The shocks are wound into the bodies as far as they'll go. With the spring perch applying a slight amount of preload to the spring, the perch still sits about 5" higher on the thread than the locking collar on the body. That's the absolute lowest it will go without shorter springs, agreed? When the bodies are wound completely down and the spring is under minimal preload?
The pictures above, i've dropped the perch all the way down the threads to compensate for the lack of weight in the engine bay (250-300kg missing) to get the stance I want. If I wind the perch up to where it should be at the "lowest" setting mentioned in the last paragraph, the ride height raises by the same amount. Once the weight of the engine is in there, I guarantee the ride height will not drop by that 5" or so again. A 6.5" main spring at 400lb will NOT compress to 1.5", no chance. So the ride height at the coilies' "lowest" setting with a fully assembled car will be an inch or two higher than what you see in those pictures.
What i'm saying is the lowest setting on these springs won't actually be as low as it is now, not that I can make out anyway.
So do I drop the spring perch a few inches to lower the "lowest" setting and fire in, say, a 3" helper spring to stop the main spring unseating?
