I had the HP+ onthe '99 and still run them on the '03. Both with 225/45 Rival/S and Bilstein coilovers. They squeak horribly on both cars. Performance and feel are meh- strett and track. Running performance friction (01 compund I believe) on the 99 now and they are a far superior pad- especially on the track, but even on the street. I would never again buy HP+. PF should start making pads for the spots rotors- I ink there would be quite a market.

Guess i should check my Yellowstuffs. Besides tearing up rotors and being noisy, dusty, and horrific at cold stops.... i like 'em well enough.

If there's meat on them, i'll see if i can echo the sentiments after upcoming track day.

~2200lb NB w/ driver

That sounds like quite the endorsement for Yellowstuff haha. "They kinda suck all round', but i like them."


The PFC pads seem like a winner, good for the track, usable on the street, non corrosive, no transfer layer needed, however they dont fit sport brakes which I'm kinda stuck with for now. The HP+ pads seem to always be middle of the road, some say its decent, others that its complete garbage. Right now I think the HP+ and maybe stoptechs are the only viable options.

I agree with sixshooter. You can run StopTech or HP+ pads on true 200 treadwire tires and above on stock power. Use an inside shim and good fluid, and they won't fade. I have done it several times. HP+ has more initial bite, if that is what you are after. That comes at a cost of sounding like a school bus had an alien love child with a fog horn after they have been heat cycled a few times.

Swanpuppy

Now THIS sounds appealing.

HP+ does whistle a bit on some cars. PFCs don't seem to have that issue.

If you think the HP+ whistles, wait until you hear the R8s.

Steve Dallas

I think it varies with the weight of the car / surface area of the pads / amount of heat put into them. People report the whole gamut of experiences with them.

I ran through 4 or 5 sets of HP+ on my RX-8 about 5 years ago. After one track day, a new set of pads would whistle at track speeds and howl terribly on the street. I could quiet them down a bit by burnishing the pad surfaces and cleaning and re-greasing everything, but they were still embarrassing. People would actually roll down their windows to helpfully tell me I needed a brake job. I found DTC-30s to be better, more linear performers on the track and quieter on the street, so I switched to those, before discovering Carbotech. Hawk's Street/Race pad is supposedly the DTC-30 compound with bevels and shims, so that may be an option. I used one set of them (all I could get and was in a rush) and found them to be extremely similar to DTC-30s.

Having said that, there are plenty of people who run HP+ at my home track, and they report tolerable noise on the street.

I have a set of StopTech Sport pads on my RX-8 right now as my street pads. They did fine for me on a track day with Star Specs. They do not have the initial bite of HP+, and they dust more, but they are quieter, and the dust is not as corrosive.

Swanpuppy

Non corrosive dust is something I am looking for. Glad to hear the stoptech's were able to handle some lapping, not a lot of reviews of those.

My experience with stoptech:

N/A car, noob driver: great on track.
Turbo car, more experienced driver, PIR (hard on brakes): they literally fell off the backing plate when I removed them.

Good to hear. I have done ONE HPDE event, and autocross, car is stock except for DIY billies and new sticky summer tires (federal 595RS-RR). Adding power is quite aways out. StopTechs are very tempting due to price. I think a full set front and rears were under $100 (compared to almost $200 for HP+), if they can handle some noob lapping thats the way to go for me. I spent the last 3 years slowly buying safety gear, I want to start spending money on actually driving.

Steve Dallas

Yep. That's about what I would expect to see.

I have zero experience with those tires, but a quick search indicates they are a "200TW" tire in the same way the RE-71R is a "200TW" tire: closer to 140TW or 120TW in real life. If so, that is a LOT of tire for a newb. We normally recommend someone start tracking on a true 200TW tire or above. You learn a lot more on tires with less grip, that give you a lot of feedback, and that don't cover your mistakes. And, the more or less stock suspensions we see on most newb's cars are much better suited to higher TW tires.

Agree regarding non-stick tires for learning.

Great data point for me. Changes the plan for my next event.

Thanks much,

I suppose I should follow up on this thread since it's been revived -- I have a couple track days on the DTC60s, and have been running HPS on the street. No issues with fade or overheating with the DTC's and the HPS pads work well enough on the street. I wash my car after any track day anyway so the corrosive dust hasn't seemed to be an issue yet. Here's an example lap at Road Atlanta right after I got the DTC60's. I'm pretty hard on the brakes generally (ran up someone's rear bumper this lap, but usually brake hard in the latter half between 1 and 2 marker of turn 10). I'm not sure how they'd handle DOT slicks, but for street tires they're fine. It was 95 degrees in Atlanta when the below video was taken.

Put on some pants. You should consider wearing more fire protective clothing in general. I know it's hot.

As for the driving, I'd say you are slowing too much going into turn one. You should be going fast enough to need to go all the way to the track out strips. It will help you to have more speed to climb that giant hill as well. It also appeared that you departed turn 4 and started to turn right for the esses a little early which makes them a little less straight and can slow you down a touch.

I'm no expert at RA, and T1 and T12 scare the eff out of me sometimes, but it is a monumental track to drive.

Morello

Pants: Definitely - I had been switching between pants and shorts (as mentioned, 95 degrees in Atlanta is miserable) but forgot on the last session of the day. Definitely not good and I didn't realize until I got out after the session was over and saw my pants sitting on my pile of stuff in the pits.
Turn 1 - That's about fast as I'm comfortable taking a car I need to drive home! See the first clip in Turn 4 - Yep, probably a little bit of time to be had there, though I'm full throttle through the esses anyway so probably not much.
It's a great track. I'm not fast enough for T12 to scare me yet (my right foot is planted from 10B to 1) but once the turbo is finished it will be much more interesting.

I remember the naturally aspirated 10b to 1 throttle press and hold drill. Once you add a turbo you will need to lift.

I don't have exactly what I wrote in my online info request, but I admitted that I knew PFC 11s for the Sport front calipers were not currently offered. I asked what it would take to get some made. I believe I stated, don't tell me it can't be done, tell me what it would take to get it done. Justin from Performance Friction answered my query the next day by stating "Thanks for reaching out and I hate to report that we don’t have those pads in stock any longer". That was on 25 April. I thanked him for his quick response and again admitted I knew they weren't currently offered. I asked him what level of commitment--how many pieces and how much money--it would take for them to make some. I said I thought they could sell quite a few. I have received no further responses.

Another vote for StopTech SPORT

I ran them on street and track. Took 2 days at Laguna last year without any issues on 15x9 200tw tires (Hankook RS-3), also used them for autocross. They dust more than stock, but that's kind of expected and not too bad really. Were quiet for me on the street and did their job in stock powered car at the track. They do need some higher temps to be most effective, but still usable on the street.
