Aeromods on a brick - impressive.
Keeping them discreet -priceless
I admire trying to squeeze even more km out of each litre of fuel, especially if you are already doing well.
You seem to be keeping the mods out of sight - Is this because the car has antique status? Or is it to avoid potential problems with police/legalization?
Another mod I would recommend is a grille block. It helps both aerodynamics and improves engine warm-up (and is great when paired with insulation and an engine coolant warmer!).
The grille block can be made clear, and can open/close if you are worried about overheating.
