be some debate on resurfacing rotors. I have run 6 track days this year on the OEM rotors and EBC yellow stuff pads. The pads have 3/8 to a 1/4 " of material still left and will need to be upgraded after my next event 6/29. Both my front rotors are showing slight groves on the contact area so not sure if I should bother resurfacing them or continue to run them. Both discs are 1.26" thick = 32mm.

I posted this here because I think the track guys will have encountered this more often than anyone else.

The grooves are smooth edged and probably .005-.015 in depth. That,s a swag measurement I don't have needle tipped micrometer for getting down in the groove.

So what would you do? I planned on the Z1 2 piece rotors but, wanted to get through the year on the stockers.

Here is a pic of the front passenger side disc hopefully you can see enough detail.
