    Looking for specific feedback RE: track day pads

    Hey everyone,Did some searching on the forum and can't seem to find specific info comparing the following for a 4pot (non-Dynamics) Scat-Powerstop Track Day pads vs-Hawk DTC60/70 pads vs-Carbotech XP10/XP12 padsFor some background, I have been using my car relatively frequently on the road course (5 days so far, 5 more planned before season's end here in Chicago). My first day out, I obliterated the stock brake system + ATE brake fluid in about 30 mins (front pads went from 7mils to the backing plate, front rotors scored beyond repair). After the first day, I replaced the brakes with Powerstop "Track Day" front (Rotors + Pads) and rear (stock rotors + upgraded pads) + Brembo HTC64 fluid. This setup seems to do a lot better (got through 4 events, 2 of them "open track" types where you can run the car for an hour straight if you want) with minimal issues (the brakes still kinda fall off at maximum attack pace longer than 20 mins). After starting the Powerstop pads around 8.5 mils, the fronts are now at 2 mils after 3 days and maybe 2.5k street miles. Since the pads are due for replacement, I figured I'd try and do some more research and perhaps try one of the other "aggressive" options for this car. I understand that the options seem to be quite a bit more limited than that for the 6 pot caliper, and even finding the appropriate part numbers for a 4 pot Scat Front/Rear pad isn't very straightforwardAny info for the above would be GREATLY appreciated!Thanks

    Can’t help you cause I’m taking your advice. I’m back to the autobahn Monday with the powerstop track pads but I’ll probably keep the rotors from z26 street package I had. I emailed powerstop, they said they have no idea why the track day folks seem to prefer the solid rotors and that it’s totally fine to run their drilled and slotted ones on the track.

    LOL Powerstops own "track day package" with rotors and pads comes with solid rotors...Not that the rotor matters too much, as long as it has decent cooling....its the aggressive pad that matters.

    Honestly doesn’t seem like there are more than a few options for us.

    Will call Carbotech in the AM and see what I can dig up, as their site isn't very informative. Anyone with any other info, it would be greatly appreciated. I am assuming I will see out at Autobahn 09/14 and 10/12 Pete?

    I’ll be out there next Monday 8/3 with a different group, mvp tracktime. Nothing else paid for yet but I’d like to do at least one more this year.

    For the Brembos there's only 3 styles of pads and typically the pattern specs will match up with the same 4 digits in the part number:
    15.4" 6-piston front: type #1405
    14.2" 4-piston front: type #1149
    13.8" 4-piston rear: type #1053

    Carbotech's site actually has a pretty good application selector to find the right pads. I usually order from KNS but direct is an option. I use the AX6 for daily driving and autocross although it is a little noisy. Track days (unfortunately none so far this year) I swap on XP12 out front and XP8 out back. There are other options out there (the race pad manufacturers can always make them following the type specs or analyzing a sample) such as the Raybestos ST-4x series, Porterfield, Pagid, Colbalt, Project Mu, et cetera.

    I chose CT pads since that's what O.G. LX road racer - and old LXF member - used to win championships a decade ago. That was Joel Vandiver (joelvan) in NASA's American Iron series with his stroked 426 Pursuit Charger then green Challenger (featured as one of the house cars to beat on the old SpeedTV show "Are You Faster Than a Redneck"). Here's a couple good articles published about him and his Mopars:

    There is also g-loc, they have a wide range of compounds. Not cheap though. Good to see there are more options.

    Thank you very much for the info!!!Ended up ordering Carbotech XP10 for the front and XP8 for the rear...they are supposed to come in tomorrow. Will continue using Brembo HTC 64 fluid. Next track day coming up soon, so I will report back!

    Though I’d share here. The drilled/slotted powerstop rotors did not hold up on the track. There’s one good crack in the rotors and a much of tiny cracks all around the holes. Good thing I brought the blanks with me to the track. I was able to swap them out before I left.

    Also, super embarrassing, ran out of fuel right as session was ending. I went out with a little over a quarter tank for a 20 minute session. Gas light never came on. I don’t think the computer works too well when you are getting 5 mpg!

    Yea that is to be expected with drilled rotors, Along with that, I've never had good experience with power stop rotors, so I stay away from them. I've been running stoptech sport rotors on my stuff now with nothing but good feedback to give. Slotted only.

    Powerstop blank rotors have held up well for me thus far. Never use drilled rotors. J Hook rotors on previous Porsches worked well also.

    You time yourself around autobahn at all? 3:05 was one of my quicker laps on Monday but the novice group was full of weird cars that really had no business being on the track creating conga lines in a lot of the sessions.
    Just curious, I feel like going under three minutes won’t be hard with my current set up.
