To strip or not to strip, that is the question....

[impotentials]

So the time has come to decide if I stick with the original plan of making a shiny neat car or go a little more speed conscious. So do I remove all the rear seats, carpet etc and lose a few pounds. Keep the front carpets, head lining and door cards. Then get some buckets and a new stearing wheel. Or keep all as is. Stock if you like. I assume losing a little weight will still be noticeable? Certainly a difference when I put a fat man in the car as a passenger. 

Opinions please.....
