I think I know the answer to this already but might as well ask....
If I fit an uprated front ARB do I "need" to fit an uprated rear ARB?
Obviously it would be best to but is there liable to be any negative effect of not doing so?
cheers
Paul

If anything, you want a rear ARB by itself rather than a front ARB.
The front ARB stifffens the front and, by itself, will make the car understeer more. The rear will, by itslef, make the car oversteer more.
Now given that the coop is a very front heavy car and suffers quite a bit from understeer, putting on a rear ARB by itself will improve handling quite a bit. Putting on a front ARB by itself would, most likely, be detrimental to handling of the car.

my own personal experience (includes Spa) is that arb's are a great mod. i first added a "Nigel" lower brace and felt a little bit of improvement. i then added a whiteline arb which made it feel much more planted and flat, and i then added a dedra front arb - this combination ON MY CAR seems to work extremely well at eliminating any roll and also reduces lots of the usual understeer

yeah that's the one - you can get a 22mm one that pretty much fits straight on, or a 24mm one which apparently gives a fraction more stability but is a pain to fit. you have to fabricate new brackets for them. i'm VERY happy with my 22mm whiteline oh, i paid about £125 i think

cheers Proccy, I'm picking up Nigel's old dedra front ARB in a couple of weeks so just wanted to check if I needed the rear with it. Looks like I know now, ah well whats another £125 or so (sigh) might give me the motivation to fit the solid rear bushes that've been sitting in the garage for the last year or so

Just so you know, dont go to the garage with a full petrol tank. Either the tank needs to be removed completely or sorta moved out of the way a bit to fit the rear ARB. So you want as little fuel in the car as possible.

So a good starting point is just the rear ARB?
Not just the front, either both, or if its going be just one, then the rear?
Cheers.

Rears seem the ones to go for. That is the avenue I will be exploring. Paul

another thing to strongly consider for all you suspension modders, is the sub-frame seam-welding that Joe at Countrycruising does. this further stiffens the front end aiding both turn-in and flatter cornering. i've not had it sone but i've heard it makes a significant difference

I would recommend only fitting the rear bar if your just wanting to do the one bar or fitting the Eibach pair of anti-roll bars as these really do flatten her out through the bends.

cheers jmbo - i stand corrected but, as i said, i haven't had it done so was just going from what i thought i heard from Joe and Patch.
i can certainly confirm the effects good arb's have and uprated polybushes/suspension bits

Agreed - fitting my Novitec 23mm rear ARB was by far the most effective handling mod I've ever done
However, due to my lack of understanding of chassis dynamics at the time, I had fitted an uprated front ARB in isolation, which mucked up the turn-in. When I uprated the rear as well, the difference was amazing
Just for reference, for the new car, I've decided to transfer the uprated rear ARB, but I'm staying standard at the front be interested in how you compare the standard front to your current set-up, after you've done a few miles.

I regularly manage to keep up with 'good' handling cars on the track (e.g. Elises) ... although driver confidence has a lot to do with that, as well
