Having some inspirational thoughts about my possible failures and potential solutions.....
1. Something to do with the handbrake or rear brakes that I can't sort on the day.
Can't fix this as it is not broken. So put this down to paranoia.
2. I have protected well but not grommeted the wiring coming through the bulk head.
Going to cut the scuttle slightly larger around this wire with a dremel and glue fit rubber trim!
3. Front indicators are too far from the widest part of the car.
If this is an issue I will remove the indicators and fit stalk indicators the the side of the indicator pods!
4. They don't like the radius edges of the modified caterham hazard and fog switches when in use.
I measured the hole and the projections and it only needs to be blunt not radiused which they are.
5. They don't like the stick on side repeaters on they aren't bright enough or too low down.
I've ordered some others that should be IVA OK which I will fit on the day if need be.
