The trick is to remove the burrs on the nail heads (aka axles), angle the axles slightly so the wheels are pushed out away from the body, and use plenty of graphite powder.
Most importantly in these events, though, is decals. Every good scout knows that the more decals you have, the faster the car will go.
I'm a believer in that too...I'm eyeing some flames for my MCSC

Actually, aero is very important, all other things being equal (polished axles, alignment, and weight). The less drag, the better.

Yes, polishing the axles with very fine sandpaper is a biggie. Smooth the flared (nail head) part of axle that will come in contact with the outside of the wheel. Also, polishing the wheels themselves so that they are very smooth helps to cut friction. And graphite all ovverthe axle, wheel assembly.

My woodworking skills are meager, and my son's car wound up looking like a Scion. Nonetheless, here's Monty in pine.

Nose shape can give you quite an advantage in Pine Car Derby. Go back and take a look at the suggested car design. Having a nose that comes up (having the point of the nose above the bottom of the car) will give you an advantage off the line. I like to get the angle just right so that the front wheels are off the track as the car is on the starting line. It can give your car a 1/8 to 1/16 inch advantage on the line, and totally within the rules. Then polish those axels and use plenty of dry graphite lube on race day. Also get the car as close to the max weight possible. If you use decals put them under a layer of clear coat and then add weight after the paint is on the car.

Look at this piece of work! Not a MINI, but still cool:

I had a great time at the Pinewood Derby with my son. As I recall, my husband ended up leaving me alone with my son as I was getting a bit crazy. We ended up in second place and a great time was had by all. Really, we just kept winning and we couldn't stop laughing about it since we literally forgot about it until the morning of and actually made the thing in like 30 minutes. It still sits up in his bookshelf in a place of honor!
Graphite, we need more graphite!!!

Cool Thread! Our Cub Scouts had a series of races for the GROWNUPS in addition to the kids, which I thought is a cool tradition. So both years we participated, Dad AND son each built cars.
Here's our efforts from 2003, my (fully functional) extension-ladder design in Cub Scout "blue and gold" tones, and my son's ping-pong ball cockpit dragster with toothpick mounted wing .
Note the headlights on J's dragster, it had tail lights too lol, and the abundance of decals (for increased speed, just like his color choice!).
Now I gotta go see if I can find the pics of the surfboard/skateboard cars we did, in 2004!
