If you're looking to fix that monster truck wheel gap, grabbing a set of progress rsx coilovers is easily one of the best ways to get your Acura sitting right while actually improving how it corners. The RSX, or the DC5 as the enthusiasts call it, is a legendary chassis, but let's be real—the factory suspension wasn't exactly designed with modern performance standards in mind. After twenty years on the road, most stock struts are tired, bouncy, or just plain blown out.
Upgrading your suspension is usually the first big step in any build. You want that aggressive stance, sure, but you also don't want to feel every pebble on the road like it's a structural threat to your spine. That's where the Progress Group comes in. They've been in the Honda and Acura game for a long time, and their Series II coilovers have earned a bit of a cult following in the RSX community.
Why the RSX Needs Better Suspension
The Acura RSX is a bit of a weird bird when it compares to the Integras that came before it. Instead of the double-wishbone setup that made the DC2 so famous, the DC5 uses a MacPherson strut front end. If you've spent any time on the forums, you know that lowering a MacPherson strut car can be tricky. If you go too low without the right geometry, your handling actually gets worse—you run into issues with the roll center and the steering rack angle.
A lot of the "budget" coilovers you see on eBay or Amazon are just universal dampers slapped into a bracket that fits the RSX. They don't take the car's specific geometry into account. Progress RSX coilovers are different because they're engineered specifically for this chassis. They aren't trying to be a "one size fits all" solution. They focus on maintaining a functional ride height while stiffening things up just enough to make the car feel planted in the turns.
What Makes Progress Different?
When you unbox a set of these, the first thing you'll notice is the build quality. They aren't flashy with neon colors or giant stickers. They look like serious pieces of hardware. But the real magic is in the internal valving and the spring rates they choose.
Spring Rates and Valving
Progress tends to go with spring rates that make sense for a car that actually gets driven on the street. A lot of competitors throw 10k or 12k springs on their coilovers because "stiffer is better," right? Not really. If your springs are too stiff for your valving, or too stiff for the weight of the car, you're just going to skitter across bumps instead of absorbing them.
The progress rsx coilovers usually come with a spring rate that balances daily comfort with a significant reduction in body roll. It makes the car feel much more "point and shoot." When you turn the wheel, the car reacts instantly instead of leaning over and thinking about it for a second.
The Importance of the Steering Arm
One of the biggest headaches with RSX suspension is the steering arm location. On the DC5, the tie rods connect directly to the strut body. If a manufacturer gets the height of that bracket wrong, you end up with massive bump steer, which is that terrifying feeling of the car darting left or right on its own when you hit a bump.
Progress spends a lot of time ensuring their brackets are welded in the correct spot to keep your steering geometry as close to factory specs as possible. It's a small detail that makes a massive difference in how the car feels when you're carving a canyon or just trying to stay in your lane on a crappy highway.
How They Feel on the Road
I've ridden in RSXs with everything from cut springs (please don't do that) to $3,000 professional race setups. The Progress Series II falls into that "sweet spot." It's firm—don't get me wrong, you're definitely going to know you're on aftermarket suspension—but it isn't harsh.
It takes the "floaty" feeling out of the highway ride. If you've ever felt like your RSX was a bit disconnected at 70 mph, these will fix that. The car feels glued to the asphalt. On a twisty backroad, the difference is night and day. You can carry more speed through the corners because you have the confidence that the tires are staying in contact with the ground.
Another thing people love about these is that they're relatively quiet. A lot of cheap coilovers start clunking and popping after a few thousand miles. Because Progress uses high-quality bushings and well-designed top mounts (or works with your factory ones, depending on the kit), you don't get that "old school bus" soundtrack every time you pull into a driveway.
A Few Things to Watch Out For During Install
Installing progress rsx coilovers isn't a nightmare, but you should definitely set aside a full Saturday for it if you're doing it on jack stands in your driveway. The rear suspension on the RSX is pretty straightforward, but the front can be a bit of a workout.
Since the front struts are part of the steering assembly, you're going to be messing with your tie rod ends. This is a great time to check your ball joints and bushings, too. If those are shot, new coilovers aren't going to fix your handling problems; they might actually make the vibrations from worn-out bushings more noticeable.
Also, remember that any time you change the ride height, you must get an alignment immediately. You can eyeball it to get to the shop, but your toe settings will be all over the place after swapping struts. If you skip the alignment, you'll chew through a set of front tires in about a month.
One thing I really like about the Progress setup is that the height adjustment is separate from the spring preload in many of their designs. This means you can lower the car without sacrificing the travel of the shock. You aren't just "squishing" the spring to get the car lower, which is how the cheap kits do it.
Is It Worth the Money?
Let's talk turkey. There are cheaper options out there. You can find coilovers for $500 all day long. But you get what you pay for. If you plan on keeping your RSX for more than six months, spending the extra bit for progress rsx coilovers is a smart move.
It's an investment in how much you enjoy driving the car. There's nothing worse than "modding" your car only to realize you hate driving it because the ride is too bouncy or the steering feels broken. Progress has a reputation for durability, too. These units are built to handle the salt, grime, and heat of daily driving without seizing up or leaking after the first winter.
Final Thoughts on the Setup
If you're a track rat looking for a dedicated time-attack setup, you might want something with external reservoirs and 32-way clickers. But for 90% of RSX owners—the ones who want a lower car, a better look, and much better handling for the street and the occasional autocross—Progress is hard to beat.
They strike a balance that's difficult to find. They aren't over-engineered to the point of being confusing, and they aren't under-engineered to the point of being dangerous. You just get a solid, well-made piece of American-engineered hardware that makes your Acura drive the way it should have from the factory.
So, if you're tired of that wheel gap and you want to actually enjoy the corners again, definitely take a look at the Progress kits. They've been a staple in the RSX world for a reason, and once you take that first corner with them installed, you'll understand exactly why. Just make sure you've got a good set of tires to go with them, because you're going to find yourself taking turns a whole lot faster than you used to.
