What is Strut Sectioning and why would I need it?
Strut sectioning means cutting out a section of the strut tube and welding it back together. This is done on a lowered car to gain back some bump travel in the suspension. Wayne Burstein wrote up a good description of this for IZCC and its reprinted below with his permission: Let’s start by defining the task at hand. We want to lower the car in order to lower the center of gravity. I’ll skip all the analysis on why we want to do this because there are lots of good books on the subject, and confine my comments to what you might run into in performing this on a Z. First I need to define a couple of terms: Bump — suspension travel in the compression direction (i.e. the result of hitting a high spot in the road). Rebound — suspension travel in the opposite direction (i.e. the result of going over a hill and the wheels leaving the ground). The first problem we run into is that when we shorten the springs, we are reducing the available bump travel in the strut cartridges by the same amount
