The caliper will be the same but the piston sizes probably will not. It is the same ST-60 caliper but Stoptech has a lot of variations on piston size combinations depending on the application. If you can manage to find out which combination they are using and what other cars that applies to, then you can get the same rear kit and have a fully balanced kit. I'm not sure how much money you will save in the end though.
