Along with the advantages, undertaking this kind of suspension project has a variety of drawbacks, such as:
- Variable Tire Wear Your tires may occasionally wear unevenly or even develop excessive wear patterns if your suspension is lowered. When you change any of the suspension system’s factory-installed components, this may occur.
- Increased Bottoming OutDrivers with lowered suspensions frequently complain about this issue. Contact with the road when you decrease suspension frequently seriously harms other auto systems. The oil pan and exhaust system of your car are particularly prone to damage.
- Conflict with Other Car Systems Could Occur
- The greatest detrimental effect of lowered suspension is when components of the suspension system interact with other automotive components, including sway bars, anti-lock brakes, and even tire side walls. Installation of lowered vehicle and truck suspensions must be done correctly to avoid system conflicts.
- Lift and Towing Issues
- Once the suspension of your automobile, SUV, or truck has been lowered, employing a manual jack becomes an uncomfortable and challenging chore. Additionally, chain towing might cause issues.

Due to aesthetic considerations, lowering suspension services have become increasingly popular. Many automobile owners claim to have also observed additional advantages, such as better gas mileage or a reduced chance of rollover when cornering. Although lowering your car isn’t generally a bad thing, there are a few factors to take into account, such as a less comfortable ride, rough roads, or uneven tire wear.
Although lowering your car’s suspension is allowed, there are several conditions that must be followed, such as making sure that neither the front nor the rear suspension travel is lowered by more than one third from what the vehicle’s manufacturer has stated. Your vehicle must maintain a 100 mm ground clearance on all parts.
There are two ways to lower a suspension: by using coilovers or lowering springs. Lowering springs are more affordable and almost never need automotive changes. Coilovers offer more adjustability but are typically more pricey.
The cost of the procedure varies significantly based on the car’s model as well as the kind of lowering kit you select. The cost is also influenced by the system’s complexity.
Although many people ask for lowering suspension services for cosmetic reasons, the procedure has a number of advantages. You’ll benefit from greater handling, lower rollover danger, and reduced roll when cornering, while your car will experience increased aerodynamics and traction.

Can automobile springs be lowered?
Lowering is the process of lowering the vehicle’s body by installing different suspension parts, such as coilovers, lowering springs, and sports suspensions. Usually done for aesthetic purposes, but it can also enhance handling and performance.
How much would lowering my car cost?
Typically, lowering your car by up to 2 inches costs between $100 and $5,000. How and where you choose to have your automobile lowered will affect the price.
Drop spindles, which typically cost $100 at most aftermarket suppliers, are used by many people to lower their cars. However, since the drop spindles need to be removed and disassembled in order to be installed, it can be challenging to do it yourself.
A mechanic is usually needed for this task because numerous steps must be taken in a certain order to maintain the car functioning properly. In addition to drop spindles, you may also utilize springs to lower your car, and doing so is far simpler than setting up drop spindles.
High-performance coil-over kits are made by companies like Eibach and can lower your car in just one hour. Anyone with a pair of tools can install the car lowering kits, which cost roughly $1,000.
You might want to think about purchasing coilovers if money is no object. The ideal option to lower your car is with a coilover because it offers a ride height setting that can be adjusted depending on the type of road or track you’re driving on. For a more comfortable ride, it combines a coil spring and a shock absorber.
Although they can cost up to $2,000, coilovers allow you greater control over how high or low your car goes.
Additionally, bear in mind that while adjusting the height of your suspension system, bigger isn’t necessarily better. The safest and most sensible option, as a rule of thumb, is to lower your car by half to one and a half inches. You can still benefit from a reduced ride height thanks to it without compromising on performance or safety.
Does lowering a car make it handle better?
Better aerodynamics: When an automobile is parked closer to the ground, less air passes underneath it, which results in reduced wind resistance on the car.
Better traction and handling are typically the results of lowering the car closer to the ground, which increases the tires’ traction on the pavement and enhances handling. This isn’t necessarily the case, though, as certain cars may actually handle worse if their suspension is lowered.
Reduced risk of rollover: Any vehicle that has a high center of gravity is at risk of tipping over because of this. The chance of a rollover is decreased by lowering the suspension since it lowers the center of gravity.
Enhanced comfort: Although this benefit is somewhat arbitrary, some drivers claim that lowering the suspension makes their car more pleasant and less likely to shake.
Lowering springs: do they harm shocks?
