Been feeling quite some vibration under braking recently. So I measured the runout on the discs:
Left hand side: https://youtu.be/UVuKTQnlDL8
Right hand side: https://youtu.be/zroEwP6wpLM
The left hand side is the worst although I do not know how much is acceptable. So, ... new discs it is. Here's the question that has been asked many times however I still cannot decide on what to do.
Should I upgrade the disc/calliper setup to a different setup (vented/4pot) or should I just get new discs (which brand) ? For info: I do enjoy racing through winding roads at times , also planning to go to track a couple of times a year.
Hope you can help
