You would need a custom mounting bracket unless they happen to he the same fitment (unlikely). There are multiple BBKs for the CX5 out there
CYKA being one. You can get true bbk, front and rear with floating caliper if desired.
You'd have a better chance of swapping the CX5 Turbo's bigger front brakes. But instead I'd be looking at performance rotors (slotted and/or drilled, vented) and pads before going nuts transplanting calipers.
The problem could be from calipers or disk (( The car has 68000 km and every time when I`m using brake, the steering wheel has vibrations
I said to make an upgrade with some oem parts from other cars (In Europe is very easy to buy SH calipers from Porsche or Audi )
bigger brakes are rarely needed on modern cars - there are 2 issues involved: heat capacity & brake torque
if you can lock the wheels and skid the tires then you have plenty of brake torque
if you race your cx5 you MAY need more heat capacity; rarely this can be an issue lon very long mtn. passes (descent) - for either the first thing to do is to duct in air to the F. rotors; often an owner has not replaced the brake fluid every 2 years (or every race) or has used an inferior product
anyway, use a dial indicator to measure run out on your rotors
