Another Braking Conundrum

michaelsmiller · **Posted:** Tue Jul 04, 2017 4:10 pm

I'll be driving the Z06 Corvette in the Targa Southland this August. The Targa consists of an AutoX, a rally, and 4 track events plus 600 miles of highway driving between them. The street pads that I have been using are Hawk HPS whiles the track pads are DTS 70/60. The front street pads are pretty worn but the rear pads are new. I have not had any problem running these pads on the same rotors. I definitely know that the DTS 70/60 pads are not going to make it the whole way and I don't want to be constantly changing pads. What would be a good pad to run at the Targa?

We run Raybestos ST-43 pads on the chump car and they are amazingly long-lived and good bite. We came from DTC's, never going back.

Call up Porterfield and ask for a recommendation. They have never steered us wrong.

+1 on the ST-43s. We also run them on our Lemons car with great success. Their longevity is unmatched in our experience. I plan to switch the Mustang from Hawk Blues to these when I need my next set.

BTW, when we ordered our ST-43s, we had to wait about 4 weeks each time, so order early!

Performance Friction has an endurance compound that we have been using on the E36 Chump / LeMons car. PFC-08. We get upwards of 30 hours of racing out of them. Our car is probably close to the weight of your Corvette.

Wow, only 11 hours between the end of the CMS track session and the start of the driver's meeting at AMS.

That's right Art. Our goal is to sleep instead of prepping the car.

Last year the CMS session ran late and they started the AMS sessions earlier. And we were driving a noisy and very uncomfortable track car with no AC. It was brutal. This year Robert and I decided that we would do this in a car with AC and comfortable seats.

To answer the brake question, track sessions at the Targa Southland are short, and you get a good break between them, so you can easily run a streetable autox/crossover pad. We ran a G-Loc R8 (basically the same as a Carbotech XP-8), but could have gone with less. If you take it easy on the brakes during the track sessions, then you could probably run stock pads for the whole event.

I haven't tested them yet, but I just purchased a set of Hawk HPS Street/Race pads. They seem to be new, but I can't tell how new.

Most reports say they are essentially a DTC-30 compound with a chamfered edge and a shim to reduce noise. Again, I can't comment on how they are yet, and of course they won't match up to a DTC60/70, but they are supposedly for this very purpose. Not to mention, but the price was right!

Good luck. The PO of my Mustang had installed HPS pads on it, an after only three semi-hot laps at NCCAR, I had really bad fade. In my experience, there is no such thing as a true dual-purpose brake pad.

HP+ pads will have less fade and are still streetable. I bought my WRX with HPS's on it. They were serviceable for me at NCCAR, but the HP+'s I have on now had very little fade after 20-30 min at NCCAR. The downside is that they squeal like crazy for street driving.

Roger McDaniels · **Posted:** Thu Jul 27, 2017 8:50 pm

I never had a good time with HPS or HP+ pads on track. I've tracked both of them and the S pads were basically street pads and the + pads were slightly better. Both deteriorated immediately if I got any heat in them. There will be three race tracks on the event. If I was to use a Hawk pad, then I'd at least use a Black. Either that or brake early and easy.

I put HP+'s on the Camaro for VIR, they didn't hold up that well. Wound up going to DTC70/60 after that, they held up great! Of course I drove to the track and cold they just un-bedded themselves and then they needed rebedding but I didn't give them a chance to properly do it on track so they wound up depositing unevenly.

ChrisBarefoot · **Posted:** Mon Jul 31, 2017 7:39 am

Sorry for any confusion, but the pads I'm talking about aren't base HPS's. I agree with others that HPS wouldn't hold up at all. These are called HPS Street/Race. You can look at a breakdown here: http://www.hawkperformance.com/street-performance-compound-application

They have wider temp ranges and more torque than HP+'s and if you compare them to the motorsports chart you will see they have the same characteristics as the DTC-30's (because from what I've read they are the same compound).

We'll see how they fair.

Good for the street and the track? Next they will be saying they are also quiet and don't leave any dust. A true unicorn brake pad if there ever was one.

Haha I know, there is always compromise, and often times a jack of all trades is a master of none. I'm thinking these lean more towards track than street, but I think Hawk is saying they are 'tolerable for your drive to the track and back'.

These will very likely be loud on the street and leave lots of dust....both things I'm more than fine with for my 'fun' car.
