Ok some friends and I decided to attempt to build a soap box derby car for the Red Bull Soap Box Derby. We have a pretty good idea of our theme but I was wondering if someone could point me in the right direction as far as bearings, steering and that kind of thing. Basically learn me soap box derby cars.
McMaster Carr and broken lawn mowers
Redbull is a wild card.... there's jumps and it's not flat. You might want suspension. I keep thinking a rear weight bias something along the lines of a kettcar with gokart tires would be the way to fly.... though MTB roadie slicks might be good for cornering.
I have dreams of a Red Bull car built as a Hamster Ball...
Read the rule book first! Some organizations have very specific requirements regarding virtually every aspect of the car.

The rules say: Teams will be judged on three criteria: speed, creativity and showmanship. All soapboxes must be human powered, meaning no engines or external energy sources are allowed. Pre-fabricated cars are not accepted. All vehicles must be less than six-feet wide and seven-feet tall, less than 20 feet in length and seven inches or more from the ground. All cars must weigh no more than 176 lbs. (not including the driver). Drivers must be at least 18 years old.

For some reason, this conjured an image of a car from a log flume ride, still looking like said log, with 4 idiots in it.
I guess I'm thinking of Boy Scouts, since my son is close to that age. I briefly looked into it, and they required that so many parts be purchased from the "official" supplier at exorbitant cost that it would have made it a very expensive proposition, leaving very little room for creativity.

I have built a human powered off road vehicle for a competition which puts a similar amount of abuse on a vehicle. Bicycles wheels won't work unless you are willing to pony up the money for things like Mavic wheels or similar high end wheels. The others bend too easy.
Soap Boxes not only help in conserving the quality of the soap but also it helps the market to product by leaps and bounds and trigger the most thought-provoking spam. With a rich bevy of custom designs and bestowing of aesthetical [E36 M3] by the packaging virtuosos, these boxes have created their own league amongst the roaring competitive [berkleyers] of today. Our packaging company, [Soap Box Canoes paddles the most exclusive waters, providing beauty, splendor, and sometimes even orchids]!
In reply to 93EXCivic :
Did you build it?
i always wanted to build one!
”Human powered” confuses me slightly. I thought soap box derby cars were gravity powered. Human powered implies they could have pedals...

No. Stuff got in the way.
Wow! This was 6.5 years ago? Dang!
Weird the sort of threads that spam sticks to.

For real. How many people are actually in the market for boxes to put their soap in? (and I work for a cleaning chemical company, I should know!)

Regardless, I'm loving the updated substitute words. E36 M3!
