Does anyone know the bmw part number for the rear brake sensor? Or if FCP euro carries it? Got the front from there. Need a rear. Or are they the same part front and rear?

These should be the Toyota and BMW part numbers. Looks like FCP Euro has them in stock in both BMW and third party versions

Thank you!

Anyone know the bedding steps for the project mu club racers? Been searching online but can't really find anything. Theyre paired with stock rotors.

Standard has worked for me.

80-10mph threshold braking until they start smoking, let them cool a little and repeat again for a couple more stops. Driving around without using the brakes and then park the car.

When I say threshold braking, I mean those tires are chirping and you are modulating right up to almost activating ABS. If you aren't fighting the car, you aren't braking hard enough.

Got it. That makes sense to me. I drove around a bit today but didn't do bedding this intensively. Will try to get this done tomorrow. Appreciate the advice as always.

Yeah, with the Club Racers, I feel like if you're bedding them in on the streets, definitely be more on aggressive side.
I thought I bedded them in before a trackday, but during 1st session was getting the awful juddering. Took rest of day to finally bed them in good enough.

Also club racers seem to dislike pre-existing non-CR material on the rotors. You may need to swap rotors if they won't behave after multiple rounds of bedding.

Can you explain this a little further?

Brake pads go from abrasive (cold) to adhesive (hot). Abrasive is what removes the old pad material. If you aren't aggressive enough when full cold, the new pad material will stick to the Old Pad material in an uneven way, which causes shudder.

This is why it takes multiple attempts from full cold to completely grind away the old stuff, and apply a sticky layer of new stuff. If you don't want to deal with all that hassle, just start with a new rotor.

I've been updating the spreadsheet to have tabs for brake pads and rotors for the front 374mm rotors/calipers on the Supra Final Edition. Exact same brakes/rotors that come on the ZTK package M-lites, M240i/M340i/M440i and also some 5/6/7/8 series.

Thanks for the final edition update! Does anyone know the Toyota part number for the front pads?

Does anyone have any info on the 20-25' Supra vs 26' Supra specifically w/ ZTK brakes in terms of providing any additional stopping power (60-0, 100-0)? I cant seem to find any info.

After more digging around. Car & Driver reported: 147 feet to stop from 70 mph (2026)
& 148 feet to stop from 70 mph (2020).

Pads and Tires have 10000000000% more impact on stopping distance.

Larger caliper/rotors are more for heat shedding capabilities.

Gotcha. Was just curious if it was slightly better at all. Thermal management, for sure.
