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

Is the above video with it before the spring change or after ?
Thanks Calum.

Subject: Re: [Quantum Owners] Lowering springs for my 2+2. When I bought my 2+2
Turbo it was extremely low and was a pain to drive, crashing and bumping over
rough roads and torque steering when throttle was used especially when pulling
out and overtaking. In fact it was hard to avoid hitting the car I was
overtaking!After taking advice from the members here and especially Jim I
bought some fiesta 1400 fronts and 1100 rears as I recall, and that was 5 years
ago and since then my wife and I have done many trackdays and road miles with
no problems.Here is a videohttps://www.youtube.com/watch?v=HAnB-h9PhgM where
we play with a Lambo Gallardo who had my wife on board and later he took me
round too and being in a supercar driven flat out is a great
experience!CheersJon

Hi Dave, I presume that your car was made before Quantum decided the rear of
the car was too low and added the spacer to the shock and the got the longer
rear springs made.
I don't think it disagrees with what i said, just your car pre-dates it being
implemented.
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.
Regards
Dave English
