Mix: SH Performance coating with ABE - fully metallic sintered coating - very good braking performance - can be used on all steel discs - only in exchange for sintered coatings as original equipment - can only be used to a limited extent in racing, as there is no heat resistance from 400 degrees Celsius. You can use used oil or please personally return to us the oil filters and all oily waste that occurs during oil changes. Alternatively, you can choose to have the item shipped by post if you bear the shipping costs. Please make sure that the used oil is labelled as hazardous goods when it is sent.
