Probleem: G Front dampers and
When I bought my
Sabra the front springs and dampers were obviously not original. Original
ones were Girling (spings & dampers in one set).
At first I
replaced the dampers by Mini-dampers Monroe R 1045 B1B80 but the parts to hold
the spring were welded on the dampers wich isn't the easyest thing to do.
The springs I
had made by:
03/353 90 23.
The springs were made on a trial and error-base, it was only when the last pair
of springs proved to be correct that I met Jacques, who confirmed me that his
front-springs were the same size as mine. The order form of the last pair
of springs states they are 290 mm high, inner diameter 55 mm, diameter of the
steel 10 mm and (total) 13 windings. Same day a friend-engineer had calculated the same
size for these springs (based on my errors).
Different Sabras still seem to have different front-springs!!
Perhaps if you order the springs and you are going to use the SPAX-dampers, you
could order them inner diameter 56mm.
After some years
of driving it showed that the dampers were not designed to take all the weight
of the car. I.e. the connection - eyes to take the bolts were pushed out
of of the center of the bigger eye at the end of the dampers. At MOT they
told me I had to have it fixed.
Geoff Cooper advised SPAX-dampers G462S190+0.5"BUSH
Seems to be only one SPAX-dealer in Belgium:
014/51 64 31.
work with the above part-numbers but they decided that I could use G452-dampers.
Ordered a pair of those (they're adjustable) and they fitted nicely apart from
the fact that the fitting for the springs is 57mm wide.
As my springs were made 55 mm inner diameter I cut off 2mm from the inside of
the springs (at both ends) to make them fit.
Made up dust covers for the dampers from silicone-tubes.
The car seems to
sit nicely don't know if it will be ready to race but racing isn't my first aim.
We'll have to see what the car does after a long trip. Repair december
Added 01/08/2005...Attention: The Spaxes made driving
much easyer, lots of vibrations disappeared; with the Spaxes fitted the car had
almost NO trouble anymore when it ran into a bump or a hole with one front wheel
only. It behaved much better although I had let the dampers on their
"softest" position. Recently been driving around with original
but old dampers from one of Jacques' Sabras and the car started wobbling again.
We learned that the front dampers of the sabra must be hard to drive comfortably.
Why did I put on Jacques dampers? The rod of my left
damper broke off (had done some 2000km).
Not clear why it broke:
Could be I tightened the bolts of the upper fixing point too tight, thus
locking the outer eye of the damper and forcing it to take all the play forced
by the flailing-arm going up and down with the rod itself.
Could be I should order dampers with a greater "outer eye": the
original dampers have a lot more of rubber between the inner fixing bush and the
Could be the rupture was caused by the fact that the former owner of my
car had the lower fixing bolt welded to the flailing arm in an incorrect angle,
this can only be sorted out in comparing different Sabras with very precise
measurements. The extra rubber of the original dampers could have taken this
Could be that a damper should be able to take these small movements and
there has been a construction error in this one (why didn't the right one brake
off: it's done 250 km extra (one fourth extra)?
Could be a combination of the above. Anyway I'll stay with the
spaxes, and if one of them brakes again next year I'll try for more rubber
between inner and outer bush.

Hi Jef, I found a low budget solution to replacement front
I bought a pair of SACHS 5334 shock (old Jaguar rears) absorbers.
I cut both loops (bushing mounts) off 1 of the original Girlings. [I wanted to
keep 1 original intact].
Then I sliced the lower loop on the NEW shock and welded the old shock
loop onto it, to achieve the correct length.
The SACHS shock was 3/4" short on the lower end, but the other dimensions
were very close.
I wanted to use the original upper metal dust boot to properly align the spring
but the upper spring stop diameter radius was about 3/16" too large.
The shock would not fit in a lathe, so I trimmed a large washer and tack welded
it to the underside of the stop to hold the dust boot in place.
For the lower bushing I used a polyurethane (hourglass style) bushing from
"ENERGY SUSPENSION" [hyperflex] part # 9.8107 with a bronze
sleeve from a local hardware supply to fit the 1/2" diameter mounting bolt.
I believe it will fit perfectly, I hope it will perform properly but will not
know until the car is roadworthy.
See the attached pictures. The original is on the left side of the 1st. photo.
