I fitted some Spax adjustables and that seems to have done the trick and the
springs are my new 1.4 front and 1.1 rears the rear spax are on their lowest
setting and the front quite a lot stiffer but able to soak up our third world
roads that we all enjoy.
My 2+2 still has a tendency towards oversteer which I find strange on a FWD
car. I may take off the rear antiroll bar (only fitted to XR2) because I think
that our cars are lighter at the back than a Fiesta, or I might fit a front
antiroll bar.
Cheers Jon 2+2 RST

Subject: Re: [Quantum Owners] Quantum H4 Suspension/Wheels/Tyres
I looked at getting some springs made with a changing rate to get the
softness but firm up on heavy loading ( full boot or shock loading )
This opened a HUGE can of worms, , thickness of the metal rod, number of
coils, overall length blah blah blah...
I did try some spring assisters used by caravanners but this still did not
help ( before i noticed and replaced the leaking damper )
I still think there was another issue on the rear there somewhere.
Thinking about it the issue only reared its head after the tyres were changed
from Yokohama A420's to Toyo proxy1r's
Firmer sidewalls ? different width at the tread ? who knows? car was sold.

Thanks to everyone for responding to my question on suspension and tyres,
since raising my query I have realised I made an error, my car is actually
fitted with 205/40 x 16's and not 215/40 x16's nevertheless these are just too
big.
Also since driving the car for a few weeks I have noticed the following:
1. The front suspension is generally OK but when driving at speed over long
undulating bumps it can become a bit 'floaty as if the front shock absorbers
are on the way out. I have not noticed the front tyres rubbing even on full
lock despite the wheel and tyre size, although the turning circle is poor and
so it is possible the power steering rack may have been restricted?
2. The rear suspension is very harsh and badly crashes over bumps with the
tyres frequently coming into contact with the wheel arches.
My first thoughts are as follows:
3. Buy some 15'' alloys and suitable profile/width tyres to get the car
back to a more sensible wheel and tyre size.
4. Buy some used 1.1 rear struts to try and get back to a 'normal' set up.
I will then take it from there.
Just one more question, has anyone ever had custom springs made for an H4?
My thought on this is that if I weighed the load on each wheel it might be
possible to get some springs made that are more in tune with the weight of the
car using the standard struts plus better shock absorbers or possibly suitable
coil overs?
Thanks

what's the chassis Q... or reg M254... ???
Looking to hear news of our old one.
Aside from that what suspension is on the car now? standard looking
units, cut off springs?
Adjustable (i guess not) our 195 15 somethings did rub the arches but
only on the tyre wall.
I did change the suspension for new 1.1 springs and monroe gas struts but
it still rubbed.
was only noticeable after changing the tyres, I did not get round to
replacing bushes but what effect this would of had i dont know.
- Jim - what internals do genuine fords have? i think one of mine was
leaking oil.
Based on that look at oil replacements.
Caution on the front struts as MK3.5 1.6 Si have a larger bore strut than
the Mk3
Purple Polyurethane bushes tighten up the handling no end, the whole
handling was fine in my view for every day fun spirited driving.

Hi I have recently purchased an H4 and will shortly be joining the
owners club.
My question concerns suspension wheels and tyres.
The car has a 1.6 zetec engine and is based on a 1995 Fiesta so guess
this is a Fiesta Mk3.5 but I am not sure.
The tyre size is 16/215/40 which just seems too wide for the car, they
are virtually projecting beyond the wheel arches and the rears rub the
arches over bumps.
I don't know what the suspension set is but the front ride height
seems on the high side and the rear is a bit low and the rear
suspension seems firm to say the least! In fact it really is spoiling
the car on normal roads, on the plus side it corners like a go-kart.
I have read that the 'factory set up' was standard 1.6 Fiesta
suspension on the front and 1.1 on the rear, I have do to something to
improve the suspension as a matter of priority,I was thinking about
just buying some standard 1.1 springs/shocks for the rear and taking
it from there.
There are also a fair number of alternative suspension manufacturers
such a spax, koni etc. who sell lower/stiffer/adjustable alternatives
and I don't know if this would be better?
Also any guidance on wheel sizes/offsets and tyre sizes would be very
much appreciated.
