After a recent service we were told that our '99 xkr was showing signs of rust around the underside floor area on both sides.
The mechanic also said there were two triangular plates that look like they were welded in at manufacture and he thought these would need to be replaced but he knew nothing about it.
We have tried to find out more but with little sucess.

Anyone with any experience of this? Possible solutions? Can the plates br bought?

Thanks to all
