From Hawk's website: "The new Hawk High Performance Street/Race brake pad compound ... is the ultimate high performance, street brake pad! Perfect for aggressive street car owners that also use their cars for autocross, HPDE, open track and time trail racing... It performs flawlessly at all temperatures and operating temperatures range from 100-1200F with superior torque while providing a consistent feel and characteristics." Some of this piffle may be true... but THIS Fiesta ST owner was disappointed in a few ways. Before I get to that, I'll say this: the pad DID provide a consistent feel and characteristics throughout the indicated temperature range. But so do the stock Ford Fiesta ST original equipment pads. But that's not all these STREET/RACE pads do! They also squeal excessively, create excessive brake dust, and they score your rotor horribly. The grooves were as bad as a complete absence of brake material might cause. And that was in just three days of commuting, BEFORE I took them to the track. Here's what the pads don't do: They don't last any longer than OEM pads on the track. They don't stand up to heat any better than the OEM pads do on the track. So why pay $120 for these, when $72 gets you a new set of OEM pads that perform comparably, create less dust, and make less noise? Now, I believe the Fiesta ST is particularly hard on brakes because it uses them under acceleration in its Torque Vectoring behavior. The brakes never get to cool off. And it's particularly hard on the brakes on shorter tracks with lots of elevation change, straights, and braking zones, like Summit Point Raceway's Main Circuit in West Virginia. To make things worse, Hawk is experiencing a manufacturing issue with the Fiesta ST fitment of this compound, causing uneven wear if installed without a slight modification. But let's assume Hawk quickly addresses this problem, issuing new ones that have been manufactured correctly with different INNER and an OUTER pads. Also, let's assume you have addressed the heat issues with cooling ducts and/or a mechanical limited slip differential. I still couldn't recommend this compound to you, primarily because my rotors are so groovy now that I can't safely change the pads without addressing the condition of the rotors. I will probably have to turn the rotors or replace them altogether. Run away.
