Springs may not be simple to find used, at least the 140lb ones...

Cant hurt to ask around though.

Little Foreign Car shop, Watertown MA
Autosport Engineering , Stow MA
Mikes Autobody, northshore somewhere.

All have had 914 race cars...and all have had large spare assortments.

The other place to ask around might be 914club...
More northeast guys kicking around there, though I have not been there in a while.

Romanowski might also know where some spare springs might be.
He has a 914 racecar, NH region.

I'm being offered 165 lbs springs - what is the concensus on these?
I think they will be too stiff for me for the road and without stiffening the front will make the car too "assy"

EDIT: they are proggresive so maybe not too stiff?
Also, what role do struts/shocks play in AX?

I don't like progressive springs but you should be fine with 165 pounders. The car will understeer much less but the car will be tail happy. This will give you a reason to upgrade your front swaybar which is your next step anyways.

I'm thinking that because they are proggresive the ride won't be so stiff as to entirely ruin its "date car" status?

Not that big of a risk really, I have a set of Konis to mount them on so I can leave the 100 lbs springs on the stock shocks.

I don't think 165 lb springs would be too heavy. I'm running 250 pounders on mine and its not nearly as bad as I thought it would be.

If those springs are like the ones I had, they are not progressive. There are a couple coils that are wound tighter than the rest and they go solid when the car is lowered to the ground yielding a 165# spring. If you mount them on your Konis, you will probably feel the ride is a lot stiffer. I think what you will feel is the stiffer Konis not the springs. IMHO

Thanks Bill

So what you are saying is they are not really progressive but, shocks aside, they ride ok?

What are you running up front (torsion and sway bar)?

You don't want what I've got. I'm married and don't take the 914 out on dates! (IMG:style_emoticons/default/biggrin.gif)
I've got 22mm front Tbars, 19mm front sway bar and 225# rear springs. The car is so stiff I don't like driving it on the road. It gets driven to and from the AX only (IMG:style_emoticons/default/sad.gif)

So I bought a set of new in box 165 lbs "progressive" springs.
I'll mount them on the Koni red shocks that I bought last year using home made spacers to get the ride height in the right region (threaded adapters being considered as a future upgrade).

If the ride is acceptable, they will stay on.

If the ride is too harsh I will save them for AX and mount a stock rear bar for the street.

I am also looking to make my front sway bar adjustable so I can stiffen it up a touch.

thanks

Are the Koni reds adjustable? I would set them at full soft if they are. At least try to get a fair comparison.

Father's Day.
I appreciate the offer and may take you up when I try to make some adjustable sway bar arms!

So here are the springs I purchased.

Can anybody venture what size spacer I should use to get these to about the same ride height as 100 lbs. springs?

post a pic of the shocks...

My bilstiens are adjustable.
I can setup my 180 lbs springs at stock height already.

Otherwise...
Pull the shock and measure it unloaded.
Put the koni together wit the new spring (no spacer)

Measure both unloaded.
Stand up the setup shock, (tricky part) balance a wheel on top and put your weight on it while measuring it....
Fun

I'll take a picture, but they are not adjustable.

I was thinking I could measure the sag (jack the car up until it starts to lift the tire and measure that vs. sitting on the ground) with the 100 lbs springs and then try some calculations based on free length, installed preload and spring rate to come up with the height.

Otherwise I will just mount them once, measure, unmount, dissassemble, install spacers and remount.

Since the springs are not here yet, the math might be fun to try and the worse thing that will happen is I need to dissassemble as above...
