Yes, but that means you can not move the front caliper to the back as the other poster mentioned earlier up. You need a rear-specific caliper as the existing one is a front-specific caliper.

I really hope they are using a M3-specific caliper application as opposed to using a universal sized piston caliper with adapters to fit the M3. The brake proportioning will be way off.
