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.
