For those that are following this thread..., I changed disks and pads at the end of August 2016 fitting ATE disks and Textar pads. The pads have bedded in well and I am quite happy with them for my purposes.
Here you can see the OEM and the ATE disk side by side.
You will notice the OEM disk still has a somewhat silver coating on it and the ATE looks shiny and new.
I was disappointed to find it like this just 3 months later ( ok i noticed it deteriorating from the time i fitted them).
I know there are other better options but this was best for me at time, would have loved to have them power coated, but not sure what temp they have to bake at... So since i had a gap during the christmas period i tried my best to find High heat silver, the best i could find was rated at 400C. My plan was to paint them on the car, but then realised in order to mask properly i would have to remove the calipers, which left me one bolt away from removing them..... which i did. I specifically chose not to paint my calipers, I want to retain the OEM look.
Took my trusty drill and wire brush and spent the better part of the day bringing it back. Here you can see the difference with just a wire brush.
I then masked them , which also took more time than i expected.
I painted them and also baked them at 70degrees as per the instructions on the can, but i guess a few drives would serve the same purpose.
Fitted everything and wheels back on the car
Its been almost a month.., 2 car washes.., decent amounts of rain and now signs of any issues.
