Can see all sorts of headaches with the idea of arches.
- Firstly, there is the question of the impact on aero - could the arches make it harder to overtake again for example?
- Then there's the question of where the spray comes from - realistically how much is from the tyres themselves?
- If a large percentage of the spray DOES come directly off the tyres now - does fitting wheel arches mean that spay will now be directed back onto the tyre and track surface - meaning less clearing of the track due to cars running, more risk of aquaplaning and maybe overloading the tyre's capacity to deal with water.
- Then there is the question of attachment methodology - if fitted during a race won't be scrutineered so is there surety on how safe - also, will the arches deal OK with impacts from other cars or are they likely to fly off easily?
No doubt there are many other things to consider as that short list is straight off the top of my head on first thought.
Sounds like a thought bubble that hasn't been really examined so don't know how serious they are.
