Hi guys,

 

what is the diffrence between KAD rear anti roll bar kit 3/4' bar or 5/8 bar'?

 

manny thanks, jure

[nicklouse]

1/8" diameter.

1/8" diameter.

 

what does that mean. as you may know already english is not my first lenguiche so can you tell me please tell me what is the diffrence between those 3/4 and 5/8 bar?

They are dimensions in inches. 5/8's is smaller than 3/4. Therefore I would expect that bar to allow more independent wheel movement whether this is a good thing I'm not sure. Depends on the application, wheel size, weight, spring rate and countless other factors I'm sure.

If you measure them one is 3/4 inch thick and one 5/8 inch. 1 inch is about 25mm, so 3/4" is about 18mm and 5/8 about 15mm. So 3/4" bar should be slightly stiffer meaning less body roll.

1/8" diameter.

Seriously! Considering how much you've been on the KAD website I'm surprised you've missed what they recommend each size for

Guys, it's a little repetitive watching everyone drubbing away on this lad. Let's give him a break?

Ok to be clearer 1/8 of an inch.

If you want to know which one is recomended for what use read the info on the KAD site it tells you. The last sentence of each description. If you can read that far.

For racing, the rear anti-roll-bar promotes oversteer. By stiffening up at one end, the road-holding is improved at the other end, thus a rear ARB transfers some of the road-holding to the front.

So on a race circuit, once the ARB has been used to promote turn-in oversteer early in the corner, the power can be applied without too much understeer developing so increasing the corner exit speed and thus the terminal speed down the next straight.

So the thicker ARB fitted, the more oversteer you will have. If you go with too thick an ARB the car will want to spin.

That is a bit of over-simplification, but the idea is right.

An ARB will allow braking later into the corner as the back will start to 'come round', then full power will balance it out and prevent the car from spinning.

Quite useless on a public road, of course, as you may not be able to corner on that sort of limit with the ability to use full power through a corner. It would not be conducive to keeping one's driving licence either  .

I hope this helps.

One is 19.1 mm and one is 15.9 mm , if that helps in metric .

I had assumed that the OP wanted to know what effect on the differences in vehicle dynamics would be with the two different sizes.

I assumed as well as that he did not understand imperial !

I wonder which he wanted.

But how it effects the handling and weight distribution depends on the the car and what it has been built for. You are definatly a dirt driver. And I don't mean that as the surface but the style.

In Hill climbing you often don't have the space to let anything slide.

And I agree Minis do like to slide. One reason the 10" wheel has stayed so popular. While Mini with 13s tended to roll over.
