Is that your white 242GT on Hemmings with the red visor windshield and private seller out of Connecticut? If so, that looks very, very stock ride height. BTW, those are the later 940 10-spoke 15" alloys (like mine), not the original 5-spoke 15" Virgos. I know the rim widths are close, but not identical, also the offsets. If that's yours then maybe look a bit further into this the next time you go to buy tires to get a low profile while making sure you maintain fender clearance under max load (especially with lowering springs) and as well maintain reasonable speedometer accuracy.

To carry on here with general comments for you now that I've got a better idea of where you're coming from, if you need struts and shocks than I would probably also go for the Bilstein B4s as a mild upgrade from stock. FCPEuro and other places also carry them. I once put Bilstein Sport Tourings, probably similar to the B4s, maybe a hair more aggressive, on our '85 245 wagon and was very happy with them for everyday driving along with the ipd sways front & rear.

Being a wagon used for hauling and trailering, I went with the ipd overload rear coils, same as I've done with one of my 940 wagons -not so good for everyday driving when lightly loaded, hopping over speed bumps even at low speed. Max loads and lowered springs don't go together. Got all the ipd stuff on one of their famous sumnmer garage sales, like over 30 years ago. I was helping a friend move back from Portland and we stashed them in the middle of the moving van load to avoid taxes and duty crossing back across the border -I can admit to that crime now as the Statute of Limitations has passed. :)

If I had a 242GT like that in excellent condition with no rust and low mileage then I'd certainly think about giving it a bit more sex appeal, especially being plane-Jane white (I prefer the classic metallic red 242GTs, second is black). You've already spent a good buck on it, so a little more to give it a more impressive look worthy of its reputation and collectibility strikes me as an investment. I'd probably want to go full package ipd with sways, sport coils, adjustable panhard rod, and front end poly bushings, but probably stop there. Things like adjustable torque rods, strut tower braces, cross member lower brace and tower-to-tower strut brace would only be there to impress those opening the hood or the muffler kids when it's up on a rack, while making the ride even stiffer.

I'd even go so far as to think about blacking in between the taillights. Volvo sometimes did that on GTs using a black decal, same time they did the silver or orage reflective bumper tape stripes, and some had a red reflector panel matching the taillights. I recall those were also available as orderable accessories from Volvo, but they were perpetually out of stock as they were popular. Some may have a better memory of this than me.
