Function of chassis reinforcements
The chassis of your vehicle
The chassis of an origin vehicle is basically designed to protect occupants, to ensure their safety and comfort.A chassis is never rigid as it is a rigid steel bar, it has some flexibility, even if it seems to us at a simple sight that it is not so.
If you catch a steel wire like the ones that are used in construction from the two extremes, you will see that it practically does not deform, but if you catch from the two extremes a long steel bar, you will see that it is curved by the center and by transporting it moves with oscillations and more pronounced as more bats or jumping pills.
For something similar happens with the chassis of a vehicle, it is not rigid so that it does not absorb the irregularities of the ground and passes them to passengers.
The harder the suspensions we mount, the less they will amortise the strikes and the more they will absorb the chassis, weakening it more and more until it breaks and / or breaks, losing safety and stability.
Climate agents also attack the chassis (extreme temperatures, rain, snow, salitre, stone, etc.) especially in those unions and weldings that are susceptible to corrosion.
What are the reinforcement bars?
Despite the fact that there are many users who mount torrents and other chassis reinforcements as if aesthetic elements were treated to look more like a racing car, the truth is that we are adding more rigidity to the chassis and therefore we will change your behavior.
The more reinforcements we add, the more the chassis behavior will vary.It is very possible that by adding a single bar we will not notice an obvious change at first sight of the chassis behavior, but if we add an antivulc bar, reinforcement torrets bar, subchassis reinforcements, side reinforcements and stabilizers, then we will be faced with a great change in the chassis behavior.
By mounting these elements we succeed in strengthening the chassis, giving it more consistency, more structural rigidity, greater duration, greater stability and greater accuracy in the dynamic response of the car.
It is what is actually always sought in the racing cars, eliminating the tortion and flexibility of the current chassis to get more aplomo, greater accuracy in the chassis behavior and a much more instantaneous response of it to be able to have a sensitivity of a pilot and to play with the weight of the same in the circumstances we want (subviration, overviration, neutral behavior...)
Types of reinforcements for chassis
There are several types of reinforcements but are basically classified in 5 different classes:
- Stabilizing bars for front and rear axis
- Torrents for front and rear axis
- Strengths of symmetrical lateral subchassis (usually 1 pair of 2 points)
- Strengths of parallelogram subchassis (usually 1 Strength of 4 points)
- Side Fenders (usually 1 pair of 3 points)
It is recommended to always mount by couples in front/back axis, the strengths that are symmetrical (right/left) by default come served always in couples.

When is it recommended to mount chassis reinforcements?
The assembly of these elements is always closely related and recommended in engine enhancement projects, the more engine power, the more it is recommended to strengthen the chassis to endure the increase of torsions by the engine power and by the inertia forces, side G forces...
In general, it is recommended to mount strengths;
- For cars with circuit tandas
- Specially recommended if high adherence tires are mounted
- Installing hard and sports suspension
- Swaps with high power engines
It is advised to mount chassis reinforcements with the use of harder amortisers, harder mole, harder joints, spherical labels, etc
Any increase in hardness and/or reduction or elimination of an elastic element of the suspension, implies that all irregularities of the ground will be absorbed directly in greater proportion by the chassis.
That is, it will suffer more and will tend to weaken by the unions and the bonds coming to break down or broken most of the times by the unions, causing an unprecedented, erratic and insecure chassis behavior.
These defects usually pass unnoticed to the driver because they are not easily appreciable at simple sight, only appreciated when it’s already late and it’s broken somewhere.
A well reinforced and balanced chassis with the other peripheral is a more stable and managed chassis in situations of imminent collision, we can govern it much better than if we do not carry any reinforcement.
In case of accident, we are more likely to protect the occupants of the vehicle.Note that on the market there are low-cost medium-quality boost bars by ebay and similar platforms.All bars that are made artisanally or with scarce resources can result dangerous in collisions.
These elements are designed and manufactured to deform in a certain way by absorbing the energy of an impact, otherwise, the bars could be broken by half or by the weakest point like a welding and damaging the occupants with living arists.
