Wheel Arch Liners on Trackdays

I think I have a full set with no major rubbing.

I have kept them on the car as it is still gets used from time to time on the road.

The ride height on my car might be slightly higher that others?
 
Thanks all.

I'm in the category of running what is left currently and wondered if it worth getting new? Take it isn't?

My only concern is running the car on the road and exposing belts etc.
