Ultimax: *These “Black Stuff†pads are EBC's OEM replacements.* If you're restrained enough to keep your pedal-stomping on the track and only want something for your tame and casual daily driver, these are your pads.* This doesn't mean, however, that they're not an improvement over the factory pads.* Remember those steel fibers we discussed above?* You'll find them in Ultimax pads, but only if you look closely enough.* Where many pads contain up to 50% steel fibers, Ultimax have no more than 4%.* Not 40, not 14.* Four. That means a better grip, longer rotor life, and less corrosive dust.
Green Stuff:* One step up from OEM, you might call Green Stuff pads a performance street formula.* Not at home on the track, they're polite, best suited for aggressive daily drivers, offering a softer pedal feel and low to medium dust.* They come in three varieties: 2000 Series, for small, lightweight, low-hp vehicles that generate less heat; 6000 Series, for commuting SUVs and light trucks; and 7000 Series, a higher-end version of the 6000.
Red Stuff:* This is EBC's flagship pad, probably because it's so versatile.* This is the best pad for larger, heavier cars, and those with more than 200 hp.* If you own a muscle car, drive it aggressively, and occasionally take it to the track, this is probably your pad.* Red Stuff pads do have a slight bedding period, after which they'll be more than quiet enough for the street, and they generate almost no dust, being completely free of steel fibers.
Yellow Stuff:* Here EBC pulled the friction and wear string a little further along.* Yellow Stuff pads are designed to get hotter and work better at those temperatures.* Remember, heat makes friction.* There are two variations of Yellow Stuff, one for cars up to truck weight, and one for Trucks and SUVs.* Yellow Stuff pads, in either variety, are formulated to heat faster, so they're perfect for the track, but tackle the street well, too.* They're a favorite among British police.
Blue Stuff:* EBC calls their Blue Stuff pads a track pad that can be used for the street.* They follow the same model as the Yellow Stuff, with more friction and more wear.* These are ideal for the heavy, no nonsense rigors of the track.* EBC has also found them to be extremely effective on performance SUVs such as the Porsche Cayenne and the BMW X5.* James Hallet, EBC's vice president, even uses them on his Lexus SUV, and found them a massive improvement over the OE pads.* EBC is quick to point out that Blue Stuff pads may not work well with older, single caliper systems, and is much better suited to a racing setup.
