I have been in contact with a few friends from the West Coast who told me that some of the guys were running a sedan shock on their F104V2 cars with a long shock end and the shock mount set up for the small shock that comes with the car. At first, I had it set up the wrong way, which requires you to space the mount up to clear the upper deck/brace. Here is what the correct way looks like:
I tried it on the track back to back with the "normal" sedan shock set up. It seems to make the car steer more "directly". I'll have to play around with it a little, but if nothing else it did not hurt the setup, lap times were pretty much the same.
