I respectfully disagree. If you hit a rumble strip and get a wheel airborne (fairly common on track), and the spring becomes un-seated from the top hat, your car will not drive the same. If your spring is not touching your top hat at full droop, then you need helper springs for sure.
What length springs are leaving space at full droop? Those are 7" or 8"???

Many times the sway bar can help keep the damper on the air-borne corner from extending too far.
is the koni strut used for gc coilovers different in any way i have a set with h&r springs but wanted to upgrade to ground controls someone said there was a thinner koni for gc's
yes, to use the ground controls you have to get the koni shocks specifically made for them.

I also went from H&R Sport to GC's. You just get the Koni-specific GC's which fit directly on the Koni snap ring. You do not use the Koni spring perches when you install the GC's, as shown in my pics above.

Its the Koni Sport (Yellow) and Bilstein HD shocks that use a different GC mount.
More or less. Only difference is that you put the sleeve on top of the lower spring mount. With the Konis, you leave the spring mount off and place the sleeve directly on the circlip.

Are you sure about the Bilsteins? Their site says +$40 just like the Konis so I'd expect them to be different.
I believe the edge of the dish would dig into the bushing and cut it over time. You want the flat surface in the center to give even contact without damaging the bushing.

Because that's how they're designed?
This is a logical answer. But yeah they face up because that's how they were designed to be oriented.

The left-most end of that sheet shows the adjusting procedure for externally-adjustable Koni shocks, such as the yellow Koni Sport shocks. The 1, 2, and 3 diagrams show the procedure for adjusting internally-adjustable shocks such as the red Koni Special shocks.
That sheet is not showing any assembly instructions.
What do you need to know?

I got the Koni yellow's and I thought it was going to be a simple install. Although when I saw steps 1-3 I was confused on whether I have to do any adjustments prior to strut assembly.

I believe certain applications of the Koni Sport are actually internally adjustable and not external (older Corvettes or something if I recall), so those pics are probably for those shocks.
