I only ask because you posted that the wheels are slippery on lexan but not on carpet, while the brake pads are grippy on both, and I had thought that the material on your brakes appeared to be the same material as the tread on your wheels.

From the testing I did, roughtop tread had a reasonable CoEF on the bridge, so part of me wants to say the reason you found you were sliding off the bridge before adding brakes wasn't because of the tread's CoEF, but because of the fact that your drivetrain PWMs were probably in coast mode, and you simply rolled off the bridge (your CIMs were backdriving).

Of course, I definitely could be wrong. I'd love an official 175 answer.
Official 175 answer:
"It's top secret."

The PWMs are in fact in coast mode.

The tread used on the brakes is black roughtop that we've used for tread in past seasons. The material is a little harder than what is currently on the wheels.
