BBK pad advice for hard track use
I've heard good things about Carbone Lorraine pads but no experience of them.

BBK pad advice for hard track use
Thanks, I’ll ask them if they make XP24 pads for my rear BBK.ph001 wrote: ↑Wed Sep 25, 2019 3:36 pm Carbotech pads are superb albeit quite dusty. The XP8 is similar performance to the Performance Friction Carbon Metallic .11 compound but the latter give off far less dust and are about half the price!
The Carbotech range does go quite a lot above the XP8 though. See here... http://www.carbotech-europe.com/compoundstechnical.html
I’m going to contact Tom’s BTCC source for front pads and I’ll try running them variously with Pagids or these at the rear.

Hi John, good to hear from you. I’ve read good things too but I need to look into whether that’s from people using them for fast road and light track use or in a dedicated track car.

I'm sure they're excellent but they sound like a type of quiche.

As an interesting coincidence, the friction surface of my pads looked a little like burned quiche after my last track day

I'm not too convinced the XP24 compound is a good choice for the rear as they need a lot of heat in them to get the coefficient of friction up and it sometimes can be hard maintaining a high temperature on the rear disks if the track isn't very twisty. They also have an extremely high initial bite which could result in some interesting underpant stains coming into fast bends. I just think you might find them a bit too inconsistent on the rear.

That’s a very good point about the aggressive initial bite. Since I’m often a little closer to complete loss of control than perhaps is wise, that might just finish me off!
Interestingly, since fitting KW Clubsports, the car has very little pitch under hard braking and the rear brakes get just as hot as the front after a few laps. The rear pads seem to wear at 1.5 - 2x the rate of the fronts too. Since I switch off DSC, I presume the wear rates reflect the relative contributions to the overall braking effort. I agree though, a less aggressive pad would be a good idea.

Hi Richard, glad you're enjoying Oz. Same with the AC Schnitzer Racing suspension on my Z4MC which highlights how bad the OEM suspension is and how the problem of pitch, roll and squat can be easily corrected to improve handling and performance.

Maybe try some OEM pads at the back and some RS29's or equivellent at the front and see how you get on.
You could also try a mild performance pad in the rear like an EBC Yellow / Bluestuff or DS2500

Might be worth checking what temps your brakes are getting too before buying any?BMWZ4MC wrote: ↑Thu Sep 26, 2019 10:13 am That’s a very good point about the aggressive initial bite. Since I’m often a little closer to complete loss of control than perhaps is wise, that might just finish me off!

I used to run EBC Blues on my track car, but if they get too hot they just crumble away - was getting 2-3 trackdays from a set on the front. Have now switched to Performance Friction PF08s and they're a lot better - have done 6 trackdays with great performance, and they're only half worn.
they do more aggressive compounds so could mix and match a bit (PF10s on the front, and 08s on the rear for example). Just throwing another name out there for you!

I’ve ordered a set each of Project Mu H21 and RayBestos ST45 pads through Tom’s contact (thanks again). He doesn’t have anything suitable for the rear callipers, so I’m planning to try them with Pagid RSL29s for the rear.
How that combination affects the balance under braking and pedal feel, will decide where I go next.

I’ve measured the temps previously with an infrared thermometer but I don’t have one at the moment. They’re readily available from eBay so I’ll get one before my next track excursion.RedUn wrote: ↑Thu Sep 26, 2019 12:56 pmMight be worth checking what temps your brakes are getting too before buying any?BMWZ4MC wrote: ↑Thu Sep 26, 2019 10:13 am That’s a very good point about the aggressive initial bite.
