I know it's been a while, but that shudder you feel when coasting to a stop can be annoying. It could be worn brake pads or rotors, which can cause vibrations when you slow down. Sometimes, it can be the tires, too, especially if they’re unevenly worn. Have you checked those out?
Another thing to think about is the suspension or even the drivetrain. If you’ve got some play in the joints or bushings, that could also cause a little shudder. It’s a good idea to have a mechanic take a look, especially if you’re unsure.
Also, if you’re into DIY, rubber compression molding can be a neat way to help with those little vibrations. It’s something to consider if you want to tackle it yourself.
