Looking for new pad suggestions.
 

At my last track day I noticed some smearing of pad compound on the rotors, and they were smoking after a couple sessions. I didn't get serious pad fade, but they definitely lost some bite. Now I'm looking for another pad that'll take a bit more heat, but have similar initial bite and pedal feel as what I currently have.

I'm currently running Ferodo DS2500's and have zero complaints, just need more heat capacity now. Does anyone have suggestions for what will feel the same (or similar)?

I'm considering Carbotech XP8's, something in the Winmax range or Ferodo DS3500's, but am totally open to suggestions.

The car is primarily a street car, and does see a lot of street miles (I'm at just over 65k km's, took delivery mid July 2012). I'd prefer to not be swapping pads, but if there aren't any daily tolerable pads that'll take the heat then I'll have to consider that.

I'm also not running any ducting yet (it's on the to-do list, but I'm a slacker), would a good ducting solution (touge factory) drop temps enough to keep the 2500's happy?

It's time to graduate to a race pad.

I'd recommend Carbotech XP10, or Project Mu Club Racers. Both of these pads are proven to make minimal noise, once properly bedded in.

You'll have a similar experience to your DS2500 with other "hybrid" pads.

How's the feel and bite on the XP10's or club racers? Ideally I want something that is very similar in bite and pedal feel.

Take a look at the CL RC5+ pads. They're sintered pads much like the ones found on sportbikes. I had them on all 4 corners of my old DD/AutoX/Track NC MX5. They are absolutely THE BEST pads I've ever had on any car. They provide the same stopping power in the dry and and wet. Worked amazingly in freezing temps as well. Stopping power is akin to having a BBK, without having a BBK. Pedal feel is firm and easy to modulate. Maximum operating temp is above 1800 F. I don't believe I've ever reached that. You'll have to run racing brake fluids. And despite the incredibly high temperatures, I have never boiled my brake fluid. I have never had any hint of fade. Ever. Initial bite is similar to stock pads, and progressively and predictably provides more stopping power as you push the pedal harder. Getting it to temps is easy and takes absolutely no time. 2 or 3 hard stops from 40-60 MPH will get them to near ideal operating temps. And the fronts lasted me a good 25,000 miles. The rears were still above half. And absolutely no bedding in required.

Cons:
Price. But for a dual duty track/street pad, I couldn't imagine anything better for the price.

Dust. Can be a little dusty on street and track use. I just said F it and stopped washing my wheels.

Noise. It doesn't squeal as bad as semi-metallic pads. When it does, it actually isn't too bad. The only times it really squealed on me were when it was really cold outside and when the pads were low. Also, since it's essentially a full metallic pad, it shrinks a little when cold. You may hear some thunk noises coming from the brakes until you get it up to temps when it expands and the thunking noise disappears.

Rotor wear. Since it is a full metallic pad, there will be a little more rotor wear than other pads. In 25,000 miles of use, the pads ate through about 1.5-2MM of rotor surface on the fronts.

Heat radiation. The pads get the brake system hot. You can feel the heat radiating from the wheel well after hard runs.

I suggest looking in to these pads. There are even more hardcore pads such as the RC6 full race and RC6E endurance pads.

I plan on putting a set of front and rears on my BRZ in the near future.

I run PMu 999 cant be happier

Previously we used Ferodo. Now CL-5+ for daily driver and track days.

Races we use CL-6 but very noisy

All race pads will have substantially more bite, and also respond more to modulation (more sensitivity).

Going from street pads to race pads is a one way street... once you drive on race pads, you won't want to drive on street pads.

I daily drive on Project Mu 999.

I wonder if the Ferodo DS1.11 isn't the pad you're looking for, assuming it's tolerable under DD conditions; pads from the same manufacturer frequently have similar bite & release characteristics:

Definitely time to schedule that.

That's an enduro pad... I wouldn't recommend it for street use at all. Within Ferodo, DS3000 or DSUNO would be a better match.

I could never pull that off or I would do the same. After mowing through 7 different pad option, including the DS2500s and DSUno. I have to run a dedicated street pad and track pad. My favorite combo has become the Carbotech 1521s for street and PMU999 for track by a large margin.

You can actually get heat in the 1521s for situation like autox, or panic stops on street.

