Ok measured my Springs, and here are the results. I think it's pretty clear this is a 2"+ Kit.
Front: 321.3MM
Rear: 355.6MM

Good morning California

So, springs. Your D90 would have come out of the factory with:

Front

NRC9446 (Passenger) 15.19" (38.58cm) 175lb/inch
NRC9447 (Driver) 14.80" (37.58cm) 175lb/inch

Rear

NRC9448 15.31" (38.88cm) 225lb/inch
NRC9449 14.8" (37.59cm) 225lb/inch

or

NRC9462 HD 15.25" (38.73cm) 210/240lb/inch
NRC9463 HD 14.81" (37.59cm) 210/240lb/inch

This information comes from Red90.ca - http://www.red90.ca/rovers/springinfo.html

Unfortunately Terrfirma do not give the above information, but as you can see your springs are in fact shorter than the standard OE springs that would have come fitted to your 90. To be honest looking at those numbers it is almost as if you have -1" springs...

It is more than likely that your old springs had also sagged considerably over the years so the perception of added height is also to do with that. Possibly.

The only other consideration is spring rate. This not only controls how "soft" or "hard" the spring is, compliant it is, but also how much weight the vehicle can carry/tow. NB: the two different spring rates for the rear springs. I can see that the Terrafirma standard height HD front springs have 7 coils, compared to the 7.75 coils of the OE front spring. Indicating the coil bar is a thicker diameter and a higher spring rate if the same height as the OE spring.

Which Terrafirma kit did you buy? Link?

As has been said above, the fitting of longer travel shock absorbers is not a problem for road driving and will definitely help axle flex should you leave the hard top. Just to put you at ease standard height springs can be used with standard height, +2" or even +5" shocks. The only thing to consider with the latter +5" are the replacement of upper shock mounts and spring retainers/relocators to keep the spring in position and guide it back into the upper spring mount. In the "good ol days" it was a popular and cheap mod to fit -2" upper shock mounts and standard height shocks to achieve an effective +2" extra axle droop... So do not worry if the shocks you have are "long travel", to be honest that is probably a good thing

Thank you for the help everyone. Correct I measured the Springs on the car. I can guarantee you all the car sits MUCH taller to the point it now looks funny unless I were to add larger tires which is not an option as it then will not fit in my garage.

Unfortunately, the part number I have in my invoice is not what was actually sent to me, so honestly, I have no idea what I got. I have reached out to the seller and will report back when I get the proper part number for the kit I currently have.

Here is the Kit TF197 https://www.lrparts.net/tf197-terrafirma-a...ssic.html, interesting as this states "stock Height" but the springs are HD for when carrying 300kg+ of gear, winches, etc... which I would NEVER do... no wonder I bounce around like a pop-corn kernel. But, visually this does not match with what is on my car.

I did find this kit and ordered it, as it appears to be a true stock height kit, which includes OEM speck springs (I can always send it back):
