I’ve had both carbotech and power stops on my GS’s and you pay twice the price for carbotechs and there’s no difference from a driving perspective. If you read all the info from the US forum they are constantly killing power stops. It’s more bull due to a vender selling carbotechs and trying to kill the other brands. If it was me I’d buy powerstops at half the price. Trust me you won’t have an issue and save some money. You can buy them on amazon.ca
