10 Best Coilovers for WRX/STI (Daily Driving) – Expert’s Guide
If you are a proud owner of Subaru Impreza WRX and looking to improve its suspension, then you are in the right place. Suspension is a critical portion of your car, and coilovers are great tools to improve it. But they should offer certain features and cover a few factors to deliver the desired experience.
Today, we will find that out because I will be taking you on a tour of the best coilovers for WRX that you can get this year. I will try to lay it out bare in front of you to help you choose better.
How to Select the Best Coilover for WRX?
Here is the buyer’s guide for you. There are some aspects that you should keep in mind before buying coilovers for your WRX. If you are a beginner, then you should pay special attention here. So, here are six factors that I want you to go through before going into the details of this product.
Material
The material is very important when it comes to choosing the best coilovers. You will find steel alloys, aluminum, and carbon steel in the market. Steel alloy is pretty robust but heavy. On the other hand, Aluminum has two common grades for coilovers; 6061 and 6063. The latter one is superior owing to its better metallic properties.
Structure
Then comes the structure. There are two types commonly observed; monotube and twin-tube. In a monotube, there is one chamber containing oil and gas. At the same time, the twin-tube has two chambers; inner and outer. One of them contains oil while the other one contains gas. The monotube structure ensures better damping. At the same time, the twin tube has low resilience and provides a sufficient stroke.
Adjustability
The next aspect is adjustability. It can be height, tension, or damping adjustability. Usually, all the coilovers offer height adjustability. Other than that, many offer tension adjustments to offer you desired stiffness. There are some incredible coilovers that also offer damping adjustment. This feature enhances the functionality and takes the experience to a whole new level.
Compatibility
You always have to make sure about the compatibility. Look closely for the details of your car and match them to the compatibility of the product. Also, some products are widely compatible, and you can use them on many cars. So, pay attention to compatibility. Otherwise, you will end up buying the wrong product.
Spring Rate
Spring rate is defined as the quantity of load that moves the spring up to 1 mm. You will see the unit of kg/mm for this. The right spring rate ensures the stability of your car. Therefore, look for the right combination in terms of spring rate as well for your car.
Cost
Cost becomes a pretty important factor when you go out to buy something. Remember, good products do not have to be expensive. It would help if you looked for the best product at an affordable price. I usually keep the products with a higher price at a lower position on my list. Because I always suggest you find your desired features in the most affordable deal.
