Black, Yes they are much "healthier" than the standard Crossfire.
Size wise once you've seen them side by side you'll never mistake standards for SRT. If you can take a tape with you and do a rough messurement.
13.5" SRT fronts.
Also the rear SRT brakes are a dual vented disk. I think the standard Crossfire has an unvented rear.
If the rear disks look the size of a Grapefruit, would scare you to put your life in their hands they are the Standard.
