Plein d' infos sur "composite rear springs"

There has been a lot of debate about Interceptor rear leaf springs - Someone
mentioned "Composite Leaf Springs" - I was not even aware that such things
existed!
I found four sites that may be of interest to members:-

I also found the following, regarding the choice of shock absorbers after
the fitment of Composite Leaf Springs to an MGB.
I believe some of this information may be relevant to the Jensen community
"Composite Leaf Springs
Rear Telescopic Shock Absorber Choices
With the rapid response of the composite springs to road conditions, the
fitting of gas charged telescopic shock absorbers should be considered.
The old OEM type shock absorbers just wont cut it with this type of monoleaf
spring.
If you are happy with your archaic OEM steel springs & OEM shock absorbers
then "God Bless You". Please, if you want to start driving a sports car,
like a sports car should be driven, you should really be updating to modern
day products, otherwise, take out plenty of life insurance for the Wife &
Kids.
British Automotives specially valved KYB (non-adjustable) shock absorbers
are specifically design for the MGA & MGB models. These can be a complement
to the composite springs or simply installed with your OEM springs.
The valving is a compromise between the Koni and Spax units.
Below you will find information on a series of tests that we did with
various shock absorbers. These tests were conducted quite some time ago on
British Automotives modified 1979 MGB' Limited Edition".
1. OEM (front and rear) - Gave an all around nice smooth ride, especially at
freeway speeds.
2. OEM (uprated front and rear)- Gave a much harsher ride on slow uneven
surfaces with the ride smoothing out at freeway speeds. The vehicle was then
refitted with the OEM regular shock absorbers with the following rear shock
absorbers:
3. KYB (this was our first revalved test shock absorber set) - Gave a harsh
ride on slow uneven surfaces, which appeared to be harsher than in 2. Ride
smoothed out a freeway speeds.
4. Monroe Sensatrac - Gave a very harsh ride on slow uneven surfaces as well
as at freeway speeds. This was an interim shock absorber, therefore, no
longer recommended.
5. Bilstein - Appeared to have similar characteristics as in 3 & 4. above
6. Koni - These were set on the softest setting (straight out of the box).
Nice smooth ride all around and comparable to 1. No other rebound
adjustments were made due to the fact that these later designed units needed
to be completely removed from the vehicle for adjustment purposes.
Incorporated in this latest design was a bump stop, a worthwhile addition.
7. Spax - These were set on the lowest screwdriver slot adjustment and were
comparable with 1 and 6 above.
8. Spax - Adjusted to the maximum by way of the screwdriver slot. Almost
undriveable.
9. Spax - Readjusted as in 7. Extensively tested on Highway 1 (Coast
Highway) and the hills in Marin County. Very hard to fault at all.
10. British Automotive's KYB custom valved shock absorber. Performed similar
to 6 & 9 above. A rear suspension fitted with composite springs and gas
charged telescopic shock absorbers is about as good as it gets without going
to an independent suspension set-up. "
