Still figuring out the best option for my wagon.
  • ST X - KW told me they don't really make a kit specifically for the wagon, so you can use 1322000R with spacers. I think it will be too low in the back.
  • KW V1 - 102200AB is made specifically for the wagon. However, I'm still wondering if it's too low for my tastes, and also concerned by some of the trouble reports
  • H&R - is this actually the best option? Stated lowering range is .80 - 1.75 in the front, .60 - 1.6 in the back, seems perfect for me. Around the same price as the KW V1.

328iX I saw you had part number 28895-4, but the website lists 28895-8 for the F31, I wonder if it's been updated?
I'm not sure if the part was updated. I was the first one to receive the kit and found flaws and worked with H&R to resolve them. They basically had the kit setup with RWD parts.

Yes the H&R range is probably the best, KW V1 and ST are the same thing.

I love them, not the most comfortable ride but it's not bad.

Wow, so H&R's own website doesn't recommend the best kit for the car? That is...strange

Glad that you are enjoying them. When you say "not the most comfortable," are you comparing that to stock, to the prokit/SA combo you've run, or to other coilovers?

I updated my response sorry I was confused.

H&R made a kit that didn't work with the F31, it cost me $5000 in damages after installation. I pointed this out to them and appropriate changes were made.

So I'm not sure if that resulted in a part number change but it appears that it did as I believe I had the -4 kit

And yes, compared to SA/Eibach those were extremely comfortable and responsive.

H&R is on the stiff side for sure.

Thanks for being a great source of info on suspension for these cars.

I keep going back between options, since there really doesn't seem to be a silver bullet. I'm worried that SA/Eibach won't be low enough to get the look I want but on the other hand, all of these coilovers have at least some pros and cons.

I sort of doubt we'll see any more options hitting the market so I'll have to make up my mind!

Whatever you do i'd just go the coilover route.

I tried ACS and Koni/Eibach and the fit just never looked just right how I liked it.

It either had a reverse rake or was just barely level, to where I'd fill up my tank and it would be lower on the rear again, granted the ride was nice.

The stiffer ride with H&R gives me the impression of the car being more planted and connected but I understand some people just can't do stiff.

Yes.
Part number has changed.
New number is, H&R 28895-8.
I have these sitting on my workbench waiting for installation.
Hope to install in the next two weeks. Will do the work myself.

Based on the information from 328ix and wanting the ability to adjust the ride hight, I went with this kit.

I do think of this kit as a semi adjustable suspension.
A true coilover gives you the ability to raise and lower from the shock body without changing spring tension.
With the H&R front strut you increase of decrease spring tension in order to raise or lower. The rear suspension design of the F3x cars does not allow for coilover operation as the shock and spring are separate items.
To a certain degree the rear spring can have some additional tension depending on how high you set the threaded spring adjusting collar.
But at this price point I think it is a fair compromise.
I paid $1,369.99.
I'll report back after installation with my thoughts.

That's good to hear, best of luck with install it should be trouble free knowing you have the correct parts.

Be sure to update once you've driven with it.

I have the damper dynos for this kit. LMK if you'd like them.

I don't quite agree that the spring tension is increased/decreased when changing the ride height.

Ride height is dictated by how much the spring is compressed by the weight of the car. If you raise or lower the perch, the weight on the spring is the same, and thus the amount the spring compresses is the same, so there's no more or less tension on the spring.

The boundary cases where that isn't true is if the perch is raised/lowered so much that you run into the travel limit of some other part of the suspension. If you keep raising the ride height eventually the damper will reach full extension or the bushings will be providing enough counter force and prevent the height from raising any higher. This is equivalent to the suspension being at full droop. Raising beyond that would then be adding extra pre-load to the springs. On the other hand if you lower too much you eventually just sit on the bump stops, and/or hit the damper maximum compression (properly spec'd bump stops should prevent that).

In systems where the damper length is adjusted with ride height they typically do that so that the piston sits in the same position within the damper no matter what height is set. This ensures you have enough compression and extension stroke to not bottom/extend out the damper. With the dampers on our cars the suspension manufacturers recommend a height range to achieve the same thing.

