What Concave Back-Drilling Actually Means
"Concave back-drilling" shows up throughout our site, and it's worth explaining exactly what it means instead of just repeating it as a slogan.
The problem with a flat drilling pattern
A generic mounting pattern drilled flat doesn't account for the actual curve of a crash bar or the pod itself. That mismatch shows up as a gap, a wobble, or a pod that sits slightly off-angle once it's tightened down.
What concave drilling does differently
We drill our own pattern to follow the actual curvature of the mount and the pod housing - concave instead of flat. The pod seats flush against the surface it's mounted to, with full contact instead of a few high points bearing all the load.
Why it matters at speed
A pod that sits flush and fully seated doesn't work loose from vibration the way a pod resting on a few contact points will over months of highway miles. It's a small detail in the moment of installation and a big one two years down the road.
