I've got a big brake upgrade on the front and the DNA disc covers on the rear. But the 360 wheels are quite an open design and you can easily see that there is not much meat on what is meant to be the disc so I decided to add some "meat". I wanted to add some thickness so I needed something light and easy to work and bond. I bought some nylon 10.00mm chopping boards which I then made into sections that I could work to the correct shape plus drill holes in to match the disc cover. I have added some photos so you can see the process.
