When to replace shocks.....

My 35i has 40,000 miles on it. It had 11,000 when I bought it 2 years ago. I have noticed the ride is a little harsher as the miles have added up, but am unsure what is a reasonable life span for a set of shocks. 40,000 seems early for a vehicle of this class, but I am about to install a set of Eibach springs and am wondering if I should do the shocks as well......

What do you all think??
 
As shocks age they usually make handling and ride softer not harsher.

In any event I’d be waiting for failure to replace.
 
Any advisories on previous mot’s? If it’s due soon I’d wait it out before pulling the trigger on anything too expensive.
 
I replaced my 23i shocks at 45k and noted the tyres grip better as the traction light came on less frequently on gravel.
The shocks that came off seemed a bit cheap made compared to the Bilsteins i fitted. Bilsteins have larger piston rod diameter, so look more robust.
Originals made some strange sqiggy noises when pushed down, Bilsteins were firm, smooth noiseless.
I compared the force required to push down on some bathroom scales and the Bilstein took more load, but on the road feel great.
 
All good thoughts. Thanks.

The Eibachs were a raffle prize, so I think I'll install them and see how the stock shocks feel. At this point, I think sway bars might happen first, but Bilstiens are on my radar.
Thanks again guys...
