Ok I finally this past W/E was able to finally adjust the shock.
AFCO 10” Spring Installation
360/430 Front Spring Installation
The AFCO replacement spring for the 360 front suspension is an AFCO P/N: 23400. It is a 400# spring and it measures 10” in height. The OEM spring is 9.5” +/- in height, and it is about 350# in pressure. The P/N: 23400 AFCO is about 15% slightly greater in pressure which gives the front end just a bit more control, less sway, and takes away the slight dip at speeds.

The final vehicle height adjustment process can be done easiest with the shock body mounted in the spring compressor. It can certainly be done with the spring mounted, but it is much easier to do it with the spring compressed outside of the vehicle. See 360 Front Shock Removal.
Have a knowledgeable person compress the springs on a quality piece of equipment if you are not familiar with spring compression. It is a dangerous process for a novice!
Remember that prior to removing the OEM spring one must measure the original location of the spring support collar to a fixed point on the shock before removing the OEM spring. Mark with a small felt pen on the shock body and record the distance on each shock. You are measuring from the bottom of the spring support collar to any point on the shock for a reference point! When installing the new AFCO spring you will then have a reference point to drop the additional required ½” on the spring support collar.
There is a ½” height difference between the OEM and the AFCO spring, and then, and when the AFCO spring is mounted into the coilover the spring supporting collar (measurement) must be lowered by this ½” amount to equal the original spring distance.
The additional pressure of the AFCO spring will raise the vehicle about 1” when the spring support collar is dropped the additional ½” from the OEM location on the shock body.
When the factory spring is replaced with the AFCO spring and adjustment will be done with the shock assembly mounted on the vehicle, one must refer to the Motion Ratio table for additional turns.
With the spring in the compressor and with the support ring set to the OEM spring distance above-marked, there are approximately 16 additional turns required to lower the spring support ring so that the vehicle will settle to factory settings. This is based upon the OEM springs set to the OEM Ferrari ride height.
See “Lowering A 360/430” for the procedure and preferred tools.
When the adjustment is done with the spring in the compressor, turning the spring support ring is easy.
Again, mark the OEM distance of the spring support ring on the shock body before spring removal, compress the OEM spring, loosen the locking ring and remove, slowly loosen the spring support ring until free, remove the spring, install the AFCO spring and compress, reduce the distance you measured for the OEM spring by ½” (12.5mm) and then set the spring support ring down 16 turns from there. Lock the rings and slowly decompress the spring.
Check the lower shock support bushings before reinstallation and replace if necessary. This is important as they may knock. They are Ferrari P/N: 157630
Upon installation of the complete coilover assembly the front body height should be exactly as prescribed in the “Lowering A 360 or 430” discussion. Check the measurements from below as prescribed by Ferrari, and adjust as necessary.
If too low (which they should not be) one can always turn up the ring to raise the vehicle. See the M.R. chart for the effect.
