fitted springs to the disco this afternoon, Britpart's finest...
OK... NRC2119 (RR/disco diesel front) look pretty good on the front of the
V8 disco, it looks to be sitting about an inch higher than it was and a bit
stiffer too.
HD 90 rears have achieved a similar result at the back, although they appear
to be very similar to the standard disco springs that came off it. These
are the RKB101230/101240 pair, which are dual-rate - the lower rate is about
the same as the only figure I could find for the disco rears, the upper rate
being higher. The ones that came off are alleged to be single-rate, but
they seem (not measured 'em as yet) to be thinner wire for the bottom coil
than the rest, which is both a) odd and b) makes them variable rate or
dual-rate. Funny way of doing it, though, mostly it's done by varying the
helix angle (coil pitch) using a single wire diameter.
no-one seems to have data for what these are meant to be. the free length
of the (identical) pair (pink, red, red) which came off is about the same as
the free length of the longer of the HD90 pair that went on. not quite the
result I wanted - although it's sitting higher than it was at the back, it's
still a tad low compared to the front. I may get tuits to make up a spacer
to go on the axle (which should in theory be a doddle - just needs a
suitable-sized ring of steel with a couple of bolt-holes) and lift it
another inch or so.
quick test run up the road seems to indicate that it's handling OK, within
the limits of the none-too-new standard dampers.
