A simple, yet fun mousetrap design can be incorporated into a wide variety of car designs. Here are just a few things you can try:

Ways To Modify A Classic Car Design

There are many ways to modify a classic car design, but the easiest way is with a mousetrap car design. Start by drawing your car in a paper design, making sure to list the wheels, tires, windows and everything else. Draw a line from the front door to the back door, noting where the two meet. Form the line another way, cutting it just slightly on either side to define the width of the track.

The next step is to decide what kind of suspension you want for your vehicle. You can either have a conventional set of springs or you can use a system of air-filled shocks and hydraulics. The idea behind both types of suspension is to provide a smooth ride and minimal handling. To get a better idea of how a mousetrap car design works, check out the YouTube video referenced below.

Remove The Existing Wheels And Tires

If you want to use a conventional set of tires on your vehicle, you will need to remove the existing wheels and tires. Remove all three wheels so you can easily see the spacing between the axles. Line up the new axles to the current spacing, making sure they are straight with your mousetrap car design. This is important because the spacing is the basis of the weight distribution. Now it’s time to bolt on new tires onto the vehicle.

The reason this system is referred to as a mousetrap is simply because the tires aren’t lifted off the ground like conventional tires are. In other words, you can’t just put a normal tire on a mousetrap – you need to make room for your new suspension by stacking your car on four tires. When you take out a conventional vehicle and bolt them onto a flat bed, there is only room for one or two tires. With a mousetrap car design, you can lift the entire vehicle so you’re basically putting three cars on one bed. This means a much smoother ride for the driver, as well as reduced steering angles, better handling, and a reduction in wind resistance.

This doesn’t mean you can’t qualify if you have poor maneuverability or the ability to accelerate and decelerate at a faster rate. In fact, the system offers adjustable damping so you can tweak each of the components individually for each situation. For instance, if you start out with ten points and your speed starts off at forty Kph, then you can set the mousetrap car suspension to adapt to different starting conditions. You’d adjust the spring rate until your speed starts out at twenty Kph and then slow it down. This will ensure that you don’t get a surge in speed when you hit the start line.

Smooth Torque Curve With Zero Lift

With the proper components, you can create a smooth torque curve with zero lift, even at the maximum compression. This results in smoother power impulses and allows for accurate mapping of the displacement transfer. To perform this mapping function, the mousetrap uses a hydraulic arm and spring system. The arm acts as the large spindle on which the piston or cylinder rotates, and the lower spring optimized for displacement transfer is mounted under the piston.


If you are new to the concept of suspension, you should first learn how to calculate the damping forces by using a spreadsheet. Then you should modify your spreadsheet to use the displacement and the torque of each of the components and add a third force called the creep force. By adding the third force to the torque and the displacement you’ll get your creep force. Using this force you should map the transfer of the torque and creep to the axle. This technique can be used to map the axle to each of the wheels.
