The Ford Focus ST250 EBC Yellow Stuff Pads are designed to work with a performance disc such as the Powerbrake RS Series discs or the EBC GD Series discs. The Yellow stuff pads drastically improve braking performance and can withstand a higher heat range and won’t fade like the OEM system under hard driving. This pad is not suitable with the OEM disc/rotor.
The yellow stuff pads are suitable for road and short track events. These brake pads for your Focus ST250 are an all-around pad which offers good bite when cold and will still perform at high temperatures.
