Acura RDX: Suspension Modifications

This article applies to the Acura RDX.

First, let's get this out of the way - the Acura RDX isn't exactly a commonly hot rodded vehicle. There aren't a plethora of performance parts available for the crossover, because there just isn't a ton of demand for them. But does that mean that you are out of luck when it comes to improving your handling and performance? Of course not, because parts do exist that can help you meet those goals. Here are the most popular, and most effective ways to improve your suspension's performance.

Suspension Modifications

While there aren't a ton of manufacturers that make performance suspension parts for the RDX, there are a few that are currently churning out quality parts. Like many other vehicles, coilovers are one of the better ways to improve the looks and performance of your RDX, as are a fresh set of wheels and tires. Let's take a closer look at what's available and how they can improve your RDX in a number of ways.

Coilovers

DIY Cost – $500-$2,500

Professional Cost – $600-$3,000

Skill Level – Moderate; fairly easy to install with basic tools, but can be time consuming and old parts can prove difficult to remove.

Until just a couple of years ago, RDX owners who wanted fully adjustable coilovers for their cars were out of luck. That is, until BC Racing came along to save the day. Their complete coilover kit is a beautiful, custom piece that features easily accessible adjustment knobs that allow you to fine tune your compression and rebound, as well as the ride height. This makes them an excellent choice for street or track.

Eibach also makes separate springs that can be (should be) paired with your choice of lowered shocks if you don't care about having the ability to make adjustments. These springs lower the front around 1.3" and the rear around 1.0". They are a little firmer than stock springs, which gives you a factory like ride with better handling characteristics.

Wheels

DIY Cost – $500-$2,000+

Professional Cost – $600-$2,000+

Skill Level – Easy; anyone can install with basic tools and mechanical skills.

When most people think about the benefits of aftermarket wheels, they only consider the great looks that these hunks of metal provide. But wheels can have a big impact on your handling, depending on the diameter, width, and weight of the wheels you choose. Lighter, wider wheels can have a big impact on your grip in the corners.

One company that provides RDX owners with some great options is WedSport. They use a special process to cast wheels in a manner that makes them almost as strong as a more expensive, forged wheel. WedSport has done their homework in regards to fitment as well, meaning that you don't have to worry about things like backspacing and whether or not your new wheels will fit your ride just right.

Tires

DIY Cost – $500-$2,000+

Professional Cost – $600-$2,000+

Skill Level – Moderate; can be mounted at home, but mounting and balancing are best left to a professional.

Unlike wheels, coilovers, and other various suspension parts, tire options are plentiful for the RDX. Your choice will largely boil down to what sort of climate you live in and how you drive your car. Most opt for all season tires that give them the best all around performance in various conditions, but if you live in a dry and warm climate, you might opt for summer performance tires instead. Or, you can always keep an extra set around and swap them as the seasons change.

One of the most popular tires for the RDX is the Nitto Motivo, a tire that is produced in sizes that fit the RDX well. These tires are all season by design, but are modeled with high performance in mind for dry and wet conditions. They also have a nice, aggressive look that pairs well with aftermarket wheels and a suspension drop.
