Best Anti Roll Bar kit?

[GLIDN]

I too have the adjustable Whiteline anti-roll bars - front soft, rear hard.  I'd happily recommend them.

And to the Kiwi who said they have difficulty getting stuff - Whiteline are made in Australia, so fairly local! 

lol, yeah I know No whiteline products in NZ, no stock. Minimum 5 -6 weeks wait.
Ended up getting an APR from APR NZ in little under 1 week. Pretty impressed I must say.

Hello all,

I'm new on this board for just a few days and I'm pleased by this forum
an the technical competence of it's members.

 

I was looking for the best ARBs some time ago and made a posting like
this on a german forum. So let's begin:



Most of You know about the advantages:

- reduced roll
- reduced loss auf camber when cornering
- better Handling
- more clearence when cornering hard with ultralow suspension
- just a very small amount of loss of comfort



Most AR bars of PQ35 platform cars do fit the golf except 4-motion vs. fwd.



stock GTI/Touran etc.:




H&R:




APR:




Hotchkis:




Attention: most OEM are tube types, thickness in mm. Most tuner bars are solid
(except APR/Hotachkis).



I made a table of the bars I know of, but there may be some more:


Type:  diameter front (x thickness) / diameter rear (x thickness)


OEM:

A3 Ambition/S-Line: 22,5 x 3,5 / 20,7 x 2,8

Golf V GTI:  23,6 x 3,5 / 21,7 x 3,0

Golf V R32:  22,0 massiv / 21,7 x 3,0  (4-motion)

Golf VI GTI:  23,6 x 3,5 / 21,7 x 3,0 PR-0BF oder 21,7 x 3,6 PR-0BM (DCC?)

Golf VI R:   22,0 massiv / 21,7 x 3,6  (4-motion)

Scirocco R:  23,6 x 3,5 / 21,7 x 3,6

Touran:       23,0 massiv / 21,7 x 3,0

Passat R36:   23,6 massiv / 21,7 x 3,6 (4-motion)

Sharan model 2011: 24.0 solid / 20.0 solid


tuning:

H&R 'normal':          26 / 22 mm

Eibach AntiRoll:       26 / 23 mm

KW clubsport:          26 / 23 mm

H&R 'extra-dick':     28 / 24 mm  (there is a 28 mm rear at AWE)

H&R  4-motion:     25 / 25 mm  

Whiteline:             24 / 24 mm  

Neuspeed:             25 / 25 mm  (without TÜV)  

APR/Hotchkis:      27 / 27 mm  (tubular, without TÜV)  


KW CS sould be identical to the Eibach AR kit, just yellow instead of red, so look
at the pricing or choose the colour you like.

Some data about the torsional resistance:


inner hole   (short arm)
outer hole (long arm)


- OEM front GTI
  diam. 23,6 x 3,5 mm - tube

c = 65,6 N/mm

- H&R front
  diam.  28 mm - solid

c = 172 N/mm Mitte  (~ 156 N/mm outer bzw. 188 N/mm inner)


- OEM rear GTI
  diam. 21,7 x 3 mm -  tube
  
c = 59,5 N/mm

- H&R rear
  diam. 24 mm - solid
c = 122,7 N/mm Mitte  (~ 109 N/mm outer bzw. 139 N/mm inner)


As You see torsional resistance ist twice as hard on the rear and 2 1/2 to3 x
on the front.

In conjunction with stiffer springs roll is half than OEM, with TT arms maybe even less.

 

Whiteline has a helpful table to compare the diameters on their website !!


Some my be interested in the stiffer OEM bars (e.g. Sharan), but be aware that they're
only slightly harder than stock GTI bars. If You wanna feel a real difference buy the
more expensive ones with 25 to 28 mm.

The Sharan rear bar maybe an option when you just want to change the rear ARB because
it's relatively cheap and changing rear is easy.



I'd recommend the 28/24 H&R and the Whiteline 24/24. H&R Advantages: TÜV, teflon liner
bushes, forged ends, quick turn in response.
The Whiteline offer a more neutral balance, triple adjustment, better traction and since 2011
they come with TÜV certificate as well.

Hotchkiss=APR, same bar, APR just repaints it 

Autotech is also hollow, and IMO worth considering 

[Janner_Sy]

All the eibach ARBs are now hollow as well

[Carrera2RS]

Anyone know what stiffness the VWR bars are ?

[the bruce]

The VWR suspension comes from KW, so the ARBs as well?

H&R bars can be bought separately. You don't have to buy kits.
I am using 26mm front and 24mm back. My setup is hard/hard.

LE: As I know each sway H&R sway bar has TUV (not only the kits). Am I wrong?

Where did you get these? Could you please tell me the figures for 26/22?

[Carrera2RS]

If you are comparing solid, with solid then from my engineering memory then take (26/28)^4 x 172 should work (I Haven't got a scientific calculator at hand) the stiffness is the the 4th power. This is bar only and not real world as the bars will distort and twist though the arms, links etc dealing with that stiffness.

Simpler is to forget the actual value and look at increases stiffness

[fuscobal]

I'm using BSH 27mm on the rear and H&R 26mm in front, both of them set on soft. Thicker rear bar will help you rotate the back on very tight corners but on tracks like Nring I think thicker front (like most manufacturers kits are) is safer at high speed corners !

[the bruce]

H&R bars ....
 As I know each sway H&R sway bar has TUV (not only the kits). Am I wrong?

Yes an no. The ''Teilegutachten'' (TÜV) allows the H&R front ARB to be mounted
in conjuction with the stock one at rear. But H&R at rear with stock ARB at front
unfortunately not.

I tested the rear H&R by my own (fitting is much easier, so I did it first).
Cornering was really funny but little bit dangerous. I wouldn't track on the Ring
with this very ''lively'' setup.

If you fit a stiffer bar at the rear only then take care your rear axle is supplied
with some more 'toe in' and never with 'toe out' !!!

Where did you get these? Could you please tell me the figures for 26/22?

I mailed to H&R. Calculating the 26 mm will be no bigger problem if you have the
data for another diameter.

26 mm is around 70 % of the stiffness of an 28 mm bar (both solid).

I'm using BSH 27mm on the rear and H&R 26mm in front, both of them set on soft. Thicker rear bar will help you rotate the back on very tight corners but on tracks like Nring I think thicker front (like most manufacturers kits are) is safer at high speed corners !

  I fully agree.

I have got H&R 28mm Front - 24mm Rear, both set on Hard at the Ring Track and soft on road.

Oh, that's too much toil for me, Laurent. 
Winter: soft; summer: hard. Almost every weekend there's a slalom.

....And even more too much toil for me. Set and leave them 365 days a year 

[laurent.d]

I made it too short to be right.

I meant that hard suits track use when soft suits road use but as I'm lazy too, I end up in winter on ''soft'' as I don't go to the Ring and in summer on ''hard'' as I do.
