The shock absorber simply dampens the spring's rebound - the spring takes the weight, so for the same pothole, a 180lb spring on a GTE will deflect further than a 180lb spring on an SS1. To make the two examples rebound at the same frequency the GTE damper would need to be set harder - that's nothing to do with the spring dia but the vehicle's weight, the amount of deflection and the spring's "poundage" (which is composition, wire dia and number of coils).

not sure - you said "why go to a 2.25" on the 5a" then started comparing it to the weight of a small sports which is nothing to do with spring ID?

And the point I'm making is that the actual damper is more often than not, the same - the difference depends on which spring seats are screwed onto the external thread.

Useful info from another thread added for posterity:
Does anyone know what the correct distance between the eyes/mountings on a car riding at the correct height is

13.64 inches (346.4 mm)



Handy info if you want to make a solid replacement for the dampers to check camber and castor angles without spring/ dampers fitted (or to check your current setup for possible ride height issues).

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.
