Any thoughts on these pads for a street car that is also going to see a few tracks days?

I run the Hawk HPS ferro carbon pads on my car on the street and I really like them. Quiet, and they stop on a dime. They don't fade out when hot like stockish pads do. I run them with a set of ebay slotted rotors. They work good to slow me down at the end of the dragstrip too, from 130+ down to 15 to turn onto the first access road. I keep telling myself to not brake as hard and just use the 2nd or last access road, but when going that fast, my brain automatically tells my right foot to make sure we make the first access road to leave room for error. That said, the brakes are holding up fine to the abuse.

Yea, Andy, get them. If you're rennung stock pads, you'll see a BIG improvement. Some guys like the HP+ better but, they aren't recommended bu Hawk for street use because thay can be noisy and take a bit of heat to work properly. To do it right, you need to clean up the rotors first. I'd recommend getting the 2 inch Roto-Lok scotchbrite discs. You can find them at the autoparts stores made by 3M but actually, the Harbor Freight kit has a better disc holder. The kit is about $15 and can be used with 2 in. sanding discs so, it's nice to have in your garage. It will work with a regular drill. You need to clean the rotors to remove the adherent layer of brake pad material from the discs. This can be done on the car, remove the calipers and scotchbrite the discs, it's OK if the discs spin while you're doing it. Takes about 15 minutes to do all 4. Then you need to do a proper bed in. this will put a new adherent layer of pad material on the discs. There are instructions on the Hawk box but I take it a bit further. The first part is to slowly build up heat in the pads and discs. Make 3 runs from 30-40mph down to 10 mph with just light pedal pressure. Then make 2 or 3 runs with moderate pedal pressure. As you head home, make 2 very (Very) hard stops from 60-70 down to 10 mph. Don't completely stop the car on any of these runs. Try to make the last, hard stop close to your driveway if possible. The park the car and let the brakes return to ambient. It's also a good idea to move the car a foot every couple of minutes to move the pads to a different location on the discs (about 5 times). You should be able to smell the brakes when you return, that lets you know you got them hot enough. Doing this will put the correct layer on the discs and go quite a ways in preventing "green pad fade". At the track, the HPS will be much better than stock. But, you may experience some brake fade with these compared to HP+ or better pads. This is usuallt caused because newer Corvette drivers overuse the brakes at the track and build up too much heat. I run my C4 with HPS when I take students out with no problems but I brake hard with short duration. I'd also change the fluid to some good stuff if you haven't done so. |

I have used both. The HPS is good... and now I have the HP+. The + are noisy as hell... and dusty... but by God they stop.
They stop on a nickle and make change. You breathe on the pedal, and you can feel yourself coming off the seat. Just insane amounts of stopping power. They do need a bit of heat, but here in SoCal, it's not an issue. I have no idea how well they would work in sub 50F weather. I do know they get warm after a couple of touches, but even cold, they stop insanely well. I use the HP+ with cryro-treated powerslot rotors in the front, and premium NAPA in the rear. |

Thanks for all the replies, think I will make the change out before I do a track day. I am running Bosch ceramic pads now and from what I have read they would not be a good pad for a track event.

Nope, ceramics are nice street pads but definately not for the track. And with ceramics, you need to get that layer off the discs so that you don't inbed it in the new pads. |

Bill, I will likely be going with new rotors as well. Present rotors look and feel smooth, but they have over 100K miles on them.

