So I'm spitting my dummy out about this side repeater nonsense. The IVA manual needs rewriting here as it's fairly ambiguous, but aparently they should be able to be seen between 5˚ and 60˚ from the direction of travel from the rear but also vertically between 5˚ below and 15˚ above. All of this isn't really a problem apart from the 5˚ below which in a car as low as ours is damn right dumb and causes a problem due to the rear wing unless your happy to fit a side repeater to your front or rear arch.
Whomever needs to see my side repeater from 5˚ below a car no higher than 750mm is a dead man as he's almost lying on the floor in the middle of the road. Unless we now have to take into consideration dogs and toddlers.
But anyway I think I found a suitable yet unusual position. Call me mad but you can see the corner of the scuttle/dash from this viewpoint.
5˚ out and below
Proposed position
60˚ out
If anyone knows of any reason why this is a nono location please let me know.
