NA I disagree.
I've heard more times than not shocks wearing out on lowering springs
Also the springs are stiffer but with the springs siting 30mm lower to start with, they are causing travel on a part or the damper that's not designed to always be travelling.
The m3 suspension isn't identical- not sure why you reckon it would be but it's a coilovers setup like ours so although the same components will not be 'shaved off' we will have similar components that build up the space.
