Why don't you just gut the whole back portion of your coupe? Seat, seatbelts and all.

Then you'll have a good excuse for all those "hey dude, lemme get a ride w/you guys" freeloaders.

I've found that after I did that w/mine, when ever I wanted to go on grip runs, I would have to throw a couple of tires in the back.
