Dude - that just makes it lighter. Lighter = faster.
After one particularly epic party that involved a set of hot twins from Powers, we did a Taco Bell run. Part had a mid 70's Ford that had no floor boards. Well it did - basically had a 2x6 from the trans tunnel to the outside rocker panel.
Wish I woulda taken pics. The run into Esky was only 20 miles but it was 3am in January. The 40 mile roundy was about the coldest I've ever been in my life.