It should go without saying that lowering your automobile will change the way it looks and handles. There are a few ways to get that great lowered stance and better handling, but one of the most popular and reasonably priced ways to do it is by employing a set of lowering springs. In addition to being designed stiffer to help further reduce undesirable body motions, lowering springs are often built shorter overall than factory springs. Despite being excellent at both of these tasks, they do have some additional problems.
People frequently state that they want to keep their factory ride while also lowering their car, thus they think using just lowering springs is the ideal solution. It should continue to ride the same as long as the factory shocks are still in place, right? This is frequently false, far from the truth. The overall ride quality of your factory shocks is set to perform best at the stock ride height. Since lowering springs are often shorter than factory springs, your shocks will ride lower during their travel than they were intended to while seated at the standard ride height.
What could go wrong?
For instance, if your lowering springs lower the car by an inch, then when you drive over a bump that causes the suspension to compress by an inch, you will be sitting at the same place in the shocks’ travel. In order to help slow down the motion of the suspension so that the ride is smoother over bumps and the vehicle is less likely to bottom out under normal circumstances, this range of travel is often firmer than the initial portion of the shocks’ movement.
- This portion of the shock’s stroke is designed to handle significant road imperfections; it is not flexible enough to smooth out lesser imperfections and rough surfaces, which contributes significantly to your car’s overall harshness.
- You will significantly restrict your shock’s compression travel, increasing the likelihood that it may bottom out, because the dampers will be sitting lower in their overall travel at riding height. Limiting compression travel is one of the worst things you can do for your ride quality since, as I’ve said before, there is no suspension worse than none as all.
- You run the risk of causing your shock to prematurely wear out and lose all of its effectiveness if you bottom it out too frequently.
- The last problem with factory shocks and lowering springs is that frequently, stock shocks are not valved to handle the increased spring rate that is typically present on lowering springs. Since the main function of your shocks is to absorb the motion of the spring, your spring rate heavily influences the appropriate valving and tuning for your shocks. You run the danger of using more spring rate than your shocks can tolerate and making your ride extremely bumpy if you increase your spring rate without tweaking your shocks.
An excellent illustration of this is operating a car with worn shocks. The action of the springs is not being efficiently reduced since the shocks are no longer working as they should, which results in a rough and bouncy ride for the car.
Sources of Poor Ride Quality
- Since the recovery stroke of the shock (imagine expansion when the wheel descends back to the pavement) isn’t muted, a harsh ride quality results from a lack of rebound damping off bumps.
- When the shock has no remaining compression or rebound damping, the ride becomes bouncy (like a boat).
Should I get lowering springs?
Sure! Just keep in mind that it is IMPERATIVE that you take into account lowering springs paired with high quality aftermarket shocks and struts meant to be utilized with lowered automobiles if maintaining ride comfort is top on your list while lowering the vehicle. Lowering springs and struts can also be replaced by a sturdy set of coilovers. For a range of automobiles, manufacturers such as Bilstein, Koni, Eibach, and even KYB provide extremely high-quality monotube shock absorbers with shorter total shock bodies to better utilize suspension travel. Numerous times, while being appropriately valved for the shorter, stiffer springs, these high-quality dampers will actually improve ride over factory units.
The Coilover Option
In a system built from the ground up to be low, a good pair of coilovers from manufacturers like KW, Bilstein, Pedders, or Tanabe also frequently offer even higher quality dampers, typically with height adjustment as well. Furthermore, compared to even a set of shocks and struts for lowering springs, the majority of coilover systems will provide considerably more useful suspension travel.
Are lower riding heights preferable?
1. I’ve never changed the ride height before. How high should I set my car’s ride height?
Using conventional springs, it is not advised to significantly lower the ride height. Keep your descent between 30 and 40 millimeters. Too much lowering could cause the wheel arch and tires to collide. The balance between the front and rear should be identical to OE, or 5 to 10mm lower in the front. For vehicles (Z32, FD3S, etc.) with low ride heights already, lowering by 10mm to 20mm will be sufficient. Find your ideal ride height for any car by making numerous modifications over time.
2. How should the spring rate and ride height be adjusted if my primary driving goal is the racetrack?
The spring rate should be raised from the default rate. The track you drive on and the tires you use will also have an impact. If you are utilizing tires with strong traction, the amount of roll will grow as you go faster due to the movement of the centrifugal force. (Please lower the lower seat because raising the spring rate will raise the ride height.) If you drive to the circuit, adhere by your local laws, but it is acceptable to lower the automobile until the tires are almost in contact. The front and rear balance should be adjusted by repeatedly driving and then adjusting in 5mm steps.
