Wolftech bushes is a direct replacement for the standard rubber bush. Its properties are stiffer then rubber and allow less flex. They are also less susceptible to heat, meaning that the bush is mounted near the engine, exhaust or brakes that they will stay firm rather than becoming soft like a standard rubber bush.

Wolftech bushes are the easier option to install. Once the standard rubber bush has been pressed out, the Wolftech  is then inserted itself or  in two halves from either side of the component with an insert through the centre for the bolt to contact with.

The stiffer compound of the Wolftech reduces the amount of flex at each connection and therefore, decreases the response time of the chassis, resulting in the car changing direction faster and making the driver have more feel through the steering, connecting them to the car and circuit better.

Difference between polyurethane and rubber bushings :

The general answer to this question is rubber bushes will give a smoother, quieter, and more comfortable ride. In contrast, polyurethane will increase the handling capabilities of a car along with driver feedback. 

Do I use Wolftech polyurethane ?

Manufacturing costs and the desire to make cars as comfortable as possible are the main reasons rubber bushings are found on most road-going vehicles. Rubber bushings will help absorb harsh bumps and dampen road noise.

These are all properties that manufacturers will choose when selling cars designed to be used daily and on long journeys. However, suppose you are building or modifying a vehicle to be performance-focused, comfort and noise will be overshadowed by the all-out handling properties and road feel found with Polyurethane bushings.

Improve handling:

Your car's suspension components are all connected by the bushes, meaning that spending time getting the perfect alignment settings on your vehicle will be wasted when using rubber bushes, as they allow more unwanted movement of the suspension arms.

Polyurethane bushes will hold their shape much more efficiently under intense cornering load, keeping your alignment exactly where you want it.

Not only will your alignment stay truer, the feeling and feedback you receive as a driver will increase hugely. Rubber bushes are designed to dull down the impact of the road for comfort. In contrast, on the track, you will want to feel everything that is going on underneath the car, giving more driver feedback and awareness of conditions and track surface.

The reduced unwanted movement of the steering arms will provide a much more direct steering feeling, again always giving the driver more information.

Longevity of Polyurethane:

After five years, some different types of bushes may need to be regreased. However, many kits now are so good that after being greased during installation, they have a good chance of outlasting the car's life.

As with any component under stress on your car, it will still be worth doing regular visual inspections, making sure the bushes are still correctly seated, and all the bolts are still done up to the manufacturer's specs.

Generally, on MOTs, play or movement in the bushes will be picked up on the inspection; however, there are some visual checks that you can do. Most conventional rubber bushes are constructed from a metal outer and inner bonded in place.

Over time this can separate, and the bush will become ineffective. In addition to this, you will see if the bushes are perished or cracked on a visual inspection. Cracking or perished rubber will render them unusable or substantially softer.

WOLFTECH Polyurethane Bushes:

Once the domain of the military and racecars, polyurethane bushings did not become widely available until the 1930s. As they don’t rot or deteriorate, they often outlast the vehicle they’re put on. For anyone looking to upgrade their suspension, poly bushings are a great choice. Here’s how poly stacks up against rubber.

Ride Quality:

Due to their hardness, polyurethane bushings often lead to a bumpy ride. Since they’re not as good at dampening, passengers are also subjected to a lot more noise and vibration.

Hardness:

Polyurethane bushings are much harder than rubber ones. Though that doesn’t mean they’re the hardest ones available. That honor goes to the aluminum suspension bushings used by racecar drivers.

Lifespan: 

Because they’re harder, poly bushings cope a lot better with the demands of the suspension system. They’re also resistant to UV, oils, road chemicals, rust, and heat. Often outlasting the vehicle they’re installed on, polyurethane bushings are usually covered by comprehensive warranties.

Squeaking: Contrary to popular belief, polyurethane suspension bushings don’t HAVE to squeak.  They’re just more likely to do so. This all comes down to how they’re made. While rubber bushings are chemically bonded to their housings, poly ones are assembled mechanically. This means they have room to move, rub, and jostle against their sleeve. If not properly maintained, this can lead to squeaking.

Installation:

A hydraulic press is usually not required to install a polyurethane suspension bushing. Once you’ve learned how to remove the old rubber bushing, installation is an easy two-step process.

Maintenance: 

Unlike rubber suspension bushings, poly ones need to be greased every three to five years.

Feel of the Road: Polyurethane bushings help the vehicle feel like an extension of the driver. The bumps and potholes become more pronounced. Though this is a turnoff for some, others feel that it makes them better drivers.

Performance: 

Since they don’t flex as much, poly suspension bushings can make the entire suspension system more efficient. This makes turning and cornering easier.

Price:

Poly bushings are the cheaper of the two.
