I just checked and you are right. There's an SCV8 at my dealer that's been there for awhile without the dynamic package but clearly has red brembos on the photos.Aren't the red brembo brakes standard on SC? I believe it was for mine even if I didn't get the dynamic package, which I did because it's awesome.
I think you are mistaken about the brakes for the 2015 SCV8. I took delivery of mine on February 23rd of 2015. I did not order the Dynamic package because my rig is black and I actually wanted the silver accents and the 20 inch wheels. They came with the larger 20inch red brembro brakes. I believe they made them standard for all V8s in the beginning in the early part of 2015. All of the V8 inventory in the local dealers have red brakes and many of them do not have the dynamic package!
