So I found out I have 340mm 4 piston front calipers.....even more confused now

I was under the assumption that I had the following since I have a 2016 328i M Sport but the $650 M Sport Brake upgrade was not on my car/on the MSRP sticker. So I referenced the chart from Turner Motorsports chart that I've seen referenced here a lot. My car has gray calipers. This is what I read on the Turner Motorsports site:

Single piston calipers are the traditional brake caliper design on BMWs. They will be a grey/unfinished color.

F30 328i/328iX, F32 428i/428iX Stock Brakes
Front: 312mm rotors, single-piston grey caliper
Rear: 300mm rotors, single-piston grey caliper

M Sport Trim Package (code P337A)
Front: 330mm rotors, single-piston grey caliper
Rear: 300mm rotors, single-piston grey caliper

If you ordered your 328i/428i with the $3,400 M Sport trim package (M Sport aerodynamic package, 18" wheels, M steering wheel, Shadowline trim) you also got a modest brake upgrade at the same time. The front rotors increased from 312mm to 330mm. The rotors are a blank design, not dimpled/slotted. The stock single piston calipers remained but use a different bracket. The pads are slightly more aggressive than the stock parts. Note that there was another M Sport Brakes upgrade option that had Brembo calipers from the 335i (see below).

I assumed that info was correct but I wanted to triple check with the parts dept at my local dealer where I purchased the car from and from my BMW independent tuning/repair shop. They both came back with this information after I gave them my VIN:

FRONT ROTORS 340MM 4 PISTON
REAR 330MM SINGLE PISTON

So is there yet another option that isn't referenced that my car has??? Again, my car is a 2016 328i M Sport WITHOUT the optional M Sport brakes that have blue calipers.

Well, my car had the S102A option which is the "reinforced" or "heavy duty brakes", which is the 340MM 4 pot fronts. I believe that's what you have as well.

Read turner's 335i page, not 328i. You have stock 335i setup.

Weird, since I have a 328i. I'll take it though.
