Accel Fenders for Pinewood Derby Cars

Click Here to Order Accel Fenders

Aero Fenders are 3-D printed, plastic fenders that are pre-shaped, and lightweight (lighter than balsa fenders), making it easy for you to get more speed and a cool look. Just lightly sand, glue them on with epoxy, and paint (or paint separately for a two-tone look).

The Accel Fenders are hollow with an access hole. So if desired, tungsten putty can be placed into the rear fenders to get more weight on a lightweight car.

Fender Weight

Accel Fenders are lighter than pine or balsa fenders:

  Accel Fender Pair: Front-1.1g, Rear-1.3g

  Pine Fender Pair1: Front-3.1g, Rear-3.8g

  Balsa Fender Pair1: Front-1.3g, Rear-2.1g

1Estimated weight assuming typical shaping.

Aero Fender Instructions

To use the Accel Fenders:
  • Lightly sand the fenders.

  • If a two tone look is desired, paint the fenders separately from the car.

  • Temporarily install a wheel/axle, position a fender to allow clearance for the wheel, then attach the fender with epoxy. Allow the epoxy to cure, then repeat for the other three fenders.

  • If the fenders are not pre-painted, paint the car.
