Think about it for a minute and you´ll realize cutting around the runners would be time consuming and very difficult, the result would be dreadful.
The seats have to come out, there will be four bolts or nuts... two front...two rear, centre console too if you have one.
In fact most trim that is over the carpet is best out of the car, you can´t "tuck" carpet, it´s too stiff.
If you get any warm days lay the carpet out to soften, it´ll mold easier to the contours of the floor.
This is a SummitRacing carpet I installed years ago, it is still in very good condition.
Yes, those dreadful floormats were binned.
But with the bolts in place, you'll know exactly where to cut a hole and make re installation a lot easier.
