A set of lowering springs are among the best lowering mods you can get for your vehicle. It’s cheap, it’s easy to find, and installing them wouldn’t take so much of your time (as long as you know how to!). Lowering springs are for car enthusiasts who primarily want to see their car’s ride height reduced and don’t care that much about improving it’s handling. To put it simply, a set of lowering springs is good enough to improve a car’s stance.

Lowering Springs vs. Coilovers: What’s The Difference?

Being confused with choosing lowering springs or coilovers is normal, especially for those who want to reduce their cars while trying to improve their handling at the same time. Both lowering springs and coilovers have their own advantages and disadvantages, so let’s explore these two mods to help you determine what’s the best mod you should get for your Toyota GR Supra.

What Are Lowering Springs?

When a car aficionado wants to lower their car, and they couldn’t care less about changing its ride quality, often they choose lowering springs. These mods are great because they’re pretty straightforward. As the name suggests, these springs “lower” a vehicle. It reduces the ride height of a car at a specific limit, usually up to 1.5″ or even more. If you’re lucky, then there will be a slight change in the car’s ride quality too.

Aside from the height reduction, lowering mods are pretty affordable too. It’s easy to get, and they aren’t as large and bulky as coilovers or even air suspensions. This mod offers other benefits, like better aerodynamic characteristics, improved traction, and reduced rollover risks. Overall, lowering springs are a go-to mod for car enthusiasts looking forward to reducing their vehicle’s ride height without breaking the bank.

Advantages of Lowering Springs

  1. Improved aerodynamic characteristics for your vehicle

Have you ever wondered why sports cars have low ground clearance? It’s because when the vehicle is lowered, there’s less air hitting the wheels, thus reducing air drag. A car with a low air drag often translates to a vehicle with an improved fuel economy, but do take note that lowering a vehicle too much will ironically increase the air drag.

  1. Improved traction and handling

Installing a good set of lowering springs in your car will make its center of gravity lower, allowing the vehicle to increase its tire grip and improve its handling. Another effect of a lowered center of gravity is stability. Because of the stiffer springs, the car’s weight transfer is more effective, especially if you hit the gas or brake hard. 

  1. Reduced Rollover Risks

Here’s a rule of thumb regarding cars: the higher the vehicle sits, the more prone it is to rollovers. That’s because when an object’s center of gravity is high, it’s easier to tip over. That’s also the reason why SUVs and pickup trucks are more prone to rollovers than other types of cars like sedans and other similar passenger vehicles. So when you put lowering springs in your vehicle, you reduce its rollover risks.

  1. Greater driving comfort

A lowered suspension does help a driver be more in tune with how their cars act whenever driven by varying road conditions. When a car’s lowering springs are stiff enough, it improves the vehicle response, which helps the driver know-how driving on specific pavements feels like: as if the driver and the vehicle are one. This feeling gives some drivers comfort because they now know how to respond accordingly to different road conditions.

Disadvantages of Lowering Springs

  1. Increased risks of bottoming out

We all know how it feels whenever a lowered car goes through a speed bump and scratches its underside. You could even ruin the front of your vehicle wherever you go through the lip of your parking garage! Contacts like these are dangerous to the parts on the belly of your car, and when the worst-case scenario comes, it can ruin the region underneath your vehicle, like the exhaust system and oil pan. 

  1. Can cause uneven tire wear

Improper installation of lowering springs can cause your car to have an alignment problem, resulting in uneven or extreme tire wear patterns. Whenever you reduce your car’s height, you’re also changing its wheel-to-tire fitment. So whenever you introduce some lowering mods to your vehicle, make sure to get the help of an expert and realign your suspension.

  1. May cause some conflict with other car parts

Another danger of getting lowering springs is that the suspensions may get caught up with the other systems present in your vehicle, like the anti-lock brake apparatus, tire sidewalls, sway bars, etc. And as mentioned earlier, an incorrectly set up suspension may cause more damage to your tires and can put you into some grave situation.

  1. Difficulty in lifting and towing the car

A lowered car means that it’s more challenging to tow or lift. That may be a huge problem whenever you have to do your routine maintenance because doing a simple job like using manual jacks to raise your vehicle can be more problematic. Before you lower your car, consider first if you can cope with this kind of difficulty before allowing your car to kiss the ground.

