When my brakes warped I got DBA 4000XS rotors and Hawk HPS pads(C5 in the fronts). One of my rear pads cracked and bit into my rotor, so I replaced the rears with DBAs again and EBC. A few months later, a Hawk front cracked and trashed a rotor, replaced rotors and pads with DBA and EBC.
I'm using EBC red pads and like them more the Hawk, preforamnce and quality. DBA rotors I would also buy again. EBC also has less brake dust.
I used nothing but EBC in the past decade on all of my past and current cars.
My friends that tried Hawk will say that although they grab great, they do chew up the rotors pretty bad.
This is highly unusual as until now Race Pads have been built with no regard to disc wear, noise, harshness, bite from cold and certainly never tested and passed brake safety tests for Highway use such as Europe’s ECE R 90 Brake safety test.(see note at bottom about street use in Europe)
The biggest advantage of the new EBC Bluestuff pads is their bite from cold and progressive feel. This is achieved by blending with specially chosen man made naturally mined fibers which are much less harsh on rotors than semi metallic fiber used by ALL OTHER Race pad builders.
Deep V grooves help venting and catch dirt, dust and debris. Notice the open granular surface texture after the heat scorch (pre-bedding) process.
The GTO in Australia is known of course as the Holden Commodore and this very quick version shown above run by Emotional Engineering in the British GT series ran EBC Bluestuff throughout the long 1 hour races in its season. It also performed excellently in the FIA GT World series in France.
For several years EBC Brakes has been developing its full race pads for cars called Bluestuff and after a few final modification in 2009 is preparing to release this material known as Formula NDX in fall/autumn 2009 for the 2010 season.
The NDX Formula is a harder and longer lasting pad than its stablemate the Yellowstuff compound and has been very succesfully run on heavier cars including the Holden(Vauxhall) Monaro which weighs in at over 3600 lbs ( almost 1.7 tons) and as such is a much better test of the typical "3000 pound" USA race cars.
Whilst EBC Brakes Yellowstuff has worked out very well in Europe on Trackday and short even closed circuit racing its high friction characteristics cause it to wear quite quickly on heavier cars and longer races, making the Blue NDX grade the ideal upgrade.
EBC Bluestuff USA ......First test weekend with Race Driver George Penn (who's purported to be an EBC employee) in a 4000 lb stock GTO at VIR in USA. George ran 3 x 45 minute sessions on the E 366 compound EBC Blue before finally toasting the pads. The EBC formulation was then upgraded to enhance life and is being retested shortly. The stock PBR caliper only allows a 14.0 mm pad which is not enough for a car of this speed and weight and encourages us to caution drivers to monitor wear every 120 minutes of trackday driving on the GTO.
"Wow, the way the Blues performed this weekend were well beyond my expectations. I had to completely relearn brake zones because I could push so much deeper. The performance and durability of the 2081s was leaps ahead of both the old formula and the HT-10s I cooked in the prior weekend. I can't consider my brakes a weakness anymore and I should be on the podium every single event. The Blues even have me thinking I should keep the beautiful 14" Stoptechs BBK in the garage so I don't get bumped up a race class."
