At the ripe old age of 17-miles (aka still brand new) the dust boot on the RX7's idler arm has split. It was barely hanging on when I noticed it after going for the first drive of the year (which was also the first on this boot).

Note how it has split completely down the right side

Warranty time. I’m not taking this arm off (and rendering the car inoperable) until I have the replacement, which I’m really not looking forward to changing out. Again.
