1303 Strut options.. Research

I checked the site this moring, but couldnt decipher whether they offered that setup for the 1302 or not...

Maybe some of you Europena Guys can help me out with that.

Hello Vujade, I believe you need the 1302 setup (3 bolt strut). I can tell you they sell this setup. It costs 547 euro. If you need translation help or so just let me know. Greetings from Holland.

Thanks very much. I may take you up on that when I am ready to buy them.

what do you think of the ride with the Kerschers?

Is it too stiff or can you adjust it softer to?

Do tell please!!!

vujade, The ride is phenominal. Comfort level is very high, which is desirable with low-pro tires!

The pic in my earlier post clearly shows a 1302 strut.

No spring in the world has an adjustable spring rate. A springs 'stiffness' is a product of material and dimension.

Spring stiffness (uniform open coiled helical spring within elastic range)

= Force / Compression, measured in Nm^-1.

This is linear (y = mx + c), i.e. double the force, the amount of compression will double too. This can be applied to the springs used with most aftermarket struts. This much can be cofirmed by appearence.

The stiffness of the Eibach springs, however, is second order (y = x^2 + x), due to the change in the geometry of the coiling. The Force / Compression curve will show that the rate of change of compression decreases with respect to an incremental increase of applied force. This makes all the difference!

The height of the lower spring plate is adustable, this only determines the height of the vehicle at equilibrium. On the road, the amount of spring compression is determined by the mass and position of the centroid (the point where the mass of the car is believed to act) Move the centre of gravity and back and forth and see the front and rear spring compressions alter. e.g. Move the centroid forward, raise the front lower spring platforms to compensate for the resultant change in stance and you've just softened the response of the front-end (after you have increased the damping (by adjusting the size of the orifice in the valve))

MattKab! :silly:

Thanks MattKab.

Sorry about the name

[MattKab]

No worries!

Hi Justin,

From your description of the adjustable struts, sounds like you have done this before. My first question would be getting the parts. For my 72 super, I was leaning toward using the Civic spring kit from Vdubcustoms, but seeing you post, I am not considering going the route that you describe.

do you have any more details about where to get the parts in the parts list that you describe? I believe I could handle the welding with a few pictures to go by.

Any help is greatly appreciated.

Thanks,
Rick

Minimal/ no welding required - check this link out for a description

My lower stop (for the threaded body for the bottom spring platform) sits at the bottom of the strut- but then I've got a 350mm long spring - you may find yours fits differently.

Cheers
Jeremy

Can anyone make out that site at all?
I speak read and write 4 languages. None of them are german and I don't even know the $ exchange.
Does Kersher have an english version?
I have a 74 1303 in need of suspension.
