The DH is Ford's attempt to maximize profits on the Mustang. If they can establish a performance variant that doesn't require them to pay Shelby a licensing agreement, there is more profit in it for them.
I can confirm there are different windshields based on your model. I had to replace mine(rock) and the dealership needed my VIN to ensure I got the correct glass.
If your dealer tries to void your warranty over springs, find a new dealer. If it is that much of a concern, just buy FP springs and have the dealer install them.
I'm saying that the dealer's sell rate has at least 1% baked into it. I know this isn't YSP, but it effectively is the same thing. That number will only increase when they can no longer make money through "BS" fees. Most finance guys prefer fees as it is "upfront" cash for them. Baking that...

Tied selling is a federal crime. The FTC oversees the prosecution of it on the federal level. Your state's AG will bring charges on a state level. Tell the dealer you want a copy of the sales agreement to file with your state AG. They will change their tune quickly.
