Do I have standard, M-Sport upgrade or the M Performance brakes?

My car is an M-Sport, and it has the unpainted Brembos....so im assuming the M-Sport upgrade? im looking to replaced to rotors to drilled/slotted.

You have standard, if they are unpainted and single piston in the back (M Sport would be blue and dual piston in the black).

Your front calipers are the same as those who opt for the M-Sport Brakes or the M-Performance Brakes. Your rotors are not the same size however (~345mm vs 370mm)

Your fronts could be either 340x30 or 370x30 depending on year and options. Grey will likely be the 340,s. The larger disc will be paired with the 2 piston rears as noted above. I have read the caliper for the 370 rotor has a slightly different bridge than the virtually identical 4 piston one designed for the 340 rotor. I have never actually confirmed this.
Best to measure the diameter of your existing rotors with a tape measure The difference in diameter is about an inch and should be readily obvious with a tape measure. or even better check the rotor part number on the hub against info on the turner motorsports website re brake system differences.
