I'm in the same camp as
@BognorMotors here. I get where
@CRS Performance is coming from but certainly I found with standard T32 suspension, the under rating of the shocks is very slight, with respect to controlling the torsion of the ARB. This was a post I added in another thread sometime ago. LWB shuttle conversion to a camper with a pop top roof....
Had the H&R ARBs on for three weeks now and had a chance to drive the van over various types of road.
Decided to fit them from a comfort point of view to reduce the tip you out your seat, 'standby to go about' lurch on the bends. Have to say they've come up trumps. On what's pretty much a permanently half loaded van, I would go so far as to say they've significantly reduced body roll with my standard T32 suspension. Generally, a much taughter feeling of turn in and overall a more enjoyable drive.
Can't comment on understeer/oversteer balance, as I've yet to make that kind of progress since they've been fitted. Well, that combined with valuing what's left of my current tyres and preservation of the on board crockery.
Two things I've also noticed. Firstly over uneven surfaces, the movement is a bit more up and down as opposed to side to side. This in my view is a good thing in terms of comfort. To be expected, as stiffer ARBs reduce the amount of independence the suspension has across each pair of wheels.
However, and its only a small thing that you have to tune into to notice, and its only with fine irregularities in the road surface. But there is what I would call a low amplitude, higher frequency resonance, through the steering wheel. It maybe due to the harder bushes. Or maybe the standard dampers being slightly underrated to deal with the energy stored, with the increased torsional rigidity of the roll bar. Especially when its added to the existing spring rate. Perhaps a little too much combined twang in the set up without uprating the shocks. It's the balance of compromises thing again.
Although, VW recommend 56 psi in the fronts with my Devonports, dropping the front tyre pressure SLIGHTLY, helps take this resonance out the steering. Although I'm not condoning such behaviour, before anyone kicks off. Just saying. I've played about with the pressure, purely in the name of donkey science and curiosity.
So would I fit them again? Well, wish I'd fitted them sooner.....
.....One day I'll probably end up with the Koni active dampers too, but the H&R ARB upgrade in standard suspension is well worth it. Atleast with a T32 standard set up.
