I've got a set of Hawk DTC 70 front and DTC 60 rear pads off my 2008 135i.
These came on the car when I bought it, and I immediately swapped them out for Hawk HPS front and rear since I never track it.
I'm not sure how many sessions they have, but it can't be more than 1 or 2.
They look nearly new (see pics).
Asking 375 shipped.
They do not include the titanium shims. Those are going back on the car.
