Check This: The Best Coilovers – Facts You Need To Know

What to Consider When Choosing Miata Coilovers 

Miata coilovers suspension kits have threaded body shocks and springs to provide you accurate and independent control over the height of every corner with your Mazda Miata.

Keep in mind that the more established coilovers are well-researched, engineered, and sometimes more expensive and are known to work best with your specific vehicle.

Miata Coilovers For High Performance Vehicles

For those who are developing a high-performance vehicle, a lowered suspension is a must-have. Most of the full coilover kits are expensive, but it does not mean that you will have to sacrifice performance with cut springs.

The Best Miata coilover sleeves provide several benefits at a reasonable price that you can also get from full coilover.

Miata Coilovers Features To Consider

The majority of the coilovers are adjustable in height and damping. But there are some that also feature threaded shock bodies that let you adjust the ride height separately from the coil spring adjustment. It also enables you to dial your spring preload for the best suspension tuning.

Can I Use Different Spring Rates?

You can swap your Mazda Miata coilover springs with other springs of different rates to adjust your ride stiffness and quality. The coilovers with adjustable damping may have up to 32 levels which are also referred to as clicks, although some riders will skip a click since the difference is very small.

The Importance Of Suspension Tuning

Suspension tuning is an important element in maximizing your Mazda Miata’s performance. However, not all driving surfaces or driving areas require the same suspension set up. Maybe the biggest advantage of Mazda Miata coilover sleeves is the fact they are adjustable.

How Can You Tell If Your Suspension Is Right

It has a threaded spring perch design: with just a simple twist of a wrench, you will be able to jack up or lower the suspension based on whether you are tackling pot-hole riddled streets or are about to hit a smooth race track. Coilover sleeves also use the normal size coilover springs so you can change spring rates easily and there are lots of springs to choose from.

Quality of Material

The durability of your Miata coilovers plays an important role in several aspects. First and foremost, all coilovers wear over time – the quality of material used in the construction process determines the overall lifespan of a sleeve and ultimately the moment when the coilover will need to be replaced, as well as the frequency of repairs. 

Some of the most popular Miata coilovers are made of high-carbon steel and steel while top-tier boutique models also feature reinforcements in terms of chrome finish (for enhanced sturdiness) or silicone (for increased overall flexibility).

Casual drivers who have no interest in racing and high-performance ventures should not completely overlook this element of a Miata coilover; even though your driving will not ’wear off’ the sleeve as much, potholes and cracked roads may end up ruining your coilover almost as fast as top-gear drifting.

Hobbyist racers and people who generally have a need for speed may want to invest in more robust Mazda Miata sleeves. However, searching for the right compromise between price, adjustability, and flexibility should take priority in this particular scenario.

Finally, professional racers who are flooring the pedal to the metal shouldn’t settle for anything less than superior durable coilovers. Needless to say, a racing Mazda Miata’s coilover wears at a rapid pace, much faster than the sleeves built into Miatas of casual drivers, so durability is mandatory.

Overall, other aspects of Miata’s coilover sleeves are also impactful factors, but sturdiness is always worth investing in. This way you will be able to gap a good portion of repair and replacement expenses while benefiting from increased long-term reliability.

Adjustability

Most coilovers are adjustable to some extent. However, Mazda Miata is a strong high-performance vehicle that requires a versatile, well-rounded coilover that can provide you with means to reduce the car’s body roll, improve its handling, and provide a balanced weight transfer during sharp turns.

Now, depending on how you intend you use your Mazda Miata, there are several things to consider when looking at the adjustability of your coilover.

First and foremost, the main purpose of a Miata coilover is to lower the center of gravity of the vehicle by lowering its ride height. Top-quality models can lower the ride up to four inches while average models normally go up to two. This provides a more balanced distribution of weight, which in turn tremendously helps control the vehicle while drifting and steering.

The versatility of the adjustability aspect of Miata coilovers also heavily influences the overall handling of your vehicle. Smooth acceleration, stable cornering, and controlled braking are just some of the factors that are directly affected by how adjustable your Miata coilover sleeve is.

The weight and height adjustment aspects are some of the most crucial ones. Budget Miata coilovers affect the suspension travel and spring compression due to the lack of the control arm mount while boutique models (which are supplied with this feature) do not change spring compression and travel.

Furthermore, highly adjustable Miata coilovers allow you to adjust the reactivity of the bump stop. This allows you to directly influence the speed of compression, which further affects the responsiveness of your Miata’s suspension.

Casual Miata drivers may find coilover sleeves as best as they offer decent adjustability while being the least demanding in terms of installation. Higher adjustability becomes available at higher price points and is mandatory for professional racers while enthusiasts are recommended to go with shock-adjustable coilovers.

Coilover Types

Mazda Miata coilovers can be categorized into several different types – coilover sleeves, non-shock adjustable coilovers, shock adjustable coilovers, and shock adjustable coilovers with a Camber kit. Understanding the benefits and drawbacks of each type can help you determine which Miata coilover can best cater to your needs.

