Ready to upgrade the handling of your 451 model smart?


The MADNESS Lowering Springs were developed as a joint effort between us (MADNESS) and our European Partners that produce some of the best performance spring in the world for your 451 model smart.

We confidently say that we have installed more suspension upgrades for the smart then any other company in North America. While we offered a number of lowering spring solutions we were not satisfied with the results. Rather then compromise and settle with the limited selection of what was available we decided to design and produce our own MADNESS Lowering Springs. The springs were designed to not only lower then car, but improve the handling of the vehicle while not drastically altering the ride quality. 


We designed the springs to be progressive rate for the best combination of ride and handling. What are progressive rate springs?

Progressive rate springs feature individual coils that are spaced differently and have a spring rate that is variable. Under normal driving conditions the first couple of centimeters compress easily, but as you apply more force (as in high speed cornering) the coils come closer. At a certain point, coil at the top 1/4 of progressive springs begin to touch each other and finally become inactive or dead, and that makes the spring stiffer. Apply more forces to a progressive spring then it becomes stiffer because as the number of active coils in a spring decreases, the spring rate increases. So, progressive springs may both be sensitive to very small bumps on the road, while giving the stiffness you need during hard braking and turning.

About Manufacturer

MADNESS Autoworks is your One Stop Shop for customizing, accessorizing and servicing your favorite ride.

After spending over a decade customizing countless vehicles and working with many local and international suppliers we have been fortunate to be able to offer a very large inventory of products to our fellow enthusiasts. However, at times we have found that what was available was not good enough or perhaps other options were also needed. When this happens we either design and manufacture the product ourselves or tap one of our manufacturing partners and ask them to assist and make a product to our specs.

Over the years that we have been in business we have formed a number of partnerships with our most trusted manufacturing partners and suppliers to help us produce products that we felt were needed and not available. At times we have also invested in infrastructure, manufacturing equipment and have recruiting some of the best talent that could help us design and build superior products and make them available to our fellow drivers.
 

Our goal at MADNESS is to provide top quality products that has been tested and used in our own vehicles and have proven to last and provide a good value for the investment. We do not design and build our products to be the cheapest, we design then to be the best value for the money and stand behind them the same way we stand behind our work.
