The EBC Ultimax2 UD961 is a rear pad set for the 2003-2004 Infiniti G35 3.5 manual with Brembo brakes. The Ultimax2 line is engineered without steel fibers, making it gentle on rotors and low on dust, and it holds the GG friction rating, the highest braking-effect grade in EBC's system. Compared with stock pads, the manufacturer calls Ultimax2 a direct equivalent to OE brake pads, and it adds a cold-bite benefit that gives more bite from cold. For a street-driven G35, the R90 type approval and the Class N environmental rating under SAE J2975 are concrete compliance points that cheaper generic pads often lack.
Fitment matters on this platform. The pads are specific for 2003-2004 G35 equipped with Brembo brakes, and owners on user forums point to D960 and D961 as the FMSI shapes for the Brembos, front and rear respectively. Ultimax2 is positioned for highway use, and the manufacturer notes it is suitable for general public highway use in hot and cold climates, so it suits daily driving rather than track sessions. Long-tail searches this part answers include 2003-2004 G35 3.5 rear brake pads Brembo, EBC Ultimax2 UD961, FMSI D961 rear pads, and R90 approved G35 street pads.
These pads are listed for the Brembo-equipped 2003-2004 G35 3.5 manual. Owners on user forums say the Brembo G35 uses its own pad shapes, so confirm your brake package before ordering.
The manufacturer positions Ultimax2 for public highway use and states it is not suitable for track use. For track work, the manufacturer's racing compounds are the better fit.
Owners on user forums, citing EBC's bed-in guidance for street use, recommend driving gently and avoiding harsh braking for the first 100 miles, then gradually increasing pressure. The manufacturer notes the red Brake-In coating is designed to give safe braking right after installation, but full performance can take well over a thousand miles according to the same forum guidance.
This is a rear brake pad swap on a Brembo caliper, so it is a manageable DIY job for someone comfortable with a jack, stands, a torque wrench, and a caliper piston tool. Owners on user forums stress that Brembo G35 pads differ from other G-series pads, so match the part to your caliper before you start. Clean and lubricate the caliper slide pins and hardware, and bed the new pads in gently over the first 100 miles. Consult the manufacturer's installation instructions and your owner's manual for torque specifications.
