The Subaru BRZ Coilover basics

Coilovers make it possible for you to set up your Subaru BRZ damping and height to lower the center of gravity for improved stability. They also stiffen the chassis for better turning and control. With coilovers, your Subaru will look sportier, which is always better when it comes to a Subaru. Coilovers also allow you to transform your car by improving the performance.

With so many Coilover brands in the market, picking the right one can be a daunting task. Here is what you need to look for in the best coilovers for BRZ Subaru.

Spring rates

Springs are an important part of any suspension setup. They are responsible for controlling the car’s bounce ability, absorb bumps, and create a low body roll when loaded. A higher spring rate will require more force for spring compression, which will reduce the suspension travel.

The body of a vehicle moves whenever the driver accelerates, turns, or brakes. When you reduce the body movement, the handling becomes more predictable and spreads the load across all wheels effectively, boosting the grip.

Many aftermarket coilovers are made with stiffer springs as compared to OEM suspension. This improves handling, giving the driver a better feel of the road and car, especially for spirited driving.

Valving and spring adjustability

The most common reason people purchase coilovers for Subaru BRZs is to lower the car. This reduces the center of gravity, which in turn reduces excessive body roll and improves performance. Having ride height adjustability, spring preload, and damping are important features for any good quality Coilover.

Adjusting the Coilover makes it easier for you to fine-tune the vehicle handling and gives it an ideal ride height for any application. You also need to be able to replace the coilover springs with stiffer ones, especially for track cars that require higher spring rates compared to streetcars. Stiffer springs deliver a better grip, reduced body roll, and improved handling.

When switching to softer or stiffer springs, you need to match the spring rate with damping to avoid having a bouncy ride, which can affect the car’s handling.

The top mount

A top mount is located at the top of a Coilover to hold the parts together and joins the top of the Coilover to the car. Between the mount and the strut assembly, you will find 2 different bushings; the pillow ball type and rubber type.

OE manufacturers prefer rubber bushing to pillowball bushing because they deflect more, which a common cause of suspension precision failure. The rubber used on OEM struts is soft, which allows energy deflection. Using stiffer rubber mounts can improve longevity and prevent energy deflection.

On the other hand, a pillowball bushing is made of a spherical metallic joint that remains in place. This lack of deflection from cornering forces gives a better feel from steering and suspension.

Monotube designing

In every Coilover, dampers can be designed as a monotube or a twin-tube. The latter is made with an inner or outer tube where the inner one holds the piston shaft, oil, and valve while the outer tube holds the nitrogen gas and the damper oil.

During suspension compression, the piston in a twin-tube forces oil from the inner tube to the valve and then the outer tube. When the piston retracts, the oil in the outer tube is sucked back to the inner tube. This type of dumper system is common in OEM suspensions as it allows more suspension stroke, which improves the quality of the ride.

For monotube dampers, the gas and shock are held in one tube with a floating piston separating the gas from the liquid. This design pushes the damper piston through the oil and the oil through the chambers in the valves. The Monotube dampers design support gas compression, where the compression is slow on small bumps and fast over large bumps.

A benefit of monotube dampers is the ability to use them either way up, which is not possible for twin-tube dampers. In addition, monotube dampers have a higher fluid capacity than twin-tube dampers. They also deliver better heat dissipation, which improves the damper effectiveness.

For high-end Subaru BRZ performance on track or street, the monotube design comes highly recommended and is a superior upgrade from twin-tube damper designs.

Sway bars for the Subaru BRZ

By default, most factory cars come fitted with an understeer bias to make them easier to drive within the limit and safer. Sway bars are used to bring the car to a neutral state. Upgrading your BRZ rear bar with a 25mm sway bar can correct all understeering issues with the car. The type of bar used and the size can make a difference in car handling.

When lowering a vehicle, the suspension geometry is changed, which can incorrectly preload the sway bars, causing unpredicted handling issues or even damage. To prevent this, you can use adjustable end links for the correct preloading of a sway bar.

The benefits of coilovers

The prestige

Coilover suspensions are high-end adjustments for any vehicle. Telling your auto-biffed acquaintances that you installed coilovers will definitely garner you some points. Ensure you go for aftermarket coilovers, as these are the better choice for specialized setups.

Good vehicle handling

Most car enthusiasts prefer to improve the handling using coilovers compared to stock suspension systems they come with from the manufacturer. Coilovers setup a customized suspension that enables the system to navigate better in cornering and other kinds of driving.

Ability to upgrade and adjust

BRZ drivers love that Coilover suspensions can be adjusted. This is perfect for anyone interested in lowering the car for on-road use. These custom suspensions can also support a high setting for off-road use. The ability to set the suspension in any way you prefer is one of the main benefits of Coilover systems.

Final thought

This guide covers the best coilovers for Subaru BRZ. Rated from the most affordable to the most expensive of the four, any of these options comes highly recommended for your Subaru BRZ. If you are looking for a way to prevent your chassis from bottoming out, reduce body roll, and protect your wheels, investing in coilovers is a consideration worth making.
