So, I owned an open wheeled kit car. An NG TC.
Over the rear wheels, sit large mudguards, as smiliar to 1000's of UK kit cars out there.
The fronts of these mudguards are covered in a carbonfibre panel but still littered with stonechips, which again, seems to be the norm.
I can't see the point in the mudguards being present in front of the rear wheel.
On front wheels, mudguards typically start near the top of the tyre at the front and curve around the back of the tyre, to lessen mug, water being flung up behind them.
On the rear though, the mudguards tend to cover the front of the tyre. Why bother? Will mud and water get flung forward from the rear wheel without it?
Help me understand before I take a hacksaw to the wing to tidy the whole thing up. It nevertheless gets driven in the rain anyway.....

If your a cyclist, and cycle with mudgaurds in the rain, you will know why.

In the rain the tyres kick up enough water, at a high enough speed to flick a surprisingly large quantity of water forwards. Most gets flicked up and hits the inside of the arch, then runs off the back, but a lot will get flung forwards too with the velocity of the wheel.
Makes sense, thanks. So, if I will only ever get caught in the rain on the odd occasion I may cut the arches as I think it will look better.

Not sure the long rear mudguard is that esential to void debris being thrown forward.
As long as there is some protection along the top of the wheel, I would have thought that very little will get thrown forward.
The one car that has the type of set up I am suggesting is the Ariel Atom. If they drive around like that, gives me more faith that there won't be any real problems.
