Hawk DTC-70 vs EBC Bluestuff

[jnag]

Looking for opinions on which of these pads is better suited for a street/track dual duty pad. I know there's better options out there but really would like something I can get through FCP euro so I can take advantage of their program and I ended up trying to decide between those two. Any input appreciated!

I’ve run DTC-70 front and DTC-60 rear in my M4 and they were great as track pads. They’re extremely loud however so you probably wouldn’t want to use them for everyday driving. That said, they work fine from cold so they’re not dangerous on the street, just annoying.

I use the DTC70 as my track pad, then drive it on the street a few days a month and back and forth from the track. If you don't grease them properly they are extremely loud. Tons of brake dust as well. I really don't think they are ideal for a daily driver brake pad. And honestly I don't think there is any single brake pad that's good on the street, and good on the track. If i'm driving a bunch on the street, I'll put the stock pads back in.

The EBC Bluestuff X is a high performance street compound that supposedly can be used for light track use whereas the DTC70 is an aggressive street pad with a CoF around 0.70. In my experience there are only street compounds and race compounds, no dual-use compounds. For example, the Ferodo DS2500 is supposed to be a dual-use pad but I can completely wear down a 25 mm thick pad in fewer than one day. Light track work implies braking early and easily which actually drives up braking system temperatures and, therefore, increases wear rates. EBC Bluestuff probably wears faster on track than the DS2500. The DTC70 compound needs temperatures above 400 F before they start to generate CoF levels that produce good braking torque levels; however, consistent street braking system temperatures reach only 200 F so the DTC70 never leaves the abrasive braking method. This means your DTC70 pads are acting like an aggressive brake lathe, which means they are quickly wearing away rotor thickness, and are not generating significant cold braking torque. Additionally, the DTC70 compound produces a massive amount of high metallic content brake dust, higher than stock pad levels of brake dust. It is easy and quick to swap pads on the f8x so I’d order from FCP Euro a set of EBC Yellow for street use, and DTC70 front and DTC60 rear for track use. Note: the DTC70 is an aggressive race compound and requires extremely sticky tires, and ideally a proper track suspension setup, otherwise it will immediately engage and confuse the stock ABS system.
