Powerflex Polyurethane Bushes

[Phalanx]

Just want to ask whether anyone has changed to the above? Comments?

Hi! there, Phalanx,

 

FR is good for the bushings, especially, it's easy to install. But then, it's not cheap. for my Alfa75ts, it'd cost about S$300 for the bushes.

Hello,

 

What's FR? How long does the bushes usually last, considering factors such as the condition of sg's roads and all?

[Turbobrick]

I have a set of Powerflex bushings in my lower A-arm joins, nothing to shout about but they'll definitely outlast the car's lifespan.

Hi! there, Phalanx,

 

FR = field report, i.e. those who are using it.

 

I've never used them, so not sure how long it would last. If from hearsay, sg road condition, it should last a long time. If the car is driven like an Italian, brake-pads will last longer.

like to know where to get a complete set?

 

intend to change the whole car since 10yr coe already renewed and a few of them are already worn ...

Hi! there, Shagmobil,

 

You'd need to check whether they have it for your car.

Hi! there, Shagmobil,

 

Disregard the last message. The link is wrong. You'd have to use a search engine to look for it.

What is this for? Just curious.

Bushing for suspension and engine, primary purpose is to hold metal to metal.

Ok.... still dunno what u mean.. but how do i know whether i need that for my car?

The stock bushings are solid rubber or metal encasing rubber type, wear and tear will cause the stock bushings to fail. Polyurethane bushings have almost lifetime durability and are much stiffer for performance.

Hi! there, Guyver,

 

Every modern car has bushings. You know what springs & shock absorbers, right?

 

Bushings act the same way as those, the difference is, it's to connect 2 linkage, heard of multi-link suspensions? So to link 2 pieces of metal, be it metal rod or sheet, a rubber bush is smaller, usually round.

 

Do you know what an engine mounting is? It's to connect the engine to the engine bay, if it's round, they would call it a bush, but it's not, so it's called a mounting.

 

An example :-

Of course, of my car, the legendary design of Alfa Romeo 158/159 Alfetta.

 

From the front,

 

The anti-roll bar, Americans call it the sway-bars, connected to a link bar to the lower A-arms, which Honda advertise as double-wishbone, of course Alfa has it first.

 

There are 2 bushings at the link bar, so 4 pieces for the anti-roll bar. The lower A-arm has 2 bushings that's connected to the chassis at the torsion bar with a ball-joint that joins to the knuckle that holds the front brake assy & tyre & wheels.

 

The torsion bar, which most of you are not familiar with, acts the same way as the springs at your shock absorber. The advantage of the torsion bar is the lowering & raising of the front of the car is by turning the torsion bar until the desired height, so no springs to cut.

 

So, Honda advertise their double-wishbone as designed from F1 race cars. Here, Alfa Romeo has the upper A-arm, to complete the set-up. It's not as designed from the race cars, it really, and truly is from the Alfetta 159/159 race car that won the first World Championship. There's 1 bush that's attached to the chassis and 1 ball-joint attach to the knuckle.

 

There's supposed to be 2 pcs of bushings at the end of the castor rod. I've done away with that, instead replaced it with a ball-joint from an older Alfa, the Bertone-designed Giulia GTV, a family member of the all-conquering Alfa Romeo GTA of the 1970s, others will call it the terror of the race-tracks around the world, as they won't a prayer of winning if a GTA is taking part.

 

So, unless you have a multi-link suspension, you shouldn't have as many bushes as my car.

So stiffer means more vibration?

Think mine has that....saw it before.... i think..... anyway.. thanks...
