I totally agree Gentlemen. (Ok..I'm bein nice today
)
As Mike said, the archives contain heaps of history about failures, some catastrophic (sp) of failed Jag rear ends.
Whilst in the Jag ( a much heavier car) it is all rubber mounted. All that rubber does is wash off some of the stresses. In the cobra we solid mount them so that stresses are immediated and not cushioned. Not a good thing in my book.
Also on my RMC the coilovers are mounted about 70mm either side of center of the swinging arm. This to me would increase any twisting forces applied to the arm in the case of a single coilover system.
The case that RMC did (in the later part of their involvement) use single coilovers, I'm not convinced that is a valid reason to do so.
I make reference to the fact that RMC front top suspension mounting points were twisting off is sufficient justification to suspect any manufactures recommendation.
CWI also make a tubular moly swing arm for the Jag. I don't know if this is any stronger than the Jag setup but it is said that trailing arms are not requited for this setup.
