Unfortunately I forgot one small but important detail... oem rotor thickness. My buddy measured it and the fronts were at 28.7mm. The minimum being at 28.4mm, I was told the stock rotors won't survive the summer with a few track days thrown in there. I knew my rotors weren't perfect and was only hoping to make it through this year with them.

Now... should I just get oem rotors since I have brand new pads (less than 30km driven on them) in there. OR bite the bullet and get BBK and sell the PFC pads? Yes yes, I know I don't neeeeed BBK now but I' planned on getting them some day and I will be doing more track days down in the future.
If you can find a buyer for the pads I say go for the BBK as the consumables are cheaper in the long run. If not the oem rotors with PFC are a decent package but they will eat the oem rotors rather quickly.
