Pinewood derby car with either BSA slots or Drilled Extended wheel base (your choice)

• Weighted car to 120-124 grams (very close to final weight of 5oz)
• 4x BSA Wheels –machined, lathed and sanded– ready to race
• 4x BSA Axles– deburred, shaped, straightened, and polished –ready to race

 

 

8 reasons why our kits are better!

 

Here’s a side by side comparison of a “purchased” car that was ready to race. Red/Blue car is theirs, bare wood is ours.

#1 How many kits come weight balanced? Our cars are perfected balanced for speed. Weight balanced ½-1” in front of rear axle for maximum potential energy. Does it matter where the center of gravity is? Absolutely! Our bodies are brought up to 124 grams of weight. With 3 light coats of paint and a regular set of wheels and axles this should be extremely close to 5oz. Additional add-ons may cause your car to be overweight.

 

Red car is theirs, bare wood is ours.

#2 To help correct over steering or wheel wobble, we have reduced the wheel base on the front end just slightly. This is one of those speed tips that is easy to explain, but hard to do with a hammer and chisel. If you take out too much, then your car will rub the entire way down the track or you have to over-gap your wheels to correct the problem. The perfect depth is 0.10” inch. It takes a milling machine to do it right. Take note, some packs might not allow this modification.

 

Blue car is theirs, bare wood is ours.

See the competition’s blue body! It can be done better! Derby Dust offers this with most body styles!

#3, #4 We reduced the surface area at the body that could be a potential speed robbing point. As seen on the Red car where the wheel rubs as it ran down the track. Our inner wheel hub area has the most amount of wood removed to reduce surface area for friction while maintaining structural stability. We also remove the area of potential rub on the outer portion of the wheel. Since the wood is removed, there is nothing to rub!

Red car is theirs, bare wood is ours.

#5 Our wheel set is machined by one of the best in the industry. Wheels are the new 2009 mold. They turned to same diameter; high spots are milled off; and then sanded to hide any milling marks. All BSA lettering are left alone. Wheel crimps (tread) are still visible. This set will pass the most picky of all inspectors. Upgraded (lighter wheels) are available which will increase your speeds. Check local rules before upgrading.

 

#6 , #7 Axles. The axles are like the engines of the derby car. Without the best possible axles, do not expect to place. Our prepped have been deburred, shaped, straightened and sanded down to a 1000 grit finish. In addition, the head of the axle has been cut to a slight taper to reduce the surface area which decreases friction! Then buffed to a fine shine! You can't even buy 2 of the tools needed to do this for under $25. Much less the files sandpaper, and buffing materials.

#8 Our bodies are low profile in front with larger profile in back. What does this do? It has to do with aerodynamics and decreasing drag. We don’t waste your time with big bulky cars!

#9 Most of our bodies utilize a quick start front end. By having an upward tapered front end, this allows your car to release from the starting gate sooner than if you had a lower tapered front end. It sounds crazy, but your car could start down the track before the others!
