BLUF, there is no perfect solution to e39 front brake pads. I've had the OEM (Jurids), Axxis Deluxe & the Akebono Euro. All have positive traits and drawbacks.
Jurids - Hands down, the best braking performance, feedback and linear feel of all pads. Quiet too. But dustier than a coal mine and nearly impossible to clean off a Style 42.
Axxis Deluxe - A good compromise between decent feedback and linear feel with relatively low- (but not no-) dust. But they tend to squeak, requiring periodic rebedding.
Akebonon Euro - Virtually dust free and super quiet. However, the feel and feedback is lacking. No initial bite, requiring nonlinear braking pressure. You adjust and get used to it after time.
Post back if you get the Hawks. After the Euros, I may go back to the Axxis (now PBR).
