C2 is available in stock. :)

I just ran CSG Spec C2 for the first time (only at the front, with Winmax W5 rears) at Palmer this past Sunday. I ran them with Conti ECS street tires and with Hoosier A7s and honestly they were great at the track with either, which in retrospect is kinda surprising given the radical difference in tire grip (A7 5 seconds faster). I found the pads to be very linear and predictable throughout ~15-20 minute sessions. Plenty of bite but not too initially-grabby, which makes me feel more comfortable about the possibility of disconnecting ABS to save a classification point and drop another 42 lb. for Watkins Glen next month... Won my time trial class at Palmer, COMSCC T60 (9 competitors including a 981 Cayman S) with a 1:48.16 :D

They're also fine on the street, they work when cold, not too noisy and not too dusty either. Pretty remarkable!

Installed C2 pads front on AP Sprint and C1 rears for OEM calipers.

Running for about a month for street and canyon/HPDE.

Pads bedded nicely and very linear feel on the pedal. Not generating enough long term temps to know if they fade but very happy with them.

Slightly noisy for daily driving but better then the CL6 sintered for sure.

Nice pad

Installed C2 compound on AP Sprint front OEM rear. 3 track days on them so far. 1 at a track with some pretty heavy braking zones, 3 100 to 40ish mph.

Very good initial bite with good modulation throughout, was worried they might be an on/off switch like some aggressive pads. Didn't have any fade in multiple 20 minute session. Will need to run more events to comment on longevity but seem to be holding up well so far.

Overall, very impressed with them, and glad I bought some.

staples323: on what tires (model/width)?

Thanks, I forgot to add that. Original post has been edited with tire info.

Who has tested the spec compound spec cp?

Hundreds (thousands?) of folks.

What do you want to know?

I have seen the data on the website and I like them, but I am afraid that they will not work well on the track.

My setup is Brembo GT CSG in front with PBS Pro Race and DBA T2 discs. Oem with cosworth pads rear. It has always worked very well for me, I do some trackday a year looking for the best times with Nankang AR1 225/45/17 and some fast laps in Nurburgring.

The car is used on the road and I do not like the infernal noise that the brakes make sometimes, so I have thought of CSG Spec CP in addition to the good comments of other compounds CSG SPEC

I have the CP with AP 9660 calipers. I didn't like them on track. I'll post more detail soon.

After further discussion and some digging, Pat is on the SP1, not the CP, as that is what his shop ultimately ordered.

The SP1 is a true street pad designed for low dust and noise on race calipers, and intended for those who street drive their race setups with the intention of swapping to a CSG race compound at the track.

It's a testament to the capacity of the AP 9660 kit that a pad that was NEVER meant for track use survived track use with a veteran driver at the wheel.

I don't even see SP1 as an offering. What am I missing here?

Only a guess, but maybe he meant Sprint C1?

No, they have offerings not listed on the site. It was an SP1.

The compounds listed are the ones that are plug and play, easy for anyone to use with little to no additional guidance.

There are many, many other compounds prescribed on a case by case basis, based on conversations with the person, shop, team, and car involved.

For example, the 86/BRZ has a digressive, linear, and progressive option for sprint compounds, one high performance street compound, and one endurance compound listed. There's many others that are only offered when a user has a specific characteristic they're looking for, or a specific brake behavior they desire, or perhaps have a unique need due to their aero package, etc.

Here's an example. The 5 fastest circuit supras in the world all run CSG. All 5 run a different setup. While the listed Supra compounds are similar to the BRZ, none of the 5 supras run any of the list compounds, as their brake setups have all been optimized around the data and feedback provided.

Neat.

Any recommendations for my setup?

You'll want to email CSG with your setup and use case, for a recommendation. I have no idea what your setup is or what you do with the car, so any recommendation I make is just a blind shot in the dark.

I had put it above😅

Ah, apologies. I reply to hundreds of messages/emails a day, and don't look for context unless clued in!

For your setup, CP front and rear would get the job done without issue, and also be pretty quiet.

The only caveat will be that you will want to FULLY cool your brakes down after each lap before parking, so that you do not get unwanted brake deposits from the pad sticking to the rotor, as the CP is ultimately a supremely capable street pad. It doesn't like being parked hot.

Thank you very much, I had no idea of that characteristic, I will try them next year

I checked my CSG CP pads on stock sliders after about 2 years of dd and autocross. I have just under 20k miles on these pads.

The material left is between 9.5-10mm because of slight pad taper. They have always had a slight bit of noise likely because I put them on stock rotors that had been run for 6k miles.

@dragoontwo two those look basically new!

If you say so. What is the new thickness supposed to be for the CP on the stock calipers?

18mm front 17mm rear, including the backing plate.
