What happens here

Before installing the new coil springs, drill a 5/16-inch pilot hole into the bump stop mount. Next, use the provided self-tapping bolt to create threads in this pilot hole. This bolt is specifically designed to cut its own threads, making it easy to secure the bump stop extension. This step is crucial and often overlooked, leading to having to remove already installed coil springs later.

Goal: Install the bump stop extensions to prevent over-compression of the new, taller springs.

What they say

Yep. I'm just going to drill a 5/16 hole in the bottom here. And then they actually send you a bolt that selftaps. That's what cuts the threads for the bolt. What is the point of that bolt? This is that selftapping that cuts the threads for the bolts when we bolt that uh bump stop extension down. Okay. So, even though you did one
