Sorry, I'm old school - AFAIC, springs rates are always measured in pounds depression per inch. Even in these days of the metric system.
What is a 6kg spring?? What does that measurement mean?
Without knowing how far the thing deflects at a 6kg load, the number is meaningless to me. Makes it hard to compare to the standard spring rates or anything else, which are either expressed as pounds depression per inch, or as Volvo specs their springs, Newtons per one centimetre depression.
Anyway, from what you've said, these clowns flog kits that run the same spring rates front and rear in a 240 - and that setup is so wrong, it's laughable. Unless the buyers are fans of plow-ahead understeer transitioning to violent snap oversteer. Especially on bumps.
Or maybe the market for that junk don't like or care about going around corners quickly and with stability...
If things are done correctly, shock bump and rebound rates are valved to match the springs , the application, the tyres, and the driver's preference. My personal preference is for a fast and firm bump setting, but others may prefer a softer bump setting with the same rebound rate.
This is a great article about setting up shocks correctly on a 240.

As for the peddlers of this junk valving shocks properly? We've already seen how a set of good shocks only are three-quarters the price of this junk. Isn't going to happen. Especially not when they're specifying the same spring rates for front and back, which tells me they know not what they do.
It really depends how far and fast you want to go.
For street use, you'd be far better off with what Ash recommends than buying this Ebay junk of questionable quality. Off-the-shelf King Springs with decent shocks from Ash will give you a lot better results for a lot less hassle.
They may not have the same bling factor as the Ebay junk, but they will be cheaper, faster, and less hassle, while they will not invite defect notices, nor will they fail.
So the rear of a 200 sedan also has a pan hard bar setup, same as that in the wagon?
Yes. The layout and part numbers are
identical across all 240s (aka "cross stay", p/n 1330300-3)
