Thanks for you concern Mickmate.
Below is a different shot of the adjustable brackets. These are designed to use 4x 0.375in bolts. The brackets are 0.25in steel (most kits use 0.1875in). With other words, before this bracket fails the 0.5in shock bolt fails.
Now to the reason of the adjustment, the coil over shock has no ride height adjustment by itself. What is adjustable is the stiffness of the spring, which translate how tall the shock is compressed under the weight.
So, if you want a lower ride height you need to "soften" your car. These brackets allow to choose the correct firmness of the car and independent to the position of the frame to the surface.
