Have booked in with Matt Bentley to fit Quantum Zeros in place of my Gaz Nickels.  Nothing wrong with the Nickels, but bits of reading say the quantums should be a much better damper, if only for the fact that they cost alot more.

 

Matt has suggested an uprated ARB at the same time.  Just wondering what people's thoughts were in terms of how much difference this is likely to make? 

 

Are we talking a tangible difference as it's not a cheap part, or are we well in to the area of diminishing returns?

being blunt, it's a fundamental, and yes, you can't not tell the difference.

, if only for the fact that they cost alot more.

Based on that alone, I'd keep quiet in technical discussions from now on :lol:

Is that comment to do with cost being a poor yard stick to compare dampers?

Forgive my ignorance but what is the benefit of the uprated ARB?

 

Is it worthwhile on a car with standard suspension setup?

It should reduce bodyroll without having to run harsh dampers or stiff springs.  The bonus being that it doesn't affect ride quality.

 

If that is the case, why not fit a 1" bar from the factory?  The fact that it wasn't means a compromise was made somewhere?  Was that based on cost or something else?

The way I understand it, is because the average driver needs a bit of body roll to help them judge the limits or the car before it starts to slide.

As most of us are into fast road and track setups, we understand that less roll means improved cornering and direction changing, but also makes it harder to judge the limits.

My spin at Rockingham taught me where that limit was in the wet, and how s**t I was at judging it. -_-

I have one fitted, it makes a decent difference, sharper turn in, and much less body roll. I was very surprised with how little it affected the ride on standard NA suspension. I've fitted exige suspension as well, and I found it was giving me too much understeer, so I put it to the least aggressive setting (both sides closest to the front of the car).

 

Are we talking a tangible difference as it's not a cheap part, or are we well in to the area of diminishing returns?

 

You're probably at the start of the road of diminishing returns, but not too far along it :D

Its as good a mod as harnesses or suspension upgrade IMO.

Yes. Spunk more money, but this is one of the more noticeable driving mods.

Disclaimer: I don't know anything about suspension setup. But, I thought increasing the front arb stiffness and not increasing rear spring rate would change the balance towards more understeer? Could someone explain why increasing the front arb is a good thing without matching it with other changes?

Ehm, you for that sure mean you have it set it to the least aggressive setting, being the farthest point from the front of the car... (longest leverage setting) :wacko:

There should be a balance between front and rear roll. With no ARB and just the springs, roll will most likely differ front/rear and usually quite a lot. With the ARB you can balance that. So yes, in theory when you change springs, you should also change the ARB. The question is what to change it to. Having said that, the standard ARB doesn't do a lot, the rating is about equivalent to 50 lbs/inch. Which is probably OK for the standard springs. Same ARB, same inside and outside diameter I mean, but with a series of holes and using the hole with the least leverage (closest to the bar), it's about 90 lbs/inch. The 1" bar is considerably more going from over 150 at the lowest setting to over 250 lbs/inch at the highest. Going from the OEM bar to the 1" bar, you will for sure notice the difference. Even on the lowest setting.
