Questions re: Tender Springs with GC Groundcontrol Coilover Conversions
I am going to be installing some ground control coilver conversions on my 3000GT VR4 and I know some of you will scoff at the idea, however, I'm on a tight budget. What I'm wondering is has anybody subsituted in their own combination of main spring and tender spring? Or has anybody used progressive eibach springs?
On Jeff Lucius's GC install page he recommends using:
6" length/2.5"I.D./500lb/in in front and 8" length/2.5"I.D./360lb/in in the rear.
So, in choosing tender springs, should the height of the tender spring + main spring = 6" in front and 8" in the back? If so, then that creates a problem. The shortest 2.5" I.D. main spring eibach makes is 6".
I know some people have complained these height of springs loose contact with the top of the strut base when the wheels are at full droop (off the ground). Could this be fixed by using tender springs, or would I need to have helper springs as well?
Any help would be greatly appreciated.
