Personally, I've has zero braking issues of any kind.
It sounds like "UK" was pretty responsive considering they gave you a new set of rotor rings (and hats?) at the same time they shipped your original rotors back to PFC USA - didn't leave you rotor-less! I hope once they've had a chance to examine your rotors (and hats) they'll have an answer for you  |
Good to hear that your kit is working great for you, as i'm considering returning the discs and getting their front kit for my track use. I'm just perplexed as to why the first set of PF discs were defective in the first place; they were spinning elliptically causing vibration, and this was immediately after fitment. They were properly installed on a clean hub too and weren't loose.
