Eibach Anti-Roll Rear Sway Bar for 16-26 Civic Si/Integra

Eibach Anti-Roll Rear Sway Bar - Honda Civic, Accord & Acura Integra

If there's one bolt-on that changes how a front-wheel-drive car feels in a corner, it's a rear sway bar. From the factory these cars understeer on purpose, meaning the front pushes wide when you ask for more than it wants to give. A stiffer rear bar is the classic fix. It wakes the back of the car up, kills that understeer, and gets the car to rotate and turn in like it actually wants to attack the corner. For a lot of enthusiasts, this single part is the best-feeling money you can spend.

Why The Rear Bar Transforms A Front-Drive Car

Here's the plain version of why this works.

A stiffer rear bar makes the back end resist body roll more, which shifts a little more work to the rear tires during hard cornering. That loosens up the tail just enough to cancel out the nose-heavy understeer these cars are built with.

The result is a car that rotates into the corner instead of plowing straight, turns in sharper, and feels alive and eager instead of safe and dull. You keep all the grip and stability, you just trade away the boring, understeer-first tuning the factory baked in.

2-Way Adjustable And Tubular

This bar is tubular and 2-way adjustable, and that adjustability is the whole point.

Set it to the softer hole for a mild bump in rotation that's friendly for daily driving, or move to the firmer setting when you want the car to really rotate on turn-in for backroads or autocross. You can tune the balance to your taste and change it whenever you like.

Building it tubular keeps the weight down while giving you the stiffness you're after, and at 22mm it's sized specifically for these chassis rather than being a generic bar that happens to fit.

The One People Buy On Its Own

Worth knowing: the rear bar is the one people most often run by itself, and for good reason.

Because these cars understeer from the factory, firming up just the rear gives you the biggest change in how the car feels for the least money and the simplest install. So if you're only going to add one bar, this is usually the one.

That said, pairing it with the front bar as the full kit gives you the most complete control over balance, flattening the whole car while letting you fine-tune front to rear. Either way, this rear bar is the piece that brings the rotation.

Start On The Soft Setting

This is a straightforward bolt-on, but respect what it does.

Start on the softer hole first, especially if this is your first adjustable bar, and get a feel for the extra rotation before you jump to the firm setting. A rear bar changes how the car behaves at the limit, and on a damp or cold road that shows up sooner than you'd expect. Ease into it, then firm it up once you know how the car responds.

Get your end links and mounts torqued properly and you're set.
