Re: [Quantum Owners] Lowering springs for my 2+2.

['jonathan jackson' via Quantum Owners Group]

Hi CalumThis second video was taken before I sorted the suspension out.the car 
in the video was too low and stiff on XR2 springs.The trackday video was done 
with the suspension sorted and though its difficult to decide what is best it 
drives without vices now and does 1 min 28 round Combe in my hands (which are 
getting slower as I age!cheersJon

Hi Dave, I presume that your car was made before Quantum decided the rear of

I don't think it disagrees with what i said, just your car pre-dates it being

I'm sure the intention with the 2+2 when it was designed was that it could take 
XR2 suspension parts, they just got the calculations a bit wrong to start with.

Hi Calum

I've got Q2-009 which is definately an early one.

Originally I had the standard XR2 springs on the front and standard Mk2 1100 
springs on the rear, tyres where 185/60 13's (again standard XR2). The rear XR2 
springs were too short, the rear tyres sitting against the inner arch before 
the springs took the weight.

I've checked my build manual and looked at the car, and there is nothing on top 
of the shocks or the springs. The shocks were (and still are) standard XR2. The 
only 'spacer' is inside the spring for the bump stop, it doesn't affect the 
spring or shock length.

Hopefully a picture is attached showing my car with this set-up (the one with 
the tent behind it). This is about as low as you want to go, a rough road would 
see my stainless steel manifold hitting the ground, I've now got a thick plate 
welded to it.

I currently run with the Quantum springs and 185/60 14 tyres on Sierra wheels 
(185/60 13's were getting hard to find). It's a little softer and a bit higher 
off the ground but the bigger tyres help to the fill the arches. I don't know 
if these tyres would work with XR2 front springs because I changed my springs a 
while before I changed the wheels. The second photo shows this set-up.

Your 185/55 14 set-up has the same diameter as the standard XR2 tyres so XR2 
front springs will be about right but don't put XR2 springs on the rear.

I know that this info disagrees with some other posts but I went and looked at 
the car to confirm what I thought and read my 2+2 build manuals (I have an 
early one, partially photo copied from hand written, and a later, standard 
one). The way I have described it is what the manual says and what I saw under 
the car.

Hope this helps and doesn't add too much confusion.

Re: [Quantum Owners] Lowering springs for my 2+2.

['Robert Craig' via Quantum Owners Group]

My current 2+2 is chassis no 063 and I have fitted standard XR2 on the front 
and 1100 on the rear with GAZ adjustable dampers 15" wheels with 195/50 15. It 
handles well and is high enough to get over speed bumps (slowly) but does 
bottom out on the wheel arches occasionally.  I also had this set up on chassis 
263 originally with 14" wheels and then with 15" and 195/45 profile tyres.  
Similar handling.

Re: [Quantum Owners] Lowering springs for my 2+2.

[calum mcpherson]

Thanks for reply Dave, interesting reading.


I was under car today and as my previous replies have noted what feels like an 
internal extension on the top of the rear shocker ( inside fibreglass strut 
mount accessible from below car), which would make sense as it is believed my 
car is an early model (see pic of strut top in boot, does this look similar to 
yours ?) As for rear spring, looks fairly std. top & bottom rubber mounts and 
internal bump stop , I did measure spring length at about 250mm with car 
sitting on level ground.

My tyre gap (car empty) is 70mm front , 60mm rear , arch height 615mm fr. 610 
r. and back and front end I have approx. 230mm ground clearance.

Car previously had 15" rims with 195-50-15 tyres , which were oversized, so 
tyre to arch size has increased by changing wheels, although now as it should 
be in terms of circumference matching XR2.

Sitting about the same as my daily X3 (although it has Eibach -35 springs)lol.
Just want it to look right and at the moment it is not looking sporty [😠] .

Thanks again for input.

Calum

Afraid not.
Early 2+2 used Quantum spec front and rear red springs.
The later ones used Quantum spec front and normal 1100 rear.

I'm pretty sure i have a pair of both over at my parents but not over there for 
a little while.

Both the rear spring seat area and the rear shock mount on the body were too 
high on the early 2+2's
The shock had the extension and the special rear springs were made that were 
longer.

You are correct that the spring isn't fitted around the shock but the distance 
between the spring mount on the axle and the seat on the body is too big.

Pretty sure the spacer on the shock is somewhere around 50 or 60mm, assuming 
the spring is the same amount longer than standard you would be lowering the 
rear about that by 50 or 60mm by fitting standard non XR2 springs, which may be 
a little low.
You’d also need to find something to match at the front.

Quantum used to supply special Red front springs,(known as Quantum red springs) 
to give increased ride height, I gather they are no longer available. I would 
think that these are fitted to your car.If anybody has any going spare I would 
be very interested as my 2+2 is too low with the heavy Diesel lump, a trolley 
jack with the 1/2" block board spreader on top, will not go under the sill.

More info from 2015 thread.



Ooops, the scissor jack that fits is in the corner of my garage!

It was standard xr2 rear and quantum red at the front.  The 2+2 is similar  
weight as an xr2 so in theory xr2 springs should work.

For me it definitely needed stiffer springs, the dampers were wound up to 
compensate, which in an ideal world is wrong.

Early 2+2 had higher spring damper points and to achieve the 'on stilts look' 
had I think a 2" extension piece. Mine just had standard length everything and 
was an early chassis.   That's actually a bit of a pain as most of the off the 
shelf stuff for an xr2 also gives a drop so won't fit. Later 2+2 had shorter 
Whatnots. At least that is what we seem to have figured out through various 
posts and discussions over the years.

