RRS vs D3/D4 shock lengths etc?

[Graeme]

Does anyone know if there are differences in open and closed lengths and airspring seat heights between 2007+ RRS & 2007+ D3/D4 shocks? I suspect there are because D3s and D4s appear to be able to go lower than the RRS but would like to know for sure.

I wasn't aware of any differences other than the cars fitted with the Dynamic Pack.

Have you compared part numbers to see what is different?

I haven't compared part numbers but would expect different part numbers for different valving.

My interest is in whether the variable rate dampers would or would not restrict normal D4 suspension movement.
