Bushings & Mounts

Does the engine vibrate through the whole cabin, or does the rear end feel loose in fast corners? Worn or soft bushings create movement exactly where you want control. In this category we bring together suspension bushings, engine, transmission and differential mounts, strut top mounts and subframe bushings for daily drivers, trackday cars and projects alike.

What bushings and mounts do

Bushings and mounts sit between control arms, subframe, body and drivetrain and determine how much the parts can move relative to each other. OEM rubber parts dampen vibrations but can give under acceleration, braking and cornering, especially when worn. Stiffer bushings and mounts can keep wheel alignment more precise and reduce engine and gearbox rock, but typically transmit more noise and vibration into the cabin.

How to choose bushings and mounts

• Use: For daily driving, comfort often matters most, while stiffness can be more important for trackdays or a project with more power.
• Material and hardness: Rubber, polyurethane and elastomer behave differently, and the actual hardness depends on the product.
• Location: Engine mounts and transmission mounts affect vibrations and drivetrain movement, while suspension bushings affect steering feel and wheel alignment.
• Car model: The parts are model-specific, so check model year, body style and position – front or rear, left or right.

Brands in this category include Superpro, Prothane, Energy Suspension, Innovative Mounts and Whiteline. Replacing several bushings on the same axle typically gives more consistent behaviour than replacing one at a time. After fitting suspension bushings, the wheel alignment should be checked. Some polyurethane bushings must be greased during installation and can squeak over time, so follow the manufacturer's instructions. If you are also changing dampers or springs from suspension components, it pays to match the parts as a whole.

Frequently asked questions

Should I choose polyurethane or rubber?

Rubber typically dampens noise and vibrations best, while polyurethane and other stiffer materials can give more precise steering and less movement. The choice depends on how much comfort you are willing to give up and on the specific product's hardness.

How can I tell if the engine mount is worn?

Typical signs are strong vibrations at idle, clunks when pulling away or shifting gears, and visible cracks in the rubber. The symptoms can also have other causes, so inspect the mount before ordering a new one.

Can bushings and mounts cause problems at the vehicle inspection?

It depends on the product and the car. Check for the specific part number whether any requirements apply or documentation is included, and make sure the wheel alignment is correct after fitting.

Can I fit the bushings myself?

Some engine mounts can be fitted with ordinary tools, while control arm bushings often require a press. Strut top mounts require a suitable spring compressor. Have the wheel alignment checked afterwards.
