Are you able to share some more details regarding the noise from the AP Sprint kit? I thought noise was mostly a function of race compound brake pads more than anything else.
The only other complaint I've heard about the AP Sprint kit is that not having any dust boots makes it an issue for year-round driving and likely requires frequent servicing. When you took off your kit, what did the pistons look like?
Anyway, not familiar with the noise so please share your experience
