Suspension question

[FRZ951]

Ok. I have a 968 front suspension on my 1988 Turbo. The suspension was already there when i bought the car. Now I REALLY need to replace all 4, front and rear. I bought from alpom a pair of used 944t front struts only.

Now I need springs and hat. So a guy from Paragon told me to buy this: Porsche 944, 944S, 944S2, 944 Turbo and 968 Front Coil Over Kit.. Until here all is find. But there is a problem! Just before checkout, i saw an installation page link at the bottom of the description (Here). As you can see on the third picture, the strut is unmounted to be able to install the red Aluminum Threaded Collar. On my struts, there is crimped metal piece that cant be removed. Then i suppose this kit will not fit? If im wrong, then I need tips on the instalation. What i understand is the kit fit on rebuildable struts only. Struts with metal crimped piece are not rebuildable. Is that exact?

Here is a picture of the struts I bought.(i painted them yellow.they was black):


An other question. My car make 305RWHP with 350RWTORQUE. What is the best front and rear springs rate if want a racing stiffness and no oversteer. My car is daily driving but I dont really care about the road comfort.

Im currently saving to buy a new house. This is why for now I try to get this used front struts working. I will buy new rear shocks. i know its not the best but for now..

If i really dont have the choice, I will look for those: Porsche Koni 944 suspension

Thanks.

The threaded collar will not slip over the crimped piece. That's why they say it will only work on converted struts.
Your struts are at different heights and look totally collapsed, you may need to convert them anyway.

I see. In fact I need to buy all 4 new.. Ok.

For the springs rate? How much front how much rear? For the Koni Cup, the max for the front is 400 and 600 for the rear. Is this a good setting?

Someone know a place in CANADA to get this kind of racing suspension? because its 500$ only for the shipping from USA to Quebec.. Thats half the suspension price its a little bit stupid..

Thanks!!!

[968 GUY]

Yeah, for racing, not street. Probably 250 max in front.
Not sure about rear.
On your own about Canada.

Ok.. So 400 for front is VERY VERY stiff.. Too much?


Again for other people that read the thread:

Read the suspension section at clarks-garage.com. Should help you understand a bit better.
Seems loke the 88 turbos had pretty good suspension as stock. Read up on it and maybe you can use that as a starting point.

To convert those struts, you need to buy the koni strut inserts, Paragon Product Code: KONI-8641-1414S-XDO ($194.60 each) The inserts come with all the hardware you need to convert those to a replaceable insert strut.

It's an easy conversion, paragon products has the instructions posted on their website www.paragon-products.com/kb_results.asp?ID=50 Basically you;

1) drill a small pilot hole in the bottom of the strut (carefully cover with a rag while drilling, oil is under pressure and will spray out when you puncture the casing)

2) cut off the top of the strut, and pull out the insert

3) drill a larger hole in the bottom of the strut

Just download the instructions, they give you drill sizes, measurements for the top cut, etc. Takes about an hour to convert both struts.

Or, send the struts to Paragon, and for $165, they will drill, cut and repaint the strut housing and send them to you ready to install the inserts.

400 is not VERY VERY stiff as an absolute measurement but it depends on the shocks and valving. I ran 800/900 and drove on the street with this setup with KW 2 way race shocks. I also replaced all the rubber bushings/bearings with metal / monoball. Ran on 18" wheels and R spec rubber. Ran Racers Edge Camber plates. Still drove this on the street. Really depends on what conditions you drive.