Just got my SR Flatout Suspension coilovers installed for the wagon and they ride great. I'd give them a chance if you're looking for a lower ride height with a smooth and firm feel. These are made to order and are custom valved so do expect a 2-3 week build time. They include radial bearings and camber plates along with electro-plated cartridges. Check them out!!

Key features:
- 20 Points of rebound
- Radial bearings
- Electroplated assembly
- Camber plates included

Kit cost (excluding shipping) - $1,380

At $1380 these seem in line with some of the other options so that's interesting. Is the dampening adjustable though? I can't quite tell.

What would you estimate the drop to be? The stated range of 0.5 to 3" is quite large. I'm wondering if these would work reasonably well for a moderate drop of 1" or so.

Yes, 20 points of rebound front and rear. I would say that you could easily get a moderate drop with these. As shown on my car I have them at the max drop.

Edit: 20 points of rebound not 30 points of dampening - my bad

The rear setup is a bit interesting with the inverted damper orientation (not uncommon with adjustables). With the piston shaft at the bottom is it always covered by the dust boot under normal height? In the pic at full droop there's quite a bit exposed.

Also, are you sure the rear height adjuster is supposed to slot into the original top spring cup? It doesn't look like you can get your wrench in there to the top ring, and most setups have you remove those cups and the adjuster goes straight into the body.

The dust boot wasn't pulled all the way down in that photo. And under normal compression with the car on the floor it will be fully covered. And you are correct about those cups. When they first installed them they left them in by mistake (local shop). I wasn't there later when they noticed their mistake and removed the cup so I didn't get a new photo. I need to take new photos but I'm not sure when the car will be on a lift again. I decided to post these photos for now. Good catch though..

Ok good to know!

I took a look at the site and it's a bit strange, the generic dyno plot they put for the cheaper SR appears to show rebound and compression adjustment with each position (and they say 20 positions instead of 30), but the more expensive's ST series' generic dyno only shows rebound adjustment. Both descriptions only say there's rebound adjustment. Granted, the SR compression adjustment amount is pretty tiny, especially compared to how much the rebound swings.

For the Dyno plot you would need to reach out to them. You are correct about the 20 points vs 30. I was going from memory and should have looked back at their site. To clarify they have 20 points of rebound adjustment.

It's 20 points of rebound not 30 points of dampening - my bad

Thank you for the information, I'll update the list.

I've never heard of them before but glad you're happy, how did you hear about them?

I came across them on IG and did some research and decided to take a chance. So far I really like them and the ride is pretty good. It's my daily so I do about 70 miles a day with them on shitty LA roads.

Installation was straight forward.
Just minor difficulty dropping the front knuckle from the strut and aligning the rear lower knuckle bolts.
One thing to note, the front struts don't have an alinement post to slide into the knuckle slot. There is an arrow stamped into the strut body. Use that reference to the knuckle slot and the struts will be in proper position to attach the sway bar end link.
Quality of components is first rate. I set the ride hight at the highest setting to start. Also added 1/4 more to the rear with shims on top of the spring adjustment body. I don't want to change the rear hight that much from stock.
As of now the front still looks too high.
I have not driven the car at this time.
Will drive the car as is for some distance and see if things settle down lower.
Then I'll lower the front more if needed.
I'll report back after I have driven on various road surfaces.
I'm hoping for a more controlled and firmer ride.
Main goal of eliminating the 4x4 truck look has been accomplished.

I have lowered the front to the lowest setting. The rear is at the highest setting.
Front is maybe 3/16" higher than rear of car. Ride is definitely more firm than stock suspension. Well within my tolerance range. Handling is better giving less movement in right, left, transitions. Turn in response is more crisp.
On my car the rear dropped an inch using the highest setting. H&R says it should only drop 5/8". I wish that was the case. The front had to be set with the full 1.5" drop to get me near the same wheel gap.
I would prefer the rear to be a 1/2" higher and the front 3/8" higher than what I ended up with.
The car now has a more proper balance with wheel gaps and looks like I want.
But I'm forced to be too low in front because the rear hight is maxed out.

I'll report back if I make further changes from here.

The good thing about the rear height is that it's not very difficult to raise it up. If you're at the end of the adjustment collar for going up, you can make some shims/spacers to add length to the spring.

Hi FaRKle,

Will I run the risk of topping out the rear shock absorber?
I already have 1/4" added between the upper car body/frame and adjustable collar.
