The Quieter Alternative to the S5 Kit
This kit saves 15 percent over buying the pads and rotors separately, with caliper lube included. Its main advantage over EBC's S5 kit is reduced wind noise, thanks to the fine-slotted USR series rotors used here instead of the wider-aperture GD series. The kit includes EBC's flagship GG-rated Yellowstuff high-friction pads, built for maximum brake effect, fully shimmed, chamfered, and slotted, with the patented Brake-in coating for fast pad seating. It's the kind of detail EBC backs up with actual testing rather than just claims.
Same Flagship Compound, Quieter Rotor Choice
Pairing that same proven Yellowstuff compound with the quieter USR sport-slotted rotor gives you nearly the same maximum street performance as the S5 kit, but with noticeably less rotor noise at speed. That makes it a strong option for anyone who wants aggressive street braking without the extra wind noise some slotted rotor designs introduce. It's a genuinely considered tradeoff rather than just a different rotor swapped in at random. That's worth keeping in mind whether you're upgrading proactively or replacing a worn part.
