I'm really curious about this. I suspect many of us ride around on shocks that are past their prime and we just don't notice. When faced with replacement - often because they have started to leak in my case - we're told to go with the 'good stuff' in the aftermarket world and face a $1700 tab...or even more..to replace and upgrade two shocks.
A set of two shocks and two struts for my BMW cage can be done for $400 installed! And the OE stuff on my car will easily last 100,000 miles.
Can anyone shed light on this?
