Performance upgrades

Micro-Ball Bearings included in this kit decrease the total amount of friction and increase the efficiency of the vehicle by as much as 50-100% over other conventional bushing systems. Adjustable Steering guarantees that the Basic Kit II will travel straight down any hallway; the Basic Kit II can also be adjusted to go in a complete circle of almost any radius.

The Basic Kit II can be assembled in less than 60 minutes for most first time builders and when finished it will travel from 40-65 meters. The Basic Kit II comes with a 12-inch lever arm making The Basic Kit II a good long-distance vehicle without the need for adjusting the lever arm length once assembled.

As with all our top mousetrap racer kits, The Basic Kit II includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.

Micro-Ball Bearings

Micro Ball Bearings are designed to replace the energy wasting bushing systems with a more efficient ball-bearing system that will reduce the total friction by as much as 50-100%. This means that your vehicle will travel up to 50-100% further and faster than the rest of the competition. Micro-ball bearing also decrease the normal wear that occurs between moving parts and helps eliminate heat build-up so your vehicle can convert more of it's starting energy into increased performance. Micro bearings take a little more work to set-up and are intended only for those individuals who want to set a new school record.
