Whiteline Rear ARB fitted

i think i'll stick with the jabba one,in 10 years of modding cars i have found if you buy cheap,you generally buy twice.

Whilst 99% of the time i'd say you were totally right (You do get what you pay for) In this case we're talking about a Bar with a couple of bushes (not exactly complicated engineering to produce) and Whiteline (a HUGELY successful and well recognised Suspension specialised) vs JabbaSport (a well estabished VAG Tuner, but hardly suspension guru's)

All im saying is that it won't be an inferior product (from a fit / form / function point of view) and as previously mentioned by someone else, I bet the average Joe Bloggs wouldnt tell the difference between the 2 bars. So would it be worth the extra £100 to them??? (Assuming that the Jabba bar is indeed suprior which is still yet to be confirmed).

Anyhow, I look forward to my full DRY (hopefully) first drive tomorrow

[oilburninnut]

and as has also been said some can:rofl:

hey i'm not knocking it and it would have to be tested along side a jabba item,as has been said whiteline are a very reputable cmpany with a very good rep,in fact if i remember right my scoob had all whiteline gear on and it was very good:thumbup:

[Snoopie]

LOL Snoopie... i think Badger bill has a teeeny weeny bit more experience than you in this field.

Stop thinking too much. You don't want to turn into a complete ******.

[VrsMad]

I agree, hard to tell which is better without testing, trying to compare bar diameters, mounting points when the bars are not comparable won't shed any more light on the matter.

I suspect that it would be softer than the Jabba as it is design for the 9N Polo which most models have a softer front ARB than the VRS which has an uprated front ARB. No doubt whiteline would have taken this into account and tried to make it so the application is not too oversteery

Alot of carp has been talked about the the adjustability, which I think is a good idea, if you change other components you can change it to suite.

I'd be up for a group buy.

[vrshicksy]

After reading through this thread I have come to the conclusion that I know diddly squat about how cars work and generally go on the consensus of others on what to buy, however there is controversy in the camp over this product!

I generally drive my vRS on the motorway for work and then a series of roundabouts getting into town, and some country lanes for some fun, have never taken it to a track (although keep toying with the idea) and so think that for saving £100 (which don't forget is still £100 which ever way you look at it) then the whiteline RARB is the way forward for me. The likes of Badger Bill and the other regular track users / good drivers then probably the Jabba is for them!

That's my two pennies thrown in, feel free to shout abuse at me!!!!

I took my Jabba bar off last weekend, and doubt I'll fit it back on :eek: ...hows that for controversial

Do you care to expand on this?

I must say the Jabba ARB is good, but you have to know what you are doing when you push it hard and it lets go.

In the wet if pushed hard (rarely as its for nutters and BMW's in car parks!) the back end just slides, but a bit of the right foot puts it back in line.

First time I took it out I was like 'wow' and now it still catches me out!

I'm sure the whiteline one is just as good as the Jabba one - a solid bar that stops roll and reduces understeer, simple, all it has extra are adjusters and a different way of fixing to the axle.

[Chrispy]

The Whiteline one is 3mm thinner though, although the nature of the steel used in manufacture is unknown and so it may be just as stiff....

Bear in mind there are 2 ways to adjust the bar...the Whiteline one comes with holes at the end for the damper mounting points, but also it matters as to where you put the mounting brackets on the twist beam too. Further apart makes it stiffer and also the opposite applies....closer together making it less stiff.

Not sure about that. The bar is free to rotate within the brackets, so the twisting action is along its whole length of the ARB regardless of where the brackets are.

Yes, the bar can rotate in the brackets BUT it's also attached at the other end - think about it. If one end of the ARB was disconnected then yes, it wouldn't matter where the brackets were attached, but as it's bolted on at both ends then the position of the brackets will matter.

One end goes down, the other goes up - that's what happens when you corner. The ARB resists that motion thus resisting the rolling of the car. If the brackets are closer together then more leverage is placed on the bar allowing it to twist more and allowing more roll. Same goes vice versa.

[Chrispy]

Hmm.....although.....I've been thinking.....perhaps the bracket mounting position doesn't have an effect beyond a certain point. Can't find anything on t'internet to confirm.....

I suppose I better.

Insurance, saving money and warranty are some reasons. However, whilst I found the bar great for smooth surfaces, fast corners, roundabouts and I imagine is it a necessity for track use. I feel that on bumpy and uneven roads it is just too stiff, it unsettles the back of the vehicle and makes it skittish. I'm currently running completely standard suspension, and believe that the standard dampers are not helping, I've thought about fitting some FSD but this then brings me back to my first point.

I don't know which is the lesser of the two evils, unsettled handling on poor roads, or the unnervey (sp?) experience of feeling the car roll on faster smooth corners. At the moment I have chosen option 2

[Chrispy]

Sod it, I'm buying a Whiteline. I NEED one of these things. The car simply cannot handle well enough for my liking. After being in one with a Jabba fitted it's made me all the more keen.

Good man

you are right about the spacing. its not just twisting that affects the bar performance it can also bend Its similar to lateral torsional buckling and the p delta effect. Like if you load a cantilever it will deflect downwards but it will also try to move sideways. the same theory can be applied to the bar, its trying to appose twisting but to do this it also has to resist a bending moment.

I have tryed this and can say moving the brakets closer together does make the car less rigid. It you read jabba instructions it says that the brakets must be an equal distance from either end of the bar. if the theory of the bar only has to resist twisting were true this would not be needed

[Chrispy]

Ok, just been on the phone to Direct Line. Added my Cupra bushes (zero cost to add them even though the last time I spoke to someone they said it would affect my premium.....) and also got the RARB added. It comes under the category of "Uprated Suspension" and as such they're charging me an extra £79.80 over the remaining 6 months of my policy.

All in all I'm pretty pleased.....just gotta get the RARB fitted now.

[Chrispy]

Ordered. :D

Want it....want it now......

Okay, I accept that the bar can flex. However surely it can only flex vertically from the bracket to the end of the 'bar' (i.e. the point where the 90' curve is in it) if we assume that the poly. mounts are rigid.

So for example if the brackets are 150mm from the bars 90' curve, the ARB can flex vertically in than 150mm, equally the same for any measurement. However, since the ARB is only 10mm or so from the axle beam, surely it will make contact with the beam before any noticeable difference is felt? Yes / No?

Chris: glad you got it sorted. Let us know how you get on!

[Decron]

I have just ordered one for the Roomster.

Hope it fits.....

[Chrispy]

Is the Roomster baed on the 9N chassis?

No, the rear is Golf 4 meaning the G4/octy one should fit hopefully. With the Roomy it's not about getting better handling (Although thats a + point ), it's more about just reducing the body roll.

It's not as bad as most people would think (Standard Roomy handles at least as well as a standard VRS) but if I can get rid of some of the roll for £130 then game on!

If it doesn't fit (The set up looks and mesures the same) then all is not lost as I should be able to get rid quite easily. Nothing ventured, nothing gained The Jabba bar was brilliant on my VRS, if this is half a good i will be happy.

[Chrispy]

It's arrived....woohoo!

Shall be fitting tomorrow. Then I think me and Skudmissile are gonna have to do a proper comparison between my Whiteline and his Jabba for the benefit of all you guys.
