For typical cars, engineers often have to consider various performance-related issues when designing them. This includes the likes of bumper elevation and general ground clearance. Cars need space, whether it is allowing for speed bumps, snow chains or just to handle slopes and elevation.
As such, cars are set up with suspension systems that is suitable for standard accelerating, braking and cornering conditions. Of course, there are drivers who are not happy about this and wish to lower the suspension, both for sports needs and for aesthetic preferences.
Lowering the suspension
Fortunately, the standard settings on a typical car can be readily adapted to meet these drivers’ needs. If you want your vehicle to look, feel and drive like a sports car, or if you want to power through the streets and handle corners with confidence, sporting springs can help you achieve this.
Many drivers prefer lower suspension on their car for aesthetic purposes.
Likewise, a lower suspension will make your car look more aggressive, while enabling you to steer more confidently. This, naturally, appeals to many drivers, many of whom have decided to replace their original car tyres and rims with sportier alternatives, in addition to lowering their suspension.
Why sports springs?
If you decide to lower your suspension, do not do it yourself. Modifying the default settings yourself will always end up unsatisfactory. Cutting the factory springs, for instance, can prove very detrimental to your car’s stiffness, increasing the internal tension and making normal suspension functionality impossible.
This is why you are better off investing in properly manufactured sporting springs. Not only will these fit the car, they will also significantly improve its appearance and performance. Sports springs will help to lower the vehicle, giving it a more aggressive appearance, while also decreasing the clearance in the wheel housing. This refers to the space between the car tyre and the rim of the wheel housing. On a car with lowered suspension, it often looks like the tyre is ‘filling’ this space.
You can lower suspension with the use of sports springs.
As far as performance goes, sporting springs provide two key improvements. First of all these springs lower the driving height and provide stiffer suspension. This lowers the centre of gravity, while providing sufficient carrying capacity, improving the overall stability.
Secondly, lowering your car in this manner improves reactions through decreased body movements. In turn, this allows the tyres to operate more efficiently during extreme driving, when they are often on the verge of utilising their full strength.
If you decide to lower your suspension, you should also consider using a complete coil-over system, which includes a spring, shock absorber and an adjustable spring perch. Their settings closely resemble a typical sports performance package, as they allow you to tune your vehicle more finely, thanks to an adjustable height.
How low should You go?
When it comes to vehicle customisation, this is one of the most commonly asked questions. As a general rule, most passenger vehicles can be lowered by about 40 mm without any problems. If you decide to go further than this, you should note that there is a greater chance of the suspension having a negative influence on your driving quality and tyre wear rate, alongside the increased hazard of scratching your car’s underside on the ground.
While a lower suspension can be aesthetically pleasing, some ground clearance is still required.
Remember to adjust the wheels!
Any time you lower your suspension, you should also correct your wheels’ adjustment. This, again, is something you should not do yourself, as it is hard to adjust the wheels after the suspension has been significantly lowered without the use of specialised suspension adjustment tools.
You should also bear in mind that a shortened suspension carries a greater risk of scratching your car’s underside. In the car’s original equipment, this problem is solved with bump stops and these should only be removed or modified if it is recommended by the manufacturer of the replacement springs.
