The Reason Why Your to Upgrade Your Subaru WRX’s Suspension System 

The Subaru WRX came from a line of hyper performing rally cars that dominated the racing scene for far too long. At default, it has a high-performance suspension system that can do you wonders at its best. 

But what if you can upgrade them? To ask a better question, why should you even upgrade them in the first place?

  • Lowered Center of Gravity

    Once your Subaru WRX is installed with the right coilovers, the center of gravity will be lowered enough to allow you to corner and maneuver better. It stiffens up your chassis too. Nothing looks cooler than a lowered Subaru WRX, right?
  • Adjustability

    Subaru WRX drivers, just like any driver who loves their car so much, would love to control every aspect of the car. This is to ensure that everything functions perfectly. Coilovers offer the same relief, in the form of adjustability.Coilovers oftentimes comes with adjustable systems. Adjustable ride height allows you to control the Subaru WRX’s ride height to whatever you see fit. You want it lowered just a little bit or do you want it lowered to the extreme? Your choice!
  • A High Level of PrestigeWhether we like it or not, most neck-turning cars are those with lowered set-ups. When you tell your friends that you’ve got a coilover installed in your Subaru WRX, chances are you’ll get some additional points. Why? Because suspension system upgrades are cool!

    Aside from that, coilovers are well known to be a performance mod. A Subaru WRX equipped with aftermarket performance mods is more likely to perform better than a Subie without any performance mod installed.

Four Key Things to Look Out For When Buying A Coilover

  1. Spring RatesThe right spring rate will determine the capability of the vehicle to handle bounces and bumps.
  2. Adjustability of the Springs and ValvingGaining control over your car’s springs and valving will give you an edge. A fine-tuned Subaru WRX will give you better handling capabilities and control over your car’s ride height.
  3. Top MountAftermarket coilovers offer stiffer rubbers on the top mount that makes the coilover last longer.
  4. Tube DesignFor the Subaru WRX, the better choice to make is to purchase monotube shocks instead of twin-tube shocks. This is because monotube shocks are designed to perform better on street and track compared to the twin-tube shocks.

Buying the right coilover kit for your Subaru WRX will determine the difference between a hassle-free ride and a stressful ride. But in the end, a Subaru WRX with an upgraded suspension system is far better than a Subie without one.
