The kit is worthwhile and an improvement - aesthetically and comfort. But if at all possible, if you want someone installing it whom has done it before. The instructions are shit, and there is a big win to be had if the installer knows prior what spacing to set the adjusters at. They are not easy to adjust once they are on.

What would be the recommended adjustment for full height?

Getting nervous......anyone know if there's an installer in New England, near Boston that has installed one before successfully ?

Honestly, if you just make sure they don't go lower than 25mm front and 20mm rear, install the springs front and rear per the above documentation, move the bump stop per the instructions, nothing else will go wrong. These are simple steps but some seem to overlook them.

To follow up on my last posts, I checked my spring install today and they are correctly installed front and rear. So any ride issues I had were simply from them dropping the car too aggressively upon installation. This is absolutely more comfortable than stock, even with a reasonable drop.

Does anyone have pictures of the MSS kit installed at FULL stock height?!? Please please please..

Do you mean a picture of a car with MSS springs set at the max height for the spring?

If you mean the MSS set at the height of the stock suspension, then it'll look like any stock picture.

I thought even at full height setting it was still lower than stock?

From my experience. 2 out of 3 customers that I install at 0.5" lower than stock, they were having clunking issue from the front.

After further troubleshooting and testing, the noise is caused by front spring being too soft so at that height, it fully compressed when you hit a bump or potholes.
Since it is a short spring at soft spring rate, the coils touched and caused the noise.
You won't hear the noise on even surface, only on bump, dip, and pot holes.

This is valuable info, Ben!

Sorry If I misunderstood.

Does this mean, you should have it more than 0.5" lower from stock to avoid the clunking issue, meaning lower it 0.75"-1.0" ?

Or it's better to leave it higher, at the same stock height to avoid noise ?

Very interesting -- I am about 1/2" lower than stock and I do notice this. Specifically, on the front only, if I hit a "sharp" bump, I hear a "thud". I assumed this was the bushing or bump stock, but your explanation makes more sense. The problem seems worse in Sport or Sport+. Have you been able to tweak anything for these two customers to eliminate the issue?

You need to go lower. 1" at a minimum.

Yes, lowering it to 1" drop, solve the problem.

Would making sleeves for the springs solve the problem?

Haven't tried it. Could possibly help.

I'm confused, but bear in mind most of my suspension experience is on bikes.

If you increase the pre-load (compress the spring), the sag increases and this leads to a higher ride height. Less preload (lower ride height) does result in softer effective rate and indeed uses more suspension travel = lead to higher chances of bottoming out.

So on these front springs, how are you lowering the ride height by increasing pre-load?

Reducing the pre-load lowers the car.

I agree with your statement, but since the spring is engineered by MSS to use short spring at low spring rate, I have no exact answer why they designed it like that.
Maybe because the road in UK doesn't have that much pot holes like in the US?

When I brought this issue to their attention, they blame me for setting the rake at 15mm (which it is what they wrote on the installation instruction).
They want me to set it at a minimum of 20mm, which I argued that their instruction said otherwise.

And, based on my 20+ years in suspension work, that doesn't make sense.
Because higher rake on the rear, means you are putting more weight to the front suspension.
And the whole issue is with the front suspension.

My only guess, if you are 1" lower, before the spring coiled up together and make noise when you hit bump or pot holes, the bump stop will stop it first.
Therefore, no spring clunking noise.

Cheers - as expected then, reducing the preload will lower the car. Yet i hear people say that it feels too firm if lowered. They also state that at OEM ride height (i.e. with more pre-load) that it soaks up the bumps better?

Maybe you already told me the answer - its the bump stops intefering and muddying the waters???

In technicality, it is correct, but the amount of pre-load do comes in effect.
Too much pre-load, will make the car unstable.

And based on 2 customers that I've started at 0.5" drop then lowers it to 1", 1" lower is actually feels better and handles better.

Hi RG I presume at stock ride height this isn't an issue? Cheers

You can't set it up at stock ride height.
The adjuster will be out of thread where it will be safe enough.
And, if you can, you'll have the noise issue when you hit pot holes or bump at moderate speed.

At 1” drop would you still get a substantial increase in ride quality?

[slicer]

Let me add something as it seems folks aren't fully grasping (based on what I'm reading).

The MSS kit has a spring length and spring travel designed around lowering the ride height. If you run the adjusters at full stock ride height the spring will bottom BEFORE the bump stops. This results in the noise and abrupt bottoming that folks are describing. Imagine the spring fully bottoming - metal on metal. The lowered ride height mentioned by RG results in a softer ride because the suspension is bottoming on the bump stops which is a progressive, soft, noiseless sensation. This is counter to some of the understanding of those posting on the thread. You would typically think that a higher ride height, which has more shock travel, would yield a softer ride. This is typically true UNLESS your spring runs out of travel and bottoms out prior to shock/bump stop.