Preference on what was best to fit tended to align with age, under 40:= stiff 
as possible, over 40 = soft and comfortable.  Your preference may vary of 
course.

Rough starting point would be for soft go quantum springs with first dampers, 
harder xr2 all around, stiff with some damper adjustment gaz standard length 
with xr2 springs, fully customidable proper oilovers (the latter be careful to 
get standard height xr2 else you'll be scrapping the road)

Pretty sure the spacer on the shock is somewhere around 50 or 60mm, 
assuming the spring is the same amount longer than standard you would 
be lowering the rear about that by 50 or 60mm by fitting standard non 
XR2 springs, which may be a little low.

You’d also need to find something to match at the front.
I think i have the extensions at home, will measure one tonight if i 
remember.
Can’t measure the 2+2 ride height to compare with yours as it’s 
currently living at my parents while i slowly do the saloon.

To be sure, check at the top of the rear shock, you should find an 
extension screwed to it.


They used specific Quantum rear springs to make up the extra length.

I’m not sure why the early 2+2 were like this, i guess they did the 
moulds and then realised the car was just too low to be practical.


The front end they could change by modifying the spaceframe, the rear

Re: [Quantum Owners] Lowering springs for my 2+2.

[calum mcpherson]

The length of shock being increased by the spacer will surely only be for the 
extended length of the strut mount and not have any bearing on the spring 
length as spring sits between 2 fixed points on axle & body ? I have been 
thinking about this and doing diagrams all day to get my head round this, 
convinced I'm right, maybe.

Does anyone know the length of the 'Quantum' spec. spring for fronts ?

Pretty sure the spacer on the shock is somewhere around 50 or 60mm, assuming

If your car is one of these then you will need to compensate for that on 
whatever rear springs you get.

My 2+2 has coilovers on the front and standard XR2 rear springs, but mine has 
the high rear mounts.
So i've effectively lowered it around 80mm from the Quantum intended spec, it 
is too low, i have to drive across most speed bumps at an angle and even then 
they hit the engine crossmember or exhaust.
And i can't use it to go to work as the uneven B roads cause similar problems.

Re: [Quantum Owners] Lowering springs for my 2+2.

[Jim Hearne]

Pretty sure the spacer on the shock is somewhere around 50 or 60mm, assuming 
the spring is the same amount longer than standard you would be lowering the 
rear about that by 50 or 60mm by fitting standard non XR2 springs, which may be 
a little low.
You’d also need to find something to match at the front.

I think i have the extensions at home, will measure one tonight if i remember.
Can’t measure the 2+2 ride height to compare with yours as it’s currently 
living at my parents while i slowly do the saloon.

Put my hand up at side of shock, and does appear to be some sort of spacer / 
extension at top. Thinking about it, surely if spring length is reduced this 
would allow drop required (approx. 35mm) as sizes on diagram are with car 
unladen (does drop approx. 25mm when sitting in car). I presume as long as new 
spring weight is correct would still have same travel with lower wheel gap ?



Oh the joys of kit cars.

Afraid i’m pretty sure that’s the higher rear spring and shock mounts.

To be sure, check at the top of the rear shock, you should find an extension 
screwed to it.

They used specific Quantum rear springs to make up the extra length.



I’m not sure why the early 2+2 were like this, i guess they did the moulds and 
then realised the car was just too low to be practical.

The front end they could change by modifying the spaceframe, the rear had to 
wait until they modified the moulds.

Re: [Quantum Owners] Lowering springs for my 2+2.

[Tom Walker]

I played around with lowered and uprated springs on mine (16" wheels) and
ended up going back to standard xr2 on the front and standard fiesta on the
back, but on the back i cut out half a turn to lower it a small amount.

You could probably lower the front in the same way, but be careful as it is
a lot more difficult to put the spring back together again if you take too
much off. ;-)

Re: [Quantum Owners] Lowering springs for my 2+2.

[Jim Hearne]

Unless you are only travelling on good A roads and not going over speed 
bumps you will find lowering springs on a 2+2 rather a pain.


The 2+2 already sits lower than the donor Fiesta for a given setup, the 
XR2 was around 20mm lower and lowered XR2 spec springs will be another 
30 or 40mm at least.
That's why Quantum recommended their red springs at the front and 1100 
((taller than XR2).
As a first step i would just try standard XR2 spec springs, not lowered 
ones.


One thing to watch out for, depending on the age of your 2+2, the early 
ones (up till past chassis number 99 at least) had rear spring and shock 
absorber mounts on the body that were about 60mm too high, Quantum fixed 
this with spacers on the top of the shocks and extra tall rear springs.
If your car is one of these then you will need to compensate for that on 
whatever rear springs you get.


My 2+2 has coilovers on the front and standard XR2 rear springs, but 
mine has the high rear mounts.
So i've effectively lowered it around 80mm from the Quantum intended 
spec, it is too low, i have to drive across most speed bumps at an angle 
and even then they hit the engine crossmember or exhaust.
And i can't use it to go to work as the uneven B roads cause similar 
problems.

I've recently changed my wheels 15" with 195-50-15 tyres to the 
correct set up 14" with 185-55-14, and my 2+2 looks like a Land Rover.
I was going to change springs anyway, but now have brought this job 
forward as not looking as I want.
I understand that the manual states 'Quantum red springs' for front 
and Fiesta mk2 1100 springs for rear, however when looking at lowering 
springs, most seem to be a standardised Fiesta mk2 set up , most 
covering full range excluding XR2 


Anyone got any experience with lowering springs , any recommendations 
would be great .


Car has std. XR2 engine set-up, thanks.
