| I'll add this as a reply here rather than create a new topic...
Which is the most significant in affecting the hard/softness of ride:
the spring or the shock absorber?
I want a ride that's smooth but firm, hard without being a bone-shaker,
definitely not soft or squishy, and with minimum body roll.
Obviously harder springs will reduce body roll (how "hard" are 354 lb ft
springs?), and thus give a harder ride. But to what extent do the shocks
affect the hardness of ride, in addition to their primary purpose of damping
oscillations?
How much variation in ride do adjustable shocks give? How much dearer than
non-adjustable shocks are they?
The suspension set-up is cortina at front, and triumph coil-overs with
trailing arms at the back.
As the front springs can't be adjusted, I need to get it right first time!

| Hard springs in a lightweight car tends to lead to the thing
bouncing around all over the place. The strength of the spring
must be matched to car weight, but I have no idea of how.
Anti roll bars do seem like the best way to keep the car flat
and to keep the ride acceptable.

Hard springs don't make a light car bouncy - lack of suitable shock
absorbers will make it bouncy. If you don't absorb the rebound with
the shock absorbers then you're going to bounce down the road no matter
how heavy the car or soft the springs.

| re: .10
For "bounce" in .9, read "hop". The car will hop all over the
road, not bounce. The basic point is that the wheels don't stay
on the ground too well when you hit a bump. I had first hand
experience of this with my Moggy 1000 van. When I converted it
into a pickup, there was almost no weight at the back end. With the
standard van rear springs, taking corners on a bumpy road was real
fun ... it hopped all over the place. Also, the dampers did nothing
to prevent this because the springs hardly moved at all, so there was
very little for them to do ...

| I have adjustable Koni's fitted to the front of my Ford family limo.
They are adjustable from soft, (about the same as the standard Ford
shockers, before they gave up the ghost at 15000 km, to HARD,
uncomfortably solid. Actually, if left on the hard setting, I think
that the mounting points would give way pretty quickly.

| 515.13 | So, to summarise... | IOSG::MARSHALL | Argle Bargle IV | Wed Jun 20 1990 14:49 | 8 |
| From the suggestions given, this seems a sensible policy:
- don't worry too much about the hardness of the springs. Because of the (lack
of) weight of the car, better to err on the side of softness.
- get adjustable shocks, and use them to get the hardness fo ride right.
- fit an anti-roll bar (if only one, at the front?)

| ... how do you make a piece of bent bar "adjustable"?

| adjust the posiotion that it fixes to the suspension arm ???
|
| 515.18 | OK. | IOSG::MARSHALL | Argle Bargle IV | Wed Jun 20 1990 18:24 | 3 |

| 515.20 | I don't like KONIs | NCEIS1::CHEVAUX | Patrick Chevaux, Nice, 828-6995 | Tue Jun 26 1990 16:58 | 18 |
| I'm not too enthusiastic about KONI's for road use. I currently
have 4 KONI's on the MVS VENTURI and
- they are NOT adjustable (although KONI can open them and change
the parameters for up and down movements)
- they are very hard when cold and
- too soft when warm
We have tried several things to improve this with no result. MVS
have actually switched to BILSTEIN or DE CARBON which are much better.
I've had BILSTEINs on several PORSCHE 911s in the past and I've
always been very pleased with them.
Now I've had KONIs on a RENAULT 8 GORDINI a long time ago and I
was pleased with them.
Probably a problem with weight. The VENTURI and the 911 are heavily
loaded on the rear axle.

| 515.21 | KONI's for the G40 | FLYWAY::SLUIJMERSM | Mark Sluijmers DTN 760-3458 | Wed Dec 08 1993 13:39 | 11 |
| I tried to call Demon Tweeks today but the phone number seems to have
changed.
Could anybody out there give me the new phone/fax number.
What is the approx. cost for KONI's for the Volkswagen Polo G40.
Thanks in advance
