EBC UPR7301K Rear Ultimax OE-Style Disc Rotor Set 2005 2006 Pontiac GTO

EBC manufacture many of its rotors in either its own sister company foundry in the UK or in Italy, all rotors are machined and finished in the UK and in the USA. Where castings or finished rotors have to be bought in to complement the range, the strictest quality controls you can imagine are applied to ensure the safety and quality of the parts we sell. There are zero aftermarket casting companies active in the USA much to our regret. The castings we source come mostly from our sister foundry in the UK by a large margin, then some from Italy, some from Japan, some from Australia, some from the Czech Republic and some from China. We source quality parts from well known and proven vendors and we are responsible for and guarantee those parts to fit and perform as expected.

EBC adds value to its products by strictest quality controls and specifications and a 100% run out and dimensional check, plus all USA sport rotors are slotted at the Los Angeles facility of the USA operation. Apart from our UK and Italian made rotor ranges we now purchase a percentage of our rotors from China from a factory that we have personally visited, accredited, made extensive checks upon and have an agreed quality protocol of the finest quality this modern factory can produce. We work in harmony with this new vendor to ensure highest quality, through inspection in both dimensions and metallurgy when the products arrive in the USA.

EBC also does all they can to embrace US employment and in our US facilities we employ 14 people in our rotor machining facility alone.

All EBC Premium Discs are cast to a material strength of 150 N/m2 with a tightly controlled surface hardness variation less than 20 HB and are precision CNC machined to a surface tolerance of less than 0.05 mm. That is two thousandths of an inch. For this reason EBC recommends a maximum runout of fitted rotors of 0.1 mm or .004 inches (4 thousandths) TIR which means total indicator reading on a dial gauge.

EBC Automotive brake rotors are made from G3000 spec cast iron and full specifications and properties can be seen here!

Runout figures above this will lead to vibration after 3000 to 4000 miles due to what we call disc thickness variation (wearing a thin spot on the high point of the rotor as it runs off-true) which is not a warranty condition.

So you see this is no cheap import brake disc. These brake discs have the highest integrity and product quality on the aftermarket. An OE quality replacement disc, made of the finest grade iron and a perfect replacement disc for any car.

Every EBC rotor is runout inspected on this machine. Even when manufactured on state of the art precision machines, not even ONE single disc escapes this process guaranteeing perfect disc alignment. If during install you notice runout on your car it will surely be due to a chassis alignment that happens on one in seven cars, usually cased by nudging a kerb or hitting a pothole in the road earlier in driving the vehicle.
