Top 4 Best Coilovers for Chevrolet C6 Corvette

Most generations of the Chevrolet Corvette have had enormous success. Its power ratings and its performance can easily beat its European counterparts – for almost half the price. However, no matter how impressive the Chevrolet Corvette is, notably the C6 Corvette, it still has a somewhat controversial issue.

Most of you may already know this fact, but the Chevrolet Corvette C6 still uses an ancient suspension technology – the transverse leaf springs. No matter how feasible transverse leaf springs are, it still draws flak, especially for car enthusiasts who have owned or currently own one with a coil spring suspension.

There’s no doubt that, yes, transverse leaf springs work impressively well. General Motors chose this type of suspension for several acceptable reasons. But no matter how viable the transverse leaf springs are, they still can’t handle twists and turns effectively.

The C6 Corvette has problems with cornering and body roll, which are detrimental for competitive drivers who love track and street racing.

These are just some valid reasons why Chevrolet Corvette C6 owners opt for coilovers instead. Coilovers can compensate for the handling issues present with the C6 Corvettes with fiber-reinforced plastic transverse leaf springs.

Not to mention the freedom of tuning and suspension customization that these puppies can deliver to racing fans.

Below are some of the most popular C6 Corvette coilover kits for drivers who want to keep their cars on their competitive edge.

If Leaf Springs Are Viable, Then Why People Convert Their C6 Corvettes to Coilovers?

It’s fantastic to see an antiquated suspension technology still used up to this day. General Motors did see the potential of leaf springs when they used them in the first Chevrolet Corvette.

As a result, almost all of the generations of the Corvettes have fiber-reinforced plastic transverse leaf springs, except the latest C8 Corvette, which finally transitioned into coil springs.

There are two main reasons why General Motors chose leaf springs over coil springs for the Corvette, specifically the C6 Corvette.

  1. Leaf springs function well. How many cars do you think can handle better than the Z06? This kind of suspension system can cope much better with vehicle damping, thus making the Corvette easier to control.
  1. Leaf springs are far cheaper to manufacture than coil springs. One of the criteria that makes the Chevrolet Corvette such a blockbuster is that it’s more affordable than its European sports car counterparts. It only makes sense to use a cheap suspension system effective enough to provide the exact top-tier handling that you can only find on sports cars.

Surprisingly, leaf springs are still a viable suspension system for a performance car, even though they’re over a century older than sliced bread. However, there’s a growing trend where many C6 Corvette owners decide to convert into coilovers.

Why do you think that is? It’s because leaf springs have a fatal flaw: they’re braindead when it comes to suspension tuning.

As a car enthusiast, you already know how vital suspension tuning is, especially for drivers who had dedicated C6 Corvettes made for the track and the streets. Manipulating a suspension setup is exceptionally crucial if you want to condition your car for various driving styles. 

General Advantages of Coilovers

We’ve already stressed enough in this article how banger of a performance mod coilovers are, even for a Chevrolet Corvette C6. However, we still haven’t given you the general advantages you can get once you’ve decided to get rid of those leaf springs in place of new aftermarket coilovers.

Here are the advantages you can expect to get once you’ve installed coilovers on your car.

  1. Improved handling. Coilovers can help you plant your car to the ground more firmly than leaf springs. This is because the center of gravity of a lowered car is much closer to the ground. The lower the car’s center of gravity is, the stable it gets while driving. Be sure not to drop it too low because it will have adverse effects on how your car handles.
  1. Lower ground clearance. One of the aces of coilovers is its ride height adjustability. Most coilovers in the market offer a decent range of ride height adjustment, from stock height to a certain level, say -1.0” or more. There’s nothing sexier than a sports car that has a lowered stance.
  1. Adjustability. As stressed out multiple times earlier, coilovers offer car enthusiasts tuning freedom. With this mod, you can tweak your suspension’s settings as much as you’d like, as long as it’s within the range of what the coilovers are capable of.
  1. Prestige. The fact that you’ve gotten rid of the stock leaf springs and replaced them with coilovers is more than enough to attract attention from your peers. This signifies that you’re serious with your passion for racing, and you’ve chosen the C6 Corvette as your champion.

Why Should You Concern Yourself With Coilovers?

Coilovers offer the adjustability that leaf springs can’t. Most coilovers offer dampening adjustability, which is an essential factor when you want a track-dedicated C6 Corvette. You’d like to make your car handle better through twists and turns, an ever-present feature in the topography of most race tracks (and even the streets).

There’s a whole engineering suspension science concerning the differences between leaf springs and coilovers. Such discussion is concerningly tricky to understand for a typical car enthusiast.

Regular leaf springs like the ones present on a C6 Corvette are half as stiff as the coil springs to keep it short and straightforward. The leaf springs used by the Corvette can’t provide the necessary spring rate for a driving style intended for peak performance in competitive racing.

Coilovers are the winning components you’d need if you want to dedicate your C6 Corvette to a track/street behemoth. C6 Corvette owners can provide damping and ride height adjustability, something leaf springs can’t do.

However, keep in mind that even though coilovers can provide ‘Vette owners tuning freedom, not all coilovers offer both dampening and height adjustability. 

Some coilovers are single adjustable, while others are double adjustable. Single adjustable coilovers mean that you can change both the rebound and compression configuration of the coilover simultaneously.

On the other hand, double adjustable coilovers offer independent adjustability for both the compression and the rebound.

A Quick Note Before You Install A Coilover Conversion

After reading through this article, you now have a good grasp of what coilovers are capable of, particularly on a C6 Corvette. Now, let’s talk about YOU deciding on purchasing a coilover kit of your choosing.

Do you need a coilover kit for your Chevrolet Corvette C6?

The Chevrolet Corvette showed the world that leaf springs can still give a performance car excellent handling. A lot of Corvette owners are mesmerized by how well these cars run on the streets.

For them, the transverse leaf springs present on their vehicles are enough. No more coilover conversions, no more head-churning labor costs – just leaf springs. Plain and simple.

Spirited drivers, on the other hand, prefer something that will cater to their specific driving style. That’s why coilovers are good for them. It allows them to tune in their suspensions for the particular setting they want, and it gives them more road feel whenever they drive their cars aggressively.

Sure, coilovers are a tad bit expensive, but for car enthusiasts dedicated to having the best time while racing, coilovers are just a means to an end.

What’s the point here? Please think twice before installing coilovers on your Chevrolet Corvette C6 because they’re some serious modifications. It will drastically change the way you drive your car, and turning your back on your objective of improving the car’s handling will cost you a lot, both time and effort.

If you’re eager to make your Chevrolet Corvette C6 a dedicated track car (or a more tenacious street racer), then you should go for coilovers. However, if you’re satisfied with how the leaf springs perform and you’re not into competitive racing, then you might want to stick with stock leaf springs for now.
