Specifications for Block and Kits

Standard Wheel Base Slots
The blocks and kits with standard wheel base slots are machined to duplicate BSA standards for axle slot placement and dimensions. Thus the:
  1. Axle slot placement meets BSA standards.

  2. Axle slot width and depth meets BSA standards.
Standard Wheel Base Holes
The blocks and kits with standard wheel base holes are precision drilled to duplicate BSA standards for axle placement. This has the advantage of simplifying axle installation and alignment. Please note that axle holes are not allowed in many races. Check your local rules before choosing this option.
  1. Axle holes are drilled with a #44 bit - best for BSA axles.

  2. One front axle hole is drilled slightly higher so that the car only rides on three wheels (best performance).
Extended Wheel Base Holes
The blocks and kits with extended wheel base holes are precision drilled to maximize the wheel base. This has the advantage of simplifying axle installation and alignment, and allows for better weight distribution. Please note that extended wheel base cars are not allowed in many races. Check your local rules before choosing this option.
  1. Wheel base is 5-3/4 inches - the maximum possible for 1-1/4 inch diameter wheels. Thus, each axle is 5/8 inch from an end of the block.

  2. Axle holes are drilled with a #44 bit - best for BSA axles.

  3. One front axle hole is drilled slightly higher so that the car only rides on three wheels (best performance).

Standard Options

The following standard options are available. Please make sure to select a kit or block before selecting an option.

  1. Drilled Axle Holes, 4 Wheels On The Ground - For best performance, kits and block with axle holes are equipped with a raised wheel. If you prefer all wheels on the ground, select this option.


  2. Extended Block/Kit w/ Standard Slots - In some races, an extended wheel base is allowed as long as the original axle slots are present. Select this option if you want both extended holes and standard slots on the same block.


  3. 3/32 Inch Axle Holes for Awana or Bearing Axles - Kits and blocks with axle holes are drilled with a #44 bit. This is too small for Awana axles and our Bearing Axles. If you plan to use Awana or Bearing axles, select this option and the holes will be drilled with a 3/32" drill bit.

Custom Work

 (Custom kits and work may not be available during January, February, and March)

We do not sell completed cars, however, we do perform custom work. If you need a non-standard modification to one of our blocks or kits, please Contact Us describing the desired modification in detail. We will reply with a quote for the work and the estimated delivery time.

We also provide many of the car designs from our car plan booklets as a custom kit. The kit includes the pre-drilled and cut car body, weight, and instructions. Wheels and axles are not included, and except as noted below all body curves must be applied by the builder.

For the custom kits below, the standard wheelbase version is equipped with axle slots that conform to BSA standards, while the extended wheelbase version is equipped with axle holes, and the front left wheel is raised 1/16 inch. If you want a different axle configuration, please Contact Us.