Is there a way to understand that just by looking at the chart (e.g., the high Mu at low temps)? The data make the 3000 & UNO look like they would be very similar on the track - is this the case?

Unfortunately not; you'd have to dig a big deeper into the compound and metalurgy.

Feel free to mention me in any post with a @CSG Mike. If I don't know off the top of my head, I can probably get the research done for you, and so that I can answer future questions for other people :thumbsup:

Playtex?

Oh shit, wrong forum and wrong kind..

What are you even doing on those forums in the first place?

Stuff for friends..

Will do, and thank you!

I should've been more specific about the feel/bite... I'm ok with it being firmer and more bite, I just don't want to go back the other direction.

How are the 999's compared to the club racers?

I run PMu 999's from @CounterSpace Garage and CL RC6E from @JRitt.

Love both sets and both are pretty comparable in all regards. Both have excellent release characteristics, work well across a broad temp range (consistent behavior), work well at very high temps, good initial bite (but not crazy). Both dust as much as you'd expect them to.

I haven't used the club racers.

Slightly increased initial bite, larger modulation range, higher temperature capacity (although it's not stated on paper), and much less mu drop off at high temps.

380hp s2k, stock sized brakes front/rear, 999 front/rear with Torque RT700 (David's car). The car is street driven with 999 as well.

I'm on the cl rc5+ f/r and ap sprint kit.

Loving them as a lazy mans pad, occasionally a bit noisy with street driving but fantastic when cold/wet. First week I put on it ended up consistently in the 40s and rainy. Never an issue with initial bite. The pedal feel and bite is giggle inducing.

Did an hpde last week, only a touch of pmu fluid had changed color when bleeding. Fantastic braking power at all points of every session.

Downsides: dusty, and expensive.

Just looked at the price difference between the club racers and 999's, yikes :D The 999's sound good, but are a bit out of the budget for this year.

Adding my two newbie cents in here, I ran the Winmax W4 at the track last week and had zero issues. Plenty of stopping power for my skill level.

They are still on the car for street duty and aren't noisy at all. I'm planning another track day in July where I will hopefully push them harder.

how are the 999's on the discs?

Similar to any other sintered metal pad. With your application, you'll probably swap disks from heat checking/microfracturing getting to a scary level, rather than the disks too thin.


Shameless self promotion: CSG carries every pad mentioned in this thread. Every, single one.

What's your shipping to Canada like? Will you send USPS (or really, anything other than UPS)?

For our Canadian brethren, we ship USPS to help you guys out. Always specify through e-mail or PM so we can make sure it gets shipped properly. ;)

We can ship USPS.

Please keep in mind that USPS flat rate boxes have a 20lb limit (enough for about ~3-5 sets of front pads, or 2-3 full sets of front/rear pads, depending on what pad and caliper it's for)

I don't see CL RC5+ pads for the Twins.

PM us; our website is only a fraction of what we actually distribute.

I dithered a bit, and went with a set of Winmax 4s (F/R) on advice from CSG--jumped on the group buy.

I'm on the stock rotors, no cooling, but did flush the system with Motoul RBF 600 (Torque 700 was not available). I've done one open track day with these pads: ambient temps around 75-80 F; track temps around 110-115 F by mid-afternoon. The track was Thunderbolt at NJMSP; a 2.25 mile point-and-shoot style track with several very hard braking zones and not much opportunity for cooling between turns. The event was 7 25 minute sessions. I ran every session; max speed was 115 on the long front straight with a braking zone to about 70-75 mph for turn 1 (should be faster, but hey, it's my street car!).

Car is stock except for a tune and some exhaust. I ran 1/2 the sessions on the stock wheels / tires just to see what that's like, and the rest on Michelin PSS2s.

Long story short, zero fade and great modulation everywhere, all day. Enough grip to activate ABS (traction control was always OFF; no pedal dance). Dusting is very moderate and I keep the pad in as my full-time pad everyday / everywhere pad. Moderate squeaking when hot; always bites and works well no matter the temps, rain, or whatever.

I'm primarily a PFC guy, and try to use their compounds almost exclusively on my race car. But this particular Winmax compound is a very nice "compromise" pad that works well in many environments.

I'd by these again and will use them on track again. I also have a set of Ferodo 2500s to try at some point.

BTW, CSG rocks when it comes to customer service.

Hope this helps.
