Step-by-step guide to installing the Precision Works rear subframe brace and sway bar end links on 2016+ Civic models, with common mistakes to avoid.
Quick Answer
Install the Precision Works rear subframe brace and sway bar end links on your 2016+ Civic by lifting the rear, removing the stock end links, bolting the brace and new links in place, and torquing everything to spec. The kit includes all necessary hardware, and the job takes about two hours with basic hand tools.
Why the Rear Subframe Brace and End Links Work Together
The Precision Works rear subframe brace and sway bar end links are designed to be installed as a set. The brace reduces chassis flex by tying the rear subframe together, while the new end links replace the factory rubber units with stiffer connections that transfer sway bar force more directly. Together, they stiffen the rear suspension and improve cornering response.
This kit is built for 2016-2021 Honda Civic FC and 2017-2021 Civic Type R FK8. The brace is CNC-machined from 6061 aluminum, and the kit includes the subframe brace, end links, spacers, and hardware. You can choose your preferred color for the brace, but all versions fit the same way.
Tools and Preparation
You will need a floor jack, jack stands, a socket set with extensions, a torque wrench, and penetrating oil for stubborn bolts. The car should be on level ground and securely supported before you start.
The kit includes all necessary spacers and hardware, so you do not need to source extra bolts. However, it is a good idea to have a wire brush on hand to clean the subframe mounting points before installation.
Installation Steps
- Lift the rear of the car: Use a floor jack at the center rear jacking point and support both sides with jack stands. Ensure the car is stable before working underneath. Never rely on the jack alone—always use jack stands.
- Remove the stock sway bar end links: Spray the end link nuts with penetrating oil and let it sit for a few minutes. Use a socket and wrench to remove the nuts, then pull the end links free from the sway bar and the knuckle. If the stud spins, hold it with a second wrench to avoid rounding the nut.
- Clean the subframe mounting points: Use a wire brush to remove rust, dirt, and old thread locker from the subframe holes where the brace will mount. This ensures a flat, clean surface for the brace. Skipping this step can cause the brace to sit unevenly and loosen over time.
- Position the rear subframe brace: Hold the brace up against the subframe and align the holes. Install the supplied bolts and spacers hand-tight first, so the brace can shift slightly for alignment. Start all bolts before tightening any of them to avoid cross-threading.
- Tighten the brace bolts to spec: Use a torque wrench to tighten the brace bolts to the manufacturer's specification (typically around 80 ft-lb, but check the included instructions). Tighten in a crisscross pattern for even load. Over-tightening can strip the subframe threads; under-tightening can cause rattles.
- Install the new sway bar end links: Attach the Precision Works end links to the sway bar and the knuckle, using the supplied hardware. Torque the nuts to the factory specification (usually 28-35 ft-lb). Ensure the end link is oriented correctly—check the instruction sheet to avoid binding.
- Lower the car and re-check torque: Lower the car to the ground and re-check the torque on all bolts after the suspension settles. This ensures everything is secure under load. Re-torquing after a short test drive is a good habit to catch any loosening.
