Would these make much difference with coilover fitted??

I want to get the suspension sorted so it handle good, i guess this would help on my quest??

Topper, I feel that you are basing your decision on the ARBs solely on opinion of one person. Please remember that that same person has a tendancy to believe he is the total expert in everything he says. Although I respect and value SOME of the things he says, quite a lot is opinion and not actually fact. I probably come across like this sometimes too. However, I won't say something unless I know the subject, and I'm the first person to apologise if I'm wrong.

I would be more inclined to go on what everyone else is saying rather than just one person. It would be interesting to here what the Aussies and Kiwis run, as they have much worse roads than we do.

I hear what your saying mate, but the more i think about it the less a can justify them.

I dont get alot of bodyroll as is, and although its only the theory of one person i can totally see where it comes from.

I like to know what the car is doing and i think i get to know how close to the limit i am by the angle of the body, although i only have a small amount, it is an amount i would be less confident without.

All in all i'm happy with the ride and amount of bodyroll so dont want to change it :thumbs: ATM, this may change in the future, but for now i am happy, and i dont want to spend ?200 sheets if this will upset the car, or my confidence.

Ofcourse i am willing to listen to others theories, so if you have any experiance of having coilovers, then fitting ARB's, please post your findings :wave:

You may find this Whiteline FAQ on swaybays quite interesting. I've just sent an email to them asking for their opinions on running them with coilovers. They have hands-on experience of S15s and their tech guy is a true suspension guru.

So to conclude a larger rear bar in the wet should leave the car balanced however it would be slightly disadvantaged due to the high stiffness
The rest of there article didnt tell me much, it seems to all be geared for a track car, mine will do some trackdays, but mostly be on bumpy b-roads, i'm still confused/not convinced

That's why I've emailed them. I've asked for an unbiassed opinion on the setup with a link to this thread. I posted the link above more for an explaination of ARBs rather than answering your question. :)

I gathered that, and since there is a chance they may read this thread - It is an excellent write up :D :wave: (i'm not joking)

I have done some more searching, and i think that where the track is concerned, ARB's are a good upgrade, however, this is not the case in either wet weather, or bumpy/uneven surfaces.

In my case, i drive alot of B-Roads (and mostly wet B-roads at that), as i live quite rural and have no choice, but they are great fun. I have read that upgrading the ARB's would not be a good idea (in my situation) for roads with dips etc, as if one wheel hits a dip, the opposite wheel will feel the effects and make the car unseated, which i take to mean a form of being unstable.

Been a bit busy this morning and completely forgot to mention this. :rolleyes:

Got a quite reply back from Whiteline, as usual :)

Whiteline said:
Thank you for your email.

Whiteline's philosophy on suspension design and tuning is quite simple,
we look at suspension as a whole integrated system. This however is a
very complex proposition, as there are a many physical parts that have
multiple effects which interrelate with other parts, so the number of
possible combinations is almost infinite. With that in mind we design
and tune individual products in such a way that they offer a performance
improvement on their own. Equally importantly, each individual part must
integrate well with other related components, as only then maximum
performance gains can be achieved.

In other words, Whiteline is not solely spring manufacturer, or shock
manufacturer, or swaybar .... etc.. as that would restrict us from doing
what we do, and that is providing complete, tuned and matched, tested
and proven performance suspension solutions.

Our design and tuning processes require of us to break down each
mechanical suspension part to work out and calculate its function and
effect on suspension characteristics on that particular car.
During testing, we need to validate the modification done. We only
release parts that pass our tests and requirements.

To answer your specific question, we are yet to find a reason not to
combine uprated swaybars with coil-over if the components are
appropriately designed and tuned. This is due to the fact that each and
every suspension component such as swaybars, springs and shocks perform
different functions, and quite often this is interrelated. A well tuned
combination of components is the only way to extract the maximum
performance.



Taking our above analogy further, the following may better illustrate
our point. The numbers are arbitrary.

Option 1)
standard suspension:
springs: 3kg/mm front, 2.5kg/mm rear
Swaybars: 22mm front, 20mm rear
Tyres: high performance street tyres

Option 2)
uprated spring and shocks (coil-over) only:
Springs: 8kg/mm front, 6kg/mm rear
Swaybars: 22mm front, 20mm rear
Tyres: R-compound semi-slick

Option 3)
Tuned package using uprated springs, shocks and swaybars:
Springs: 6kg/mm front, 4.5kg/mm rear
Swaybars: 24mm front, 22mm rear
Tyre: R-compound semi-slick

I think it is clear of which would be the ultimate option/package.


It is also important to note, that the suspension components and their
tune, MUST only be appropriately chosen after and based on the tyre
choice and type of driving the car is being set-up for.


For more information, please feel free to have a look at the following
links, and do not hesitate to contact us if you have any questions.

Think that basically saying that you can't make a sweeping judgement about coilovers and uprated swaybars. Its dependent on the overall setup of the car.

Agreed, but it also says nothing about fitting uprated ARB's and running on uneven roads.

I totally see the arguement, ARB's are good and they do something different etc, but for my particular application, i'm not sure if they would help or hinder.......... think i need to dig further.

Cheers :thumbs:

On the road, the correct question is whether the car will be primarily used on relatively smooth or bumpy surfaces. A well located live axle will perform at least equal to if not superior than older designs of IRS systems on all but bumpy roads where greater independent compliance of most IRS systems will prevail. Bumps encountered by one wheel will not effect the other as much as with a live rear axle. A good IRS system will however offer suspension tuners the ability to change the rear wheel alignment setting, which is an advantage.
IRS stands for "independent rear suspension."
