From the 2009 GCR

5.b.1 Springs and Shock Absorbers
1. Shock absorbers may be replaced provided that the replacements (a) attach to the original mounting points, and (b) are of a non-remote-reservoir design. The number and type …………

In my mind the only questions is what would be considered the original mounting point as reference in the GCR. Looking for the definition of “original mounting point” in the glossary turns up no new information.

They do define Pickup point
Pickup point (Suspension) – The location of attachment of a suspension component on the frame or structure of the car. Pickup point is also referred to as “pivot axis.”

They do define Attachment Point
Attachment Points (Suspension) - The locations at which the fixed and moving ends of a shock absorber are mounted and/or the location of the suspension component on the frame or structure of a car.

In both cases above they indicate it is the frame or structure of the car. Would the same definition be used for Mounting point? I don’t know.

They do say that you can replace this part in a Macpherson strut equipped car but for those of us with a different suspension design it does not seem clear.

Just rambling…….
