Q: Does the carbon ceramic BBK fit factory 19-inch Tesla wheels?

Yes. Despite the jump to 6-piston calipers and 394mm rotors, the kit is engineered to clear factory 19-inch wheels, and it is designed around Tesla’s 19-inch Tempest and 21-inch Arachnid wheels plus all Unplugged Performance wheels and effectively any aftermarket 19-inch-or-larger wheel we have seen. Keeping 19-inch compatibility matters for drag and range setups where a smaller, lighter wheel and tire is an advantage.
