Have you already experienced 3-4" of sag when loading your car? Are you going to be towing a big trailer with max tongue weight, or are you just going to be stuffed with camping gear and stuff on the roof? The reason I ask is that you may not have as much sag as you're worried about.

For temporary use, you could consider coil SumoSprings if getting stiffer rear springs might not be the best thing for a vehicle that isn't routinely loaded and you're concerned about ride quality.

I've never used these myself but just based on the few forum members who have used them, they're ok, can fall out if you don't zip tie them in, and probably aren't good for long term use.

When @Blorky installed his, they didn't have holes for zip ties and his fell out. He was pretty happy with them up to that point.

It's not the best solution but an inexpensive temporary one that does help.

 

I

might be on the road trip for 6-12 months loaded on a roof cargo and camping gear inside the rear and back passenger. Yes, I have already loaded the car and it sags about 3-4”. The dealership told me to go aftermarket to help with the sag.
I’ll definitely look into the Sumosprings. Thanks!

 

Heya - Couple of updates re: coil Sumosprings. I bought fronts and backs from Amazon in 2022, and they didn't come with holes and zip ties to keep them in place, as several user reports indicated. I called to see if I'd accidentally gotten a grey market version. They said no, it was a new design because I didn't need the zip ties. They were good until both rears fell out a few weeks after installation.

I had a series of emails/convos w/ SS and at that time, they mentioned that the sizes listed on both Amazon and on their own site as being appropriate for my 2020 Outback touring were incorrect.
The sizes they recommended then were:
- Fronts: CSS-1195 ($246/pair on Amazon currently)
- Rears : CSS-1094 ($ 175/pair on Amazon currently)
They were really professional and sent me the corrected sizes, even though I didn't buy the originals from them. Kudo's for that.

Their site currently uses a printable fitment guide for you to order the correct size devices. Coil SumoSprings® by SuperSprings® International, Inc.. NOTE: Amazon's listing for the recommended sizes for Outbacks is still incorrect.

The replacements didn't come with holes for zip ties, or for the zip ties themselves. I don't know what they do currently. It was easy to drill holes in the coil and add zip ties. (I was kinda peeved with the process at that point and used heavy duty 250 lb ties. The springs are realistically not subject to that degree of stress, and you can probably use 50 lb ones.) Installation isn't hard, but I did it with the tires off. Might be a serious PITA if the tires are on.

I'm currently driving with the correct size ones on both front and back and am happy with them. I candidly was just irked that the original design supplied/recommended zip ties, then changed them to not use zip ties, and there was a flurry of "they fell out" reports. They're a good product for my use case - 1x/month need to drive several hundred pounds of mulch/garden stuff/lumber/whatever. They don't really affect driving dynamics significantly when the car isn't loaded, but definitely help sag and car sway going around turns when the car is loaded.

What's your guesstimate of added weight from the roof cargo/camping gear?

I’m guessing 600-700 lbs. Essentially 5 grown adults inside the vehicle give or take.
