So pad shopping and realizing I don't like replacing rotors every 2 track weekends I was looking at some lower compounds offered by Hawk. Eye balling the DTC-30s and looking at the compound chart



Notice it says DTC-30/Street Race

Now let's compare the specs between the W (DTC-30) and the R (Street/Race) comound

Race Compound Application | Hawk Performance
Street Performance Compound Application | Hawk Performance

They're exactly the same. So why are the DTC pads $30 more a set than the R compound pads that have the exact same specs. It seems they have literally put the same pads in a different box labelled DTC, and then jacked the price up because they are labelled as a "race" pad. What gives here?

Example:

Rear brakes for the s2000
R = $70
W= $95


Front

R = $106
W = $131

B serious

Are pad thicknesses or footprints different between the two? Carbotechs, for example, have a larger footprint, and more thickness (IIRC) than stock.

Replacing rotors every 2 weekends is hardcore, bruv.

RedCelica

Yes, both are .622

Here's how the Hawk naming convention works

So for the fronts using an example:

HB361R.622

HB = Manufacturer
361 = Part code (applicable to fitment)
R = compound type
. = delimiter
622 = pad thickness in thousands of an inch

dc2-2-ap1

Am I missing something? I don't see anything for an "R" compound on the chart. Is it labeled something else?

The street/race pads has shims (removable) on the backing plates and a "squealer strip" but I asked the same thing directly to Hawk several months ago:

I tried bought the Street/Race and smeared the hell out of them on the stock rear rotors and did the same to a set of DTC-30s afterward. The street/race pads wore a big groove in the rotor and actually started to make a noise similar to if you wear past the friction material and only have the backing plate or like sandpaper. I sent pics and a video to Hawk and they said the following:

I think I still have the street/race rear pads if we go to the same track day again and want to give them a go.

Wow...thanks for the info! Did they ever fade on you? What are you running now?

Hawk "low dust" pads kick off alot of dust...... just saying...,.

I didn't notice it but I probably just thought the tires were giving up. From the smearing on the rotor surface, it definitely looked like they started to fade. The front Stoptechs (w/ Project Mu Club Racers) probably just took over braking duty. The noise however was very strange because it sounded like backing plate to rotor contact but it happened after my first session on track. See video below.


Last track day I used DTC-60 in the front and rears and had no issues. I'm using a Stoptech BBK up front and URGE rear rotors. I bought a slightly used set of PFC 08 front and PFC 97 rear pads I want to try out since people say they are the bees knees. I'll be interested to see if they are worth the extra money.

So, far I've used Hawk Street/Race, DTC-30, DTC-60, DTC-70, Carbotech XP8 & XP10, and Project Mu Club Racers on the S2000. I've used Hawk HP+, HPS and EBC Yellows on other cars. I need to be sponsored by a brake pad company.

That 'sandpaper' noise is normal for Hawk aggressive pads after you get them hot and they are bedded well, in my experience. Next comes the squealing once you shave off the transfer layer from normal driving.

They make fireworks at night, too.
