EV Conversions: Suspension & Weight Tips

The last thing you want after a grueling conversion process is for your new car to have the weight distribution of a glorified golf cart. Weight balance is everything; especially when it comes to having a conversion project that performs better than its previous iteration. Suspension goes hand-in-hand with weight distribution to make your ride glide on the asphalt like a spaceship. We’ve discovered the nuances of EV conversion so that you don’t have to. Let’s dive in.

The Importance of Weight Balance in DIY EV Conversions

Weight balance is the difference between a car that hits corners like it's on rails and one that spins you into a ditch. When you decide to swap out your old ICE engine for some sleek batteries and an electric motor, this is something you have to pay attention to. Normally, ICE vehicles have a front-heavy weight distribution due to the engine’s placement. Converting your car allows you the chance to rethink this distribution and increase the performance of your car even further.

Think about it like this: the battery pack is now the heaviest thing in your car. And because of their modular design, you can split that battery back in two–with one section in the front, and the other in the back. This can significantly improve handling and stability, especially during those sharp turns and high-speed maneuvers.

The Role of EV Suspension

Now, let’s sharpen the other edge of this sword: suspension. Your car’s original suspension was designed for the weight distribution and dynamics of a combustion engine, not a battery pack. When you change the weight profile on there, your stock suspension might buckle.

To adapt properly to the new weight profile, you’ll want stiffer springs, and while you’re at it, upgrade the shock absorbers. Additionally, you’ll also want to consider the car’s intended use. Will it be a daily driver? A performance vehicle? An off-roader, perhaps? Keep these things in mind as they will influence the type of suspension setup you choose.

EV Center of Gravity for Handling

A low center of gravity is your EV’s best friend. Integrating the battery modules into the chassis or floor is one of the best ways to optimize the handling of your vehicle. A lower center of gravity directly translates to better handling and corner performance. While this approach can be more expensive and isn’t possible for all vehicles, it is definitely the preferred method of battery integration. It often requires custom fabrication work, which can increase both the cost and complexity of the conversion.

Despite this, the perks of a well-balanced EV are undeniable. With the added performance benefits an EV already provides, a low center of gravity means better response to your inputs, and ultimately a more enjoyable driving experience.

Here’s the point of all this: if you’re going to DIY your EV conversion, you need to know your stuff, inside and out. Get the suspension right. Balance the weight of your vehicle. The most important aspect of this article is that your project is special. You need to treat it as such. And if you need help from a professional, feel free to submit your project to us here.
