cracked undertray

[Andp]

The undertray has a large crack going sideways, which as I regularly have to drive down a potholed private track, collects a lot of stones
- that have an alarming habit of flying out at speed when I return to normal tarmac.
Just thinking whether it is worth replacing/repairing tray as the likelihood is it will may well get damaged again, or leave as is?
Could the stones cause any damage to the underneath of my Zm roadster?

Any views gratefully received.

When I bought mine...after losing half of it at the Nurburgring...I paid about £190 (delivered) for a genuine one (51717895804).

Looking at the same vendor Schmiedmann), it seems to be £223+postage now - or €233 at Leebmann24

It's listed at about £250 at a UK dealer, so with a bit of negotiation I'm sure you could get it for less than the 'imported' part.

Don't know if there's an aftermarket copy available - in fibre or ally.
