Thread: How many interested in a new high end coil over at a good price?

One more question.

How much of the damper body do you recommend to have threaded into the mount? As deep as the damper is wide? More so?

Depends, normally around 25mm for normal dampers and 80mm for MacPherson Strut.
We have a hole in our aluminium bracket, and the top of the hole is about 28mm from the top of the bracket.
I tell customers if you can see any thread in the hole, then you are safe.

Realistically, I never really got to the point where customer run out of adjustment if they are trying to achieve a higher ride height.
If it only small adjustments, you can also use the springs pre-load to raise the car up a little bit.
And if you are trying to get a lot more (we done a set for a BMW Mini RallyCross Car and that needed clearance and travel), we just use a longer core unit.

Thanks for the info ! Looking forward to the range of specs to choose from

Nope. Looks like you dodged the majority of them.

Good luck.

how much bump travel does the strut have?
how much of the bump travel does the strut have at ride height?
how much droop travel does the strut have?
how much of the bump travel does the bumpstop take?

They're rebound adjustable, but are there any changes to the bump characteristics when changing through the 32 adjustments?
Is the strut valving digressive, regressive?
Are they valved for a lot of low speed bump?

The travel depends on the car and also springs rate.
We do make changes for specific chassis so if we do develop for the B chassis, then we can decide what best suit the need of the community.

As for the bump stop, it depends if you are talking about the Zeta-R or the GT1.
There are a few different bump stop for the Zeta-R, it will depends on application.

As for the GT1, we have a unique made progressive rate bump stop.
The bump stop are made with a specific hardness polyurethane and is design to crush mechanically before the material begin to compress.
It is similar to the Eibach ERS bump stop except we have a specific rate for each section so we can select what range of progressive rate will best suit for each application.

We have compression and rebound adjustable combined in our suspension.
The bump characteristic change as that is what gives you the steering response on the stiffer setting.
Valving is digressive, and they are not valved for a lot of low speed bump.
It is a road suspensions for road tyres, so a square setup like Bilstein isn't want we want to provide as that will make the ride bone shattering hard.

The bump adjustments does get more "square" as you go stiffer on the adjustments.
They are fine for occasional track use, but they aren't race suspension and isn't valved as so.

We do make race suspension, but they are design for race car racing on race slicks, so it is a completely different setup from what we would offer and classify as safe for a road car.

@MeisterR Would you be so kind and answer some of these questions, please?

As far as manufacturer go, we have used multiple manufacturer and we do keep those confidential from contractual agreement.
Just as our manufacturer will not release info of their relationship with us, they do not release info of who else they work with also.
Therefore, at best you can "guess", but it may or may not be true.

Also, we have our own specification with our manufacturer.
So just because the suspension look like someone's else's, the specification will probably be different.
What that mean you it will yield different performance characteristic also.
It is like Volkswagon and Audi, just because they they share chassis and is made from the same group, their specification makes them a different car to each other.

As far as springs, we don't have any test for them.
They are average quality linear rate springs, but we don't have a spring dyno to test them.
We do offer Eibach ERS springs as an option if exact linear rate springs are needed, and that won't need testing at all as Eibach is going to be as accurate as they will come in all practical application sense.

As far as shock dyno goes, as I have said above I generally don't release this info.
BUT… as I am here… I am actually interested in what owners are looking for?

If you are able to have a shock dyno any way you like, what do you want to see? And why?
Is there a specific figure you want to see, or a specific graph shape, and why?
Because normally I get ask for shock dyno, but the owners actually don't know what they are looking for or the reason of why they are looking for something specific.
So that is why I want to ask what owners of the SR20 community are looking for and why.

Jerrick

but Eibach ERS isn't that great.

What about for the rnn14 chassis, can you answer the above, as its nearly identical with a slight difference in rear ride height. just an fyi, i own an rnn14 gtir that is used for autox.

Anyways, thanks for trying to answer ambiguously... i'm looking for something with a lot of low speed bump as these cars are so so slow to transfer weight
