Hawk LTS - FF
The Hawk LTS pads I just put on today were marked FF on the back.
The OE Pagid / Brembos I took off were marked GF.
The LTS pads are not what I'd call fully bedded yet, since I can still see some machining marks on the Zimmermann rotors, but already feel about the same as the OE's to me. We'll see how they feel after a little while.
An annoyance: the OE rotors I took off were the most severely lipped I've ever seen (my basis for comparison is Subarus, US cars/trucks and various Korean/Japanese cars). I suppose this can be attributed to the abrasive OE pad compound. The lip, rather than the face of the rotor, actually cut the wear sensor. I think I could've had another 5k miles on these pads if not for that. Oh well, no harm in being conservative and replacing them early (except to my wallet). Here's hoping the LTS / Zimmermann combo lasts a little longer, without the lipping, and the perfrormance is good.
