Took me a bit longer then it should, but anyway, here they are.The second pic is upsode down, but it's clear to see, that the spring in held down by a bolt that goes throuhg the spring arm. At least mine is.
BTW: CG Trading's springs and bolts are diff. than "original" equipement. In his case the springs can be lowered ang raised if I'm not mistaken (to put it another way: the whole car can be lowered or raised, which isn't possible with standard springs or eibach/novitec springs).
sorry but you are misunderstanding our expanations.
The bolt in your picture probably is securing the lower bump stop 'plate' which normally just pushes through the springpan, this is holding the spring in place but isn't normally there on a standard set up.
Your earlier post showed a bolt circled green, this is the only bolt you need to remove to remove the spring. Undoing the shock or shock arm makes replacing it easier.
Some of my earlier pictures showed a non std adjustable FK set up which does have a bolt to locate the alloy adjuster, the other pictures show std components.
If I only had 1 car then I could obviously be wrong but currently I have 18 GTV/Spiders, most of which have std suspension. I do have lowered set ups, Konis & one with FK coilovers that has adjustable rear springs like the pictures. Also I fit these myself & have spare springs, springpan arms, bump stops etc etc.
Pictured below are yellow & red lowering springs which use the std fittings but the blue is an FK adjustable.
Like I said, I think you're just misunderstanding me/us?