Coilover Sleeves

Sleeves do not feature struts and adjustable shock mounts and are meant to be installed on pre-built shocks via top mounts. Coilover Miata sleeves are regarded as low-cost upgrades and they are not capable of dramatically enhancing the vehicle’s performance. Fortunately, this is their only drawback.

Coilover sleeves for Mazda Miata are generally inexpensive and the easiest to install. They’re an excellent option for beginner racers and people who are on a tight budget.

Non-shock Adjustable Coilovers

Next up we have non-shock adjustable coilovers. Despite the name, this coilover type is actually fairly adjustable. In comparison to coilover sleeves, non-shock adjustable coilover represents a full-bodied suspension upgrade that is equipped with proprietary shocks (which is not adjustable, hence the name).

The drawback of this Miata coilover type lies in its poor flexibility – you will not be able to adjust the rebound, stiffness, or compression of its shock absorbers. On the upside, the benefits are numerous, including simple installation and maintenance, relative inexpensiveness in comparison to their shock-adjustable counterparts, and simplified ride height adjustments.

Non-shock adjustable coilovers are absolutely perfect for hobbyists and enthusiasts who want a full-bodied suspension upgrade with minimal tweaking.

Shock-adjustable Coilovers

The shock-adjustable coilover type is the second most versatile Miata coilover type. Generally speaking, both shock-adjustable and non-shock adjustable types share very similar (and often identical) features while the former is superior in adjustability.

Where the non-shock adjustable coilovers are ’stiff’ in terms of rebound & compression, the shock-adjustable coilovers provide access to this form of tinkering.

Even though this type of Miata coilover is a bit more expensive than the previous two, it offers a substantial boost to the comfortability of driving and handling. This makes them an excellent all-around option for any scenario, be it day-to-day cruising or racing.

Shock-adjustable Coilovers with Camber Kit

A Camber kit is a feature that is crucial to the final stages of optimizing your Miata coilover. Car workshops and repair centers are supplied with these kits, so even if you don’t have one you can always drive your Miata over for fine-tuning.

However, adjusting the camber level of your Mazda is not a one-time thing, and you may end up racking tweaking expenses that surpass the cost of the Camber Kit.

Miata coilovers that come supplied with this kit offer superior adjustability; you’ll be able to fully optimize both your suspension and tires, prolong their lifetime, and substantially improve your Miata’s handling.

Price

Differences between entry-level, mid-range, and boutique coilovers are expressed through the quality and quantity of features. When it’s worth investing in quality Miata coilovers and in which cases budget coilovers could make a difference

Miata coilovers can also be categorized into different price point categories. Budget-friendly models are usually supplied with the most basic features and offer little in terms of adjustability and versatility while top-tier boutique coilovers are sturdier, more reliable and substantially better-rounded.

Amateur racers and casual drivers will see a difference when upgrading to Miata coilovers in terms of day-to-day driving comfort, better steering and enhanced overall handling. However, entry-level coilover sleeves pale in comparison to mid-range and boutique models.

Budget Mazda Miata coilovers are worth the buck if you’re using factory shock absorbers and don’t particularly like how they respond to the road. Even though the changes in your vehicle’s stability and weight transfer may ’feel’ the same at first, you will start noticing changes after a couple of rides.

Pricier coilovers come supplied with fully adjustable features; they can last several times longer, and they are perfectly suited for racers in-the-making as well as for professional drivers.

FAQ

What kind of Coilovers Can I Install In My Miata?

Most full-bodied coilovers are compatible with Mazda Miata; this includes a broad spectrum of shock-adjustable coilovers and non-shock adjustable coilovers while the selection of coilover sleeves is sparse in comparison to the former.

How to setup my Miata Coilover?

The first step entails measuring your Miata’s ride height. Park the vehicle on level ground before taking the measurements from the car’s center-of-the-wheel down to the end of the fender. After that, you should mark the bolts (preferably with penetrating oil) and remove the wheels. For this step you’ll need a jack stand; otherwise, you’ll need to drive your Miata to a car workshop.

Next, you’ll want to remove the struts and set the ride height. If you are using shock-adjustable coilovers, this can be done by altering the pre-load of the spring. Now that the area where your coilover should be placed is exposed, all that is left is to use compatible tools (wrenches and hardware) to install it.

Are budget Miata coilovers valuable for the money?

Performance-wise, the differences between budget and boutique Miata coilovers are insurmountable. However, even the cheapest sleeves are sturdy and reliable, and you will experience a difference in terms of handling your Miata.

Should I tweak my Miata’s ride height with a Miata coilover? What are the risks/benefits?

The first thing you need to know about changing your Miata’s ride height is that you’ll need to re-align pretty much everything every time you do it. This can be financially challenging if you don’t own a well-equipped garage, but luckily this is the only drawback.

The benefits of altering your ride height in your Miata are numerous; you can tweak the center point of gravity and substantially improve weight transfer, which will in turn help you tackle sharper turns. Racers typically reduce the ride height for improved aerodynamics while casual drivers increase it to make the vehicle better suited for day-to-day driving and commuting.
