Overall very impressed with them.
Short of it, they are like an EBC yellow but with less dust that washes off easier, less squeal, better cold and hot performance.

They have a short warm up period until they feel grippy. I have yet to fade them in the canyons, even when intentionally trying and with a faster setup.
Virtually never squeal unless its under 60F, and only once, then they are silent.
The dust is really low too considering, much less than OEM german cars, and its washes off very easy.
Not very hard on the rotors either, some wear but very little considering how it's driven.

If needed they even have a track series, and ceramic for lighter duty.
