Construction Rules – Minis & Hotrods

  • Kamtec Mini Racer
  • Mardave Mini Assassin
  • Mardave Mini Racer S

A car may use different parts from each kit, but must have these parts mounted in the same position as the kit it was sourced from.

Mini Bodyshell

Lexan only, from the following list:

  • Mini Classic

  • Kamtec Hot Rod
  • Mardave VRX OE/OES/OESC

A car may use different parts from each kit, but must have these parts mounted in the same position as the kit it was sourced from.

Hotrod Bodyshell

Lexan only, bodyshells should be based on a hot-hatch type car.

Examples:

Most Important Rule

Have fun!

This is not a class designed to be for serious racers. The rules are open enough to allow drivers to run what they own, without having to spend a fortune on new parts just to be able to compete.

Inevitably there will be a little bit of contact between cars while racing, as long as the racing is kept to a clean standard then there will be no problems.

If you see a rule that doesn’t look right or needs a clarification, do not hesitate to mention it to the committee and we will look to resolve it in the most fair way possible.
