Do you run with the front arch liners removed?

[Kroggers]

I am permanently looking to reduce weight and improve the Boxster racing car.

I recently removed the rear arch liners on the car, as I was having rubbing problems, and I did not see a reason to retain them on a racing car. To ensure I do not get a build up of air and additional drag behind the rear bumper with the liners removed, I opened up the rear bumper - giving clear air flow. I also hope this will help a bit with cooling

But I have now started to look at the front liners and I am wondering if I can also remove these, and if it will give any benefit to do so?

I will be removing the head-lights and replacing them with fiberglass covers, so I do not need the liners to protect the rear of the lights - but what else will I put in danger by removing the liners?
