The stock mud flaps for Punto is horrible and i couldn't find any good alternative. I am just thinking to remove it and leave it like that. So wondering, is it must to have?
Check your side sill at the front of the rear wheel arch (at the corner where the wheel arch meets the side sill)
There will be a clear transparent tape stuck there.
This is to prevent paint damage from stones thrown up by the front wheel.
It is now commonly seen ... Swift, Fabia etc.
The Front Mudflaps are critical to prevent stone chip damage, this is inspite of the the preventive measures taken by most manufacturers.
The rear ... like some others have mentioned, are for the bikers behind, and a bit for your bumper.
Most OE Front Mudflaps are pretty decent, and anyways are not that visible.
The rear mudflaps are more commonly "fugly".
You could do what I have done ... I have only the front mudflaps fitted, and the rear is bare and beautiful!!
