Suspension bushings are some of the most highly stressed components of a vehicle. They provide movement and work as the joints between the frame and arms, struts and shock absorbers. Therefore, suspension bushings are able to affect the driving stability, ride quality, grip of traction, efficiency of the brakes and lifetime of tires. Once these bushings are worn, the vehicle will undergo an unpredictable and unsafe situation.
HARDENED RUBBER BUSHING
- Over 40 years experiences on rubber manufacturing
- HARDRACE exclusive rubber achieves a balance of hardness and flexibility
- Pre-Compressed procedure allows the bushings work under compressed
- pattern and enhances the durability of bushings
- High strength and anti-crack material extends the lifetime of rubber bushings significantly
- Viscosity between rubber and metal is about 2000kgs
PILLOW BALL BUSHING
- 10 years experiences on racing track
- Handling control and responsive steering is superior than harden rubber bush
- Precise control and solid suspension feel
- Inner bushing is made accurately with both high molecule plastic tube and specific metal alloy
- Soundless, high durability and reliability
- Outer bushing is combined with anti-dust boot, extend the life of the bushing
WHY FIT ADJUSTABLE ALIGNMENT ARMS?
The first benefit to fitting the Hardrace alignment arms is that they come with either an uprated bush or a rose joint. These uprated components minimise the movement in the arm in comparison to the standard items. You want minimal movement as any movement translates through to the steering in the form of vagueness and a lack of response the steering input. Each and every original bush has a degree of slop built into it to maximise the cars compliancy and minimise noise and vibration being passed into the cabin. This soft nature is exaggerated with age as the bush starts to deteriorate and their resistance to forces reduces leading to greater and greater deflection under load. As you turn the steering wheel the original bushes start to take the strain and in doing so compress. As they compress you have to compensate via the steering wheel as the original inputs effect is reduced via the bushes squashing.
STREET, PERFORMANCE, RACING and STANCE. Each category is produced with hardened rubber bushes or sealed pillowball joints that provide excellent stability and road response during high speed driving or hard cornering.
When you corner the cars body rolls. As the cars body rolls the outside wheels stand upright and then start to lean outwards. This is called negative camber. Conversely as you lower a car you tend to introduce additional static negative camber. The more you lower the vehicle the more negative camber is introduced. Negative camber is the wheel tipping in at the top.
You want sufficient static (i.e with the car stood at rest) negative camber to prevent positive camber under hard cornering but conversely excessive negative camber introduced when you lower a vehicle will lead to accelerated inside edge tyre wear, reduce traction for straight line acceleration and reduce the cars maximum braking ability. Hardrace adjustable camber arms allow you to set the camber correctly.
All cars have adjustable front toe built in as standard but most done have any provision for adjusting rear toe. Hardrace adjustable rear toe arms allow you to set the rear toe as required, be it toe in to generate heat more quickly and increase turn in stability or toe out to make the car more nervous and quicker to change direction for drifting or tight circuit work. Note that adjusting camber and castor also effects toe so you need the ability to reset toe if you go for camber adjustable arms.
Castor is the angle of the front strut when seem from the side of the vehicle. Adding castor increases dynamic camber, i.e. adds camber when cornering. This means you can run less static camber as the castor adds more camber when you need it. Having to run less static camber improves traction, reduces tyre wear and improves the cars potential braking abilities through improved grip. Adding castor also improves steering feel by making the steering heavier. This generates additional feedback so giving the driver more communication with what the tyres are doing. More information means you can driver closer to the edge more accurately meaning you can go faster. Hardrace adjustable castor arms allow you to adjust castor.
