Strut Bars are the evolutionary aftermarket addition to the regular McPherson Struts. Usually a favorite in car customization and an integral part of heavy trucks and SUVs, strut bars are now finding their place in the sun when it comes to regular small cars as well.
People consider add-on struts, especially horizontal bars, as high-performance additions to their cars. There is a general belief that McPherson struts or independent suspensions can be unstable at higher speeds. As an added feature to increase stability, the independent suspensions on each side of the vehicle are linked by a common horizontal bar called the Strut Bar.
The two suspensions on each side when connected by a common bar experience reduced flex between them and that provides much needed stability at higher speeds. This is an important feature on large heavy vehicles and high performance cars, but what makes people think that rebar can stabilize their small cars? Do smaller cars really need stability?
Well, the answer is No. Unless you’re traveling at really high speeds, which you shouldn’t be doing with normal cars anyway, you definitely don’t need extra struts to support your car’s suspension. Auto experts believe that horizontal struts have become popular as a high performance addition to cars in the name of car customization. There’s no real need for regular cars to have extra struts, but in case someone wants their vehicle to have one, there’s no serious damage either.
At most, the extra struts will make your car’s suspension stiffer, reducing ride comfort, especially on rougher terrain. Since the suspensions are linked together, there may be a slight vibration on rough roads due to reduced independent movement. Also, the added weight of the strut can decrease gas mileage to some degree. In case you are hell-bent on repairing extra struts on your vehicle, be sure to ask a skilled mechanic to do it or else there could be serious performance issues with your car’s suspension.
Most sports cars, heavy and light trucks, SUVs, 4x4s and off-road vehicles are available with reinforcement bars as standard equipment.
So what kind of vehicles need a reinforcement bar if they don’t have it as standard equipment?
If you’re optimizing your regular car to run at higher speeds and exhibit higher accelerations or powering it with turbochargers and NOS (nitrous oxide systems), then strut bar will be a useful addition to the package. If you own a larger vehicle and don’t have a strut bar as a standard accessory, you should invest in one. In that case, I would suggest used rebar, as they are almost a third of the cost of new.
To conclude, you are the best person to assess whether or not your car needs rebar. Although it is not a decision to weigh, you can weigh the pros and cons depending on the type of vehicle you own and the type of use to which you put it.
