Product Description

The Progress 62.0103 rear sway bar is a serious handling upgrade for the Acura RSX DC5 and early Civic Si EP3. Its 24mm solid bar adds rear roll stiffness to help reduce body roll, keep the tires planted through corners, and make the car feel more responsive when you turn in.

Unlike a basic rear sway bar kit, this one includes a reinforcement brace and HD adjustable ball-stud end links. The brace supports the mounting area, while the adjustable links make it easier to install the bar without unwanted preload. Two adjustment settings let you choose how much rear roll stiffness fits your setup.

For street driving, autocross, or track use, this is a straightforward way to sharpen the chassis without changing the car's ride height. It is especially useful for RSX and EP3 owners looking to reduce the factory understeer feel and get a more neutral cornering balance.

Setting Up a Rear Sway Bar on Your RSX or EP3

Start with the softer adjustment setting if your car is mostly street-driven or you are adding the rear bar to an otherwise stock suspension. The firmer setting adds more rear roll stiffness and can help the car rotate more easily, but it can also make the rear feel more active in quick transitions or rough corners.

It is also good to set the adjustable end links with the car sitting at its normal ride height. That helps avoid preloading the bar. If your RSX or EP3 is lowered, inspect the end-link angle and the clearance around the bar, exhaust, and suspension components before tightening everything down.
