BC Racing BR Series Coilovers for 13-15 Acura ILX/16-22 ILX

BC Racing BR Series Coilovers - 2013-2022 Acura ILX (DE1/DE2/DE3)

Acura had a problem selling you this car. They built it on the Civic's platform, gave it real Honda mechanicals, wrapped it in a genuinely nicer interior, and then had to charge you Acura money for it. So they did the one thing that makes this page necessary: they softened the suspension so it wouldn't feel like the cheaper car it's related to. That wasn't a hardware limitation. It was a brand decision about how your car should feel, made by people who never asked you, and it's the one you get to overrule.

There's A Better Car Under There

Nothing underneath your ILX is second-rate. The bones are Honda's, the platform is proven, and if you've got a 2013-2015 2.4L, you're literally driving the Civic Si's K24Z7 and six-speed with a nicer place to sit. That's the same motor the Si crowd cams and tunes and builds. Later cars carry the same chassis DNA with a more modern powertrain wrapped around it.

What none of them got was a chassis calibrated to match. Your suspension is tuned to keep an Acura buyer comfortable, which means it rolls a bit more than it should, takes its time settling, and stays polite right when you'd rather it got serious. That's a tuning choice sitting on top of good hardware. Change it and the ILX becomes what it always was underneath, a quick Honda that grew up and got a real interior.

The Rates, And Why They're Different By Year

Two specs here, depending on your car:

• 2013-2015: 6 kg/mm front, 7 kg/mm rear
• 2016-2022: 6 kg/mm front, 8 kg/mm rear

Small difference, but a telling one. BC didn't just carry the early kit forward and call it done when Acura facelifted the car, they re-tested it and specced a slightly stiffer rear for the later chassis. That's the whole difference between a company that measures each application and one that shelves a single spec across a model run.

And if 6 kg up front looks soft next to the 9 kg that goes under an old Integra or EF Civic, it isn't. Those cars use double wishbones, where the spring mounts inboard on the arm, so the wheel travels further than the spring does and a big chunk of rate never reaches the tire. They need a stiff spring on paper just to land somewhere sensible on the ground. Your ILX uses a strut front end, where the spring sits essentially on top of the wheel and nearly all of that rate gets there. Different geometry, different math, same destination.

Thirty Clicks Means You Decide, Not Acura

This is the whole point on a car like yours. You get 30 clicks of compression and rebound, adjusted together with one knob, about ten seconds a corner. Want it composed and quiet for the commute, exactly the way Acura intended? Wind it soft and it's the comfortable ILX you bought. Want to find out what this thing does with a chassis that's actually holding still? Firm it up on Saturday. The factory had to pick one setting and live with it forever. You don't.

Low, Without Undoing The Car

Ride height adjusts independently of spring compression, so you lower the car by moving the lower mount instead of crushing the spring onto itself. Your suspension keeps its travel and the damper keeps working. That matters more here than on a stripped-out track car, because the entire appeal of an ILX is that it's quick and it's civilized, and slamming one on collapsed springs throws the civilized half straight in the bin. Do it properly and you keep both halves of what you paid for.

Built To Be Kept

Mono-tube shocks with a linear piston and damping curve, so damping stays predictable through the whole stroke instead of getting strange at the extremes. Two-year warranty against manufacturer defect. And they're fully rebuildable, so when they eventually wear out you send them in for a refresh rather than buying another set. If you want to go further, custom spring rates, Swift springs, and custom valving matched to your rates are all available.