3. I lowered the bottom seat by 30mm in order to lower the ride height by 30mm. However, the real ride height decreased by 45mm. Why?
The lever ratio is the reason of this. The stroke ratio between the shock absorber and the tire is known as the lever ratio. The shock absorber to tire ratio is 1.5 to 1. The lever ratio for double wishbone types is 1.21.7. 1.0 for strut type. In the case of multi-link types, roughly 1.01.1.
4. Why is the Mark II and Supra’s front spring rate set so high, between 12k and 18k?
The lever ratio is another factor in this. Lever ratio for the front double wishbone Toyota design is roughly 1.6. The spring rate would only be in the range of 5k to 7k if it were a strut type. The ratio is roughly 1.2 for the rear. There are vehicles with high spring rates from other manufacturers, like Honda and Mazda.
5. I upped the spring rate by 4k because I recently bought the SUPER STREET DAMPER and plan to visit the circuit. Even if I reduced the seat to its lowest setting, the riding height barely changes. Why?
This is solely a result of physics. The weight of the vehicle affects the spring rate and ride height. Use 10k springs or 6k springs, for instance, if your lever ratio is 1.5, your load at spring is 300 kg, and so on. There will be a 30mm ride height difference. The difference would still be 20mm even if the lever ratio was 1.0. Of course, you must change the seat position to account for the variation (e.g. 20mm). Change to shorter springs or do rid of the helper springs if you want to lower the ride height with high spring rates. But doing so will let the springs play and limit use of the public roads. (A brief stroke is acceptable.)
6. My automobile is really low, yet the ride quality is poor. What can I do to increase the degree of comfort?
Depending on the product you use, lower ride heights allow for less secure stroke, which reduces ride comfort. You should be able to secure a sufficient stroke and enhance ride comfort if you raise the ride height by 5 to 10 mm. Thus, please try.
7. I want to cut the bump rubber in order to secure more stroke. What size should my cut be?
The bump rubber, which is affixed to the shock absorber, can be compressed to a depth of roughly 15mm. If you tamper with the bump rubber, the tire may touch the wheel arch or the drive shaft may even hit the body because this compressed height is set at the lowest height that is feasible.
Customer is solely accountable for such processes when they are undertaken. Please take all necessary precautions and implement little adjustments at a time.
8. I’ve heard that the ride comfort degrades as the ride height is lowered, but what happens if I increase the ride height?
The main spring will shrink if you elevate the lower seat lock to its highest setting, which will worsen the compliance with the road surface and ride comfort.
For all threading type ride height adjustable shock absorbers, we provide the highest adjustable seat lock height.
9. My automobile has HIGH.TECH springs, however the ride height is not as low as I had anticipated. Is the product broken?
There are instances where the bushes twist during installation, raising the ride height somewhat. (The screws on the installed section become looser when the suspension has fully rebounded. The bushes twist in the direction of the suspension’s rebound.) The lower installation points, upper/lower arm installation points, and other suspension-related locations all use rubber bushes. It could be challenging to reduce the car height if these bushes twist. Loosen the installation bolts with the car at 1G for all the suspension components (moving parts such as the arm, etc). (when the vehicle is stationary on a flat surface). Retighten all the bolts after giving the car a couple gentle rocks. The bushes should be straightened as a result, and the ride height should return to its previous setting. When driving over twisted shrubs, you could hear some odd squeaky noises. In general, the arm may be positioned at a problematic angle or at a lower riding height than usual while installing our product. There is currently a huge amount of pre-load between the outside and inside of the collar for the installed bushes. This pre-load must be eliminated. However, in motorsports, this pre-load is used by loosening the suspension above 1G, then tightening it again to tuck the car even a tiny bit lower.
10. Spring rates are written as follows when looking at springs, for example, S.TECH (2.95.5k). Does this imply that the spring rate can be selected from the available options?
This is referred to as a “variable rate,” which does not imply that you may choose the rate. The range displays the spring’s potential rate of change when driving. It has the same result as lining up all of the springs of the same rating in a row. In order to lower the ride height and stop play, variable springs are employed. The many rated springs are all contained in one variable spring. For the majority of automobiles, the spring rate range is rather wide because the helper spring would have filled more of the vehicle’s compression.