Than the bedding in is even more important. Generally, we bed in new rotors with used pads (of the same material). But sometimes you can't do that so you just have to warm everything gradually, you'll still be OK with the procedure above. the "abrasive braking" on the lower speed applications will start to put a layer of pad material on the discs and the higher applications will help season the new rotors. What you do want to do is keep the adherent even on the new rotors, so after the final high speed application, it's important that you try and not use the brakes much until they cool down. You definately don't want to keep the brakes applied at a stop light or have to use them hard to slow down to get into your driveway. If you have the hot brakes applied for a minute (like at a stoplight) you can screw up the thickness of the adherent layer causing the "warped rotor myth". So, if you can coast into your driveway with a light application to just stop the car, you're good. And driving at lower speed (40) with no braking will also cool the rotors down. And with new rotors, it's important to move the car a foot or so (to move the pad to disc location) while the brakes are cooling down. While this all sounds pretty intensive, the benifits in smooth rotors and properly bedded pads are worth it. Side Note: If you have the pads on for a while doing normal everyday driving and plan a track day, on the way to the track, rebed the pads in. With the brakes warmed up to "normal", do a couple hard higher stops if you can, then drive for a few miles without touching the brakes. this will smooth out the adherent layer some and bring the brake power back somewhat. |

If there is no ridge on those rotors USE THEM!!!!! New rotors are not as good as older rotors. I've seen my c5 buddies at the track change rotors a lot. Me I'm still on 4 yr old rotors. Where are you going for your track day? That will tell the tale if the HPS will work. |

Hi Jim,
I will be going to Atlanta Motorsports Park, the new track just outside of Dawsonville. I have been doing volunteer work for them and have 4 free track days to use this year. It is still under construction, but will be having their first sessions in early March and will be fully functional by April/May. Looks like a well laid out track with a lot of elevation changes and about 1/2 mile longer than Road Atlanta. How is your engine build coming along? |

You are going to want at least HP+ all around for that track. Maybe even a DTC compound on the front. Engine is comming along. I should have the valves and other parts needed to finish the first round of machine work (clean block, replace bent valves in the head, and replace freezeplugs and cam bearings.) Calling around this week for the polish crank and balance work. Ordering the cam and oil pan. should have it together before mid-March and in by the end of March. |

I've seen the track map so many times I can almost draw it with my eyes closed. Talked with Jeremy several times over the last few years. Last time I was at the location it was just a mud track.
Based on the elevation changes, expected speeds and number of braking zones before sharper turns it won't be brake eating like CMP, but you will need really good pads to brake from 110+ to 45 for a couple of turns. HPS just aren't made to take that kind of heat. The long straight you are going to be near top speed of your car right before you have to brake heavy for the turn. Thats going to happen 15 times or more in a 30 min session. There is enough braking in the rest of the lap that if you don't boil the brake fluid the HPS will fade real bad. I've been in a c6 at VIR, HPS pads and by lap 3 he had to break real early for the left at the end of the long back straight. By lap 4 I had him going 50% hoping the pads would come back that session. If I have a student tell me he is on HPS pads we do NOT get to 70% until the next to last session on the second day at any of the tarks I've been to. The HP+ are a little better and I'll get a student to max them out by day two of an event. HPS for the street - no problem, wife has a couple of years on hers and they are barely worn. I'm hoping to get on AMP in April or May depending on which group gets out there that needs an instructor. |

I went with slotted (not drilled) rotors from Ebay (from Hawks, no relation to Hawk brake pads) and they work great for me. I can't stress enough what was said above, BED THEM IN! This is a must. I only bedded mine in once, when I installed them, and they are fine still.

My, Bill... that track has some pretty nasty runoff zones... I mean... bulldozers and shit.
As for rotors, I did Powerslot Cryo treated. They are holding up very well. I got mine from Tire Rack. Which is a sponsoring vendor! Click the Tire Rack picture on the left nav and order away! I also got my pads from them. NAPA rotors are VERY good. And a good price. Check Rock Auto for rotors, too. Remember, there is a 5% discount code over in Corvette Chat! |

The track is coming together, but still a lot to be done. It has some very steep terrain and the amount of underground storm water piping, catch ponds, etc is just amazing. As is the $$$ in the ground and grading before they even started on the track itself. Jeremy said the main track paving is 100% as of today, the cart track about 50% and the parking and garage area paving is maybe 10%.
But he did post my picture on facebook. |
