Not sure where to place the fire bottle (it’s tiny!), battery and cool shirt system(yet tbd).
Thinking the cooler will go where the passenger seat mounts.
Battery and fire bottle have wires & tubing to run. Along the sill would be cleaner than runs along the tunnel. Some pictures for consideration.
My last helmet was painted – by me – and I enjoyed the process. The design was nice and could have been better executed but I was pleased with the result. Unfortunately, the helmet expired (SA2005) and the new has a 10yr life span (SA2015); it will have to look even better than the last.
With the car build moving so slowly and ready to accelerate hard with short notice, outsourcing the helmet paint is looking more attractive.
There is a large collection of helmet images saved to my personal collection over the years as considerations or inspiration: some for colors and others for designs that I find attractive.
These images illustrate my expired helmet and short list of favorites from the collection.
