or they could used good engineering practice and use flexible lines....... instead they choose to save a few pence and compromise the safety of owners and other road users.
.....god only knows why SVA / IVA allow them to pass, especially considering how padantic they can be on trim radii and plastic covers -
Resurrecting this old thread, does anyone know if the possibly short hoses, if one has the watts linkage, issue has been addressed? Are the hoses supplied by Redline still borderline? Does Redline supply a full kit of parts to do the conversion and does anyone know the approx cost?
As I understand it, the Redline supplied hoses are longer than the ones CC supply.
There are flexible hoses for S3 and S5 cars here at Redline, we spend a good amount of time getting the lengths correct

When I fitted the flexables from redline I made up a bracket as in this picture.flexible
I have been seriously considering changing to rear flexi hoses this winter. I would rather leave the bulk of the solid pipe attached to the de Dion & three way connector just having short hoses similar to the front hoses connected outboard from the rigid pipe to the caliper.
To me that solution looks more elegant & it is the same sort of thing I always found on aircraft.
I believe there was a parts list about for that type of mod. It is just the thread & size spec for the connector at the caliper end & same at the inner hose end. Any one have info on this?
Either way up access is a slight issue but there are so many 'widgets' about (drill extensions, in situ pipe flaring tool) that it should not be too much of a problem.
I think your proposal is a very neat idea.
The CC hoses I used (S3) came from Goodridge. The short one (77201L) looks like this, but both short and long have the same connectors:
At the calliper end:
Adaptor (1/8” BSP to M10 x 1.0)
This connects to the hose via a swivel fitting (-03 hose, 1/8” BSP thread):
Then, at the 3-way, there's what Goodridge call a "bulkhead" fitting (-03 hose, 3/8” x24 UNF) -- like this but longer:
Hope that helps!

I fitted CC-supplied S3 hoses to my R400D (with Watts links). They were long enough, but I was concerned about how to prevent the hoses rubbing against the de Dion brackets. One neat solution was to fit 45-deg elbows to the callipers. I ended up fitting rubber sleeves (similar to Blue C7 in #26).

Solid pipes at the rear do not need to move a lot. Hoses will need to be replaced periodically. I would guess that a rear hose is more likely to fail than a pipe.
