Duning is all about turning.  90% of the time you're turning to negotiate the terrain, transitioning between bowls, avoiding obstacles, or spinning on a dime for thrills.  If your car understeers or "pushes" in the sand you’ll be fighting for control, making work out of your play.  Good handling is key to having fun in the sand, and having a sandcar that handles good with 5 passengers as well as 2 passengers is what you want.  But interestingly enough, most people have never experienced a good handling sandcar.  They think that all cars handle about the same, which is far from reality.
We concentrate on making our cars turn well in addition to soaking up whoops. Funco has achieved an ideal 35/65 weight bias ratio front to rear with typical passengers.  The front seats are placed in a cab forward design, moving the weight bias forward.  While moving them forward we also positioned the passengers more upright, allowing legs to be pulled in.  As a result of pulling in the legs this allowed us to shortened the wheelbase to 117-122" without stealing legroom.  And due to a shorter wheelbase this improves the turning radius to provide a quick steering response, resulting in a very nimble car while hauling around 5 passengers.

In summary here's how we achieved our ideal 35/65 weight distribution ratio:

1.  "Cab forward" design puts more weight up front

2.  Upright seating helps to move passengers forward, not to mention it improves visibility and comfort.

The proof of our handling is in the driving.  Good handling in the dunes is truly possible in a 5 seat car.  The other proof, you'll almost never see a Funco car using razor front tires to prevent understeer, simply because they aren't needed.  Funco uses durable farm implement tire to maximize floation and minimize sand getting thrown into the car.  Our implement tires can also be very convenient if you want to go on a desert a trail ride, alleviating the need to swap front tires, implement tires work great in the desert hard pan dirt.  

Whether it's NASCAR, F1, IRL, or CART, race car designers will tell you the “laws of physics” say weight distribution is a key element  to a good handling car.  Without the weight being distributed to all 4 wheels properly the suspension and steering geometry cannot work in harmony, allowing the car to go in the direction it's steered.  At Funco we have found the same “laws of physics” to be true with sandcar design.  Weight distribution and center of gravity highly affect a sandcar's behavior, that's why we pay so much attention to weight distribution.
