Subframe Bushing with Fitting Position Front, Rear for 2016 Subaru BRZ Series.HyperBlue

Nolathane subframe bushings help control movement where your Subaru BRZ's subframe meets the body. The subframe, also called a crossmember or cradle, is the frame that carries the suspension arms and, on many cars, the differential. Each subframe bushing sits between that frame and the body, isolating noise while holding everything in position.

When subframe bushings soften or tear, the whole subframe can shift under power and braking, taking the suspension geometry with it. Our range focuses on polyurethane insert sets for rear subframes, which reduce that movement without replacing the factory bushings. Each listing shows the position, design, and vehicles each set fits.

What the Subaru BRZ Subframe Bushings Control

Many modern cars, especially those with independent rear suspension (IRS), mount the suspension to a separate subframe rather than directly to the body. The control arms bolt to the subframe, and on rear-wheel-drive cars the differential usually hangs from it too. The subframe is then bolted to the body through large bushings at each corner.

Those bushings have two jobs. They isolate the cabin from road, gear, and differential noise, and they keep the subframe located so the suspension mounted to it stays where the engineers intended.

Factory subframe bushings are usually soft, chosen for a quiet ride. That softness lets the subframe move under load. When you accelerate hard, the driveline twists the subframe. When you brake or corner, it shifts sideways or fore and aft. Because the control arms are mounted to the subframe, that movement changes rear toe and camber on the fly, and the rear end doesn?t behave as predictably as it should.

Subaru BRZ Front and Rear Subframe Mount Positions

Subframes are used at both ends of many vehicles, but the rear is where movement causes the most noticeable problems.

Rear Subframe Mounts

On IRS cars, the rear subframe carries the rear suspension and often the differential. Movement here shows up as rear steer, where the rear wheels change direction slightly under load, and as wheel hop during hard launches. Rear subframe bushings are the most common upgrade for drivers chasing a more stable, planted rear end.

Front Subframe and Engine Cradle Mounts

At the front, a subframe or engine cradle often carries the lower control arms, the steering rack, and sometimes the engine mounts. Worn front subframe bushings can contribute to vague steering and clunks, though the rear subframe is usually the priority on performance cars.

Signs of Worn Subframe Bushings on Your Subaru BRZ

Subframe bushing wear often feels like a problem somewhere else in the driveline. Watch for:

• A clunk on take-off, during gear changes, or when lifting off the throttle
• Wheel hop under hard launches
• A vague, shifting feel from the rear end in corners
• Rear toe that won?t stay in specification after an alignment
• Visible tearing or separation of the factory bushings
• Fluid weeping from fluid-filled factory bushings

The clunk is often the first sign. It happens as the subframe shunts forward or back when the driveline load changes.

Full Replacement and Bushing Inserts for the Subaru BRZ

There are two ways to deal with subframe movement, and each has its place.

Full replacement means pressing out the factory bushings and fitting new ones. It?s the most complete fix and the only option when the factory bushings are torn or separated. It usually involves lowering or removing the subframe and using specialized press equipment, such as a subframe bushing removal tool, so it?s a substantial job.

Insert sets take a different approach. Many factory subframe bushings are voided, meaning they have open spaces molded into the rubber to make them softer in certain directions. An insert set fills those voids with polyurethane, reducing how far the bushing can deflect. Inserts are usually fitted without pressing out the factory bushing, so the job needs far less labor.

The key condition is that inserts depend on the factory bushing still being bonded and intact. If the rubber has torn away from its sleeve, inserts won?t fix it, and full replacement is the right path.

How Polyurethane Inserts Reduce Subaru BRZ Subframe Movement

A voided factory bushing can move a long way before the rubber starts to resist. Filling those voids changes that. With polyurethane inserts in place, the bushing meets resistance much sooner, so the subframe moves far less under acceleration, braking, and cornering.

The inserts limit deflection without solid-mounting the subframe. The factory rubber still provides some isolation, so the result is a firmer, more controlled subframe without the harshness of a fully solid mount.

Polyurethane is well suited to the job. It resists oil, grease, ozone, and weathering, so the inserts hold their shape under the car, and its hardness is chosen to firm up the bushing without transmitting excessive vibration.

Choosing Subframe Bushings for Your Subaru BRZ

Choosing the right set starts with the factory bushing. Each listing shows the options and fitment details.

Factory Bushing Type

Inserts only suit voided factory bushings that are still intact and bonded. Inspect the factory bushings first. If they?re torn or separated, they need full replacement instead.

Front or Rear Position

Check whether you?re working on the front or rear subframe, and match the set to that position.

Vehicle Search and Listing Options

Use the vehicle search to find the sets that suit your Subaru BRZ. Each listing shows the position and the factory bushing design it?s made for.

Fitting Subframe Bushing Inserts on Your Subaru BRZ

Subframe hardware is safety-critical, so qualified fitting is recommended. The general process looks like this:

• Support the vehicle safely on stands
• Inspect the factory bushings, and fit inserts only if they?re intact
• Clean dirt and debris out of the voids
• Lubricate the inserts if the listing specifies it
• Push the inserts into the voids until they?re fully seated
• Check that the subframe bolts are tightened to specification
• Have a wheel alignment carried out if the rear geometry was disturbed

Check the bolts again after the first drive.

Subaru BRZ Subframe Bushing Limitations and Trade-Offs

Subframe bushing inserts are an effective upgrade, but they have limits:

• Inserts can?t repair a torn or separated factory bushing, which needs full replacement
• More road, gear, and differential noise reaches the cabin
• Inserts don?t fix worn control arm or differential bushings elsewhere in the suspension
• They suit voided bushing designs only

Compliance and Insurance

Make sure your Subaru BRZ meets the inspection requirements of the state where it?s registered, and let your insurance company know about any suspension modifications.
