H&R ARBs Adjustable fitting?

[geordie56]

Hi, i am getting the H&R arbs and just want to know the holes nearer to the outside or nearer to the inside which makes it stiffer? And is it the same for both the front and the rear? Cheers.

inner holes are stiffer ones.   its like using a lever, the longer it is the easier to lift or bend

the  hole at the end of the bar is the softer setting F&R

I would like to know the same thing! Im literally in the middle of fitting these myself. Mine were a second hand set and I could clearly see the ones previously used were the ones closest the end

Spot on cheers for your help guys!

You're all wrong.  The bolt hole which is the FURTHEST away from the pivot is the 'stiffest' setting.  Search for the Whiteline adjustable ARB pdfs . . . .

Balls!!

i spke to eibach before adjusting mine and they said the opposite to you.  anyone go the link to the whitleine pdf, i cant be arsed searching lol

Think about the length of lever needed to undo f-ing tight wheel bolts.  With a short 12" bar, you probably won't be able to undo them - but with a 30" breaker bar, they will be easy.

At the end of the day - they are ANTI-roll bars, and use a simple 'lever principle' to counteract differential torque (twisting force) along the length of the ARB.  So the bolt hole closest to the centre-line of the ARB will be less able to cope with the torque than the bolt hole furthest away.

www.whiteline.com.au/vehicle_swaybars.php is a starter for 10.

that to me backs up what myself and everyone else have said  by using the inner hole, you have less 'leverage' from the bolt to the centre line so it will roll less as its harder to bend.

If you use theouter hole the 'lever' is longer so it would 'bend so to speak' easier and thus roll more.

I stand to be corrected, no one is right all the time,  but the above makes sense to me, eibach also confirmed it as have others.  ill have a look through the PDF after i pick the wife up from work

I'm still thinking the inner hole will make things tighter. :s

[gazbutS3]

thatst the way I saw it, the outer hole gives a larger lever so can bend the bar so give some roll, inner hole less leverage can't bend the bar so less roll
 could be wrong but I did ask quite a few people, one with vast racing experience , and was told by everyone the outer hole is softest setting

[jabbalad]

the further out the hole is the less of an effect the arb has!

So like others have said the inner hole is the stiffer setting!

(i could be wrong but that would mean all the setup work on race cars and running my own race cars for the last god knows how many years has been completely wrong!)

BUMP,

I'd like to know the outcome of this discussion , so we know if we have our ARB's set where we think we have them

Anti-roll bars work on counteracting torque reaction.  IE, they are 'reactive' rather than 'proactive' - so you need to reverse your logic.  If you have 'less leverage', then you simply have a less efficient, therefore less hard anti-roll bar.

I can't scan my Whiteline docs (dead desktop puter), but they clearly state that the OUTER holes are for the hardest (ie stiffest) setting.