What Are Coilovers?

Lowering springs are great, but it doesn’t offer many benefits to improve a vehicle’s handling. Because of this problem, many car enthusiasts opt for coilovers instead. Coilovers, coined from the phrase “coil over struts,” is basically a combination of spring coils and shock absorbers. It combines what lowering springs can and cannot do: lower a car’s ride height and offers adjustability.

Most coilovers offer ride height and damper settings adjustability. It’s often the choice for car enthusiasts who want to tune their suspensions to adjust how their suspensions respond to different driving scenarios like aggressive street driving, track racing, off-road, and many more. Coilovers are great because you can change how soft or stiff you want your suspensions to be according to the road conditions you’re going to face.

Advantages of Coilovers

  1. Improved handling

One guaranteed thing that coilovers can do is that lowering springs couldn’t significantly change a vehicle’s handling. Installing coilovers in your car is a sure way to get a sportier car that’s more capable of aggressive driving, on streets or even on tracks. Coilovers are often the choice of car enthusiasts who want to feel like a professional race car driver, or like the protagonists in the The Fast and The Furious movies. 

  1. Decreased ground clearance

Just like lowering springs, coilovers can reduce a car’s ground clearance too. Popular coilovers even offer full-length ride height adjustability for people who change their minds way too often. This decrease in ride height introduces some benefits, like better mileage because of better aerodynamics, a lowered center of gravity, etc. And also, it gives your Toyota GR Supra A90 a pretty sick aesthetic appeal too.

  1. Adjustability

Freedom is such a blissful thing. This very freedom is what most coilover offers those who want more control over their car’s ride height and damper settings. Most coilovers these days have damper setting adjustments from 15 to 32 levels. Some coilovers even offer full-length adjustable coilovers so you can lower your vehicle without affecting the spring preload settings. Coilovers are one of the ideal mods a hardcore car guy should get simply because it significantly affect a car’s ride quality.

  1. Prestige

Letting your gear head friends see your newly lowered car is fantastic. However, telling them that you’ve got high-quality coilovers installed and seeing their reaction is even better. Coilovers are among the most esteemed mods you can get for a car, and it often signifies that you’re a real car guy and not just somebody that’s pretending to be one. Just wait and see what your friends’ reaction will be once they discovered that you’ve got new coilovers!

Disadvantages of Coilovers

  1. Stiffer ride

A stiffer ride is arguably one of the most common complaints given by coilover users, even the ones who are using coilovers for 2020 Supra. Some drivers claim that coilovers make their riding experience uncomfortable because it’s too stiff. Coilovers are meant to be stiff so the vehicle can handle turns and corners effectively, but luckily for drivers like you, some coilovers are made to maintain an OEM ride quality.

  1. Possibility of failure

Cheap coilovers can be more of a liability instead of an investment due to some concerning reasons. A low-quality coilover may give up on you sooner than you expect and may result in failure whenever you drive into specific types of roads. Before you purchase a coilover kit, make sure you do your homework first and read up info about your particular choice of coilovers. Some great sources of information would be forums and customer reviews.

  1. May eat up more space.

Some coilovers tend to eat up more space than they’re intended to. Whenever this happens, the coilovers may get tangled up and make contact with parts like sway bars, wires, anti-lock brakes, and even damage the tires, as mentioned above. This is a serious issue, and overlooking this may put your car into some severe damage.

Lowering Springs Vs. Coilovers: Which Should I Choose?

For every problem, there are always multiple available solutions. This same principle applies to your suspension lowering needs too. The answer to what lowering mod is the best for a Toyota GR Supra is not a one-size-fits-all solution. Everything will eventually go down to three main criteria: how you will use your car, how many dollar bills you are willing to spend, and your expectations.

Suppose you’re budget-oriented, and you’re just looking forward to having a relaxed, lowered stance that’ll be the center of attention (you have a Toyota GR Supra: you’re already the center of attention!). You don’t care much about handling improvements. In that case, you should get your hands on some good quality lowering springs.

However, if you have attention to detail and want your car to be more responsive, have improved handling, and dominate both the track and streets with aggressive driving, then coilovers are for you.
