Does anyone have a recommendation for which specification / manufacturer of uprated anti roll bar to purchase? There seems to be a selection on the market ranging from �120 to �400.
eliseparts 3x stiffness adjustable for me.
same here.
Hanger111 for me
May seem expensive at first but this does include mountings and proper, adjustable rod end bearing drop links. Quality is second to none.
Thanks for the recommendations.
The Pilbeam kit looks superb and they have an excellent reputation but that’s a bit more than I want to pay.
Still not decided which to go for yet 
Er Hum…why do you need an uprated one ???
Just curious.
Fair question. I have to say that the standard bar with Ohlins is relatively very good, especially in wet conditions.
When pushing hard in the dry I’m getting too much roll, even with a hard compression setting on the dampers, resulting in the inside rear spinning up on the tighter corners. Fitting an LSD will assist but I feel it isn’t helping the root cause of too much roll.
Harder spring rates isn’t really an option for me as I compete on some undulating tarmac stages and I think that will destroy the stunningly good straight line handling.
Stiff damper settings won’t reduce the roll, just the roll rate.
The only way to reduce roll is using a stiffer arb or stiffer springs.
What bar do you currently have fitted, the std one or the Lotus adjustable one, if it’s only the std one then I’d say go for the motorsport one, i.e. not the stupidly stiff one from Eliseparts as you probabaly don’t have the spring rates to work well with that bar.
Nice piccy! It tells a thousand words! 
The 2.25 times EP bar is good value. Mine is on the mid setting and that is more than stiff enough… perhaps too much so as I get some understeer! (YUK!) 
Well I read all of this but just get confused… you need a stiff one but not to stiff… I am guessing there are downsides ie understeer or oversteer?
More to adjust means more for me to mess up, when I spoke to the ex Penske engineer at Nitron he pretty much said the std set up was more than good enough for my needs so I think I’ll leave well alone
Boothy, looks like mine is just too limp! 
Mark, yes I agree firming up the compression doesn’t fix the roll issue, just the roll rate. However it does make a significant difference to the handling by controlling speed of the weight transfer and maintaining traction.
Thanks for all the feedback. The best solution for me sounds like upgrading my standard one for a x2.25 adjustable one.

It does improve handling, balance and traction but only if you get the bump vrs rebound levels correct which some of the ‘fashionable settings’ don’t.
But it also effects things like steering feel, ride quality etc so it’s a definate trade off.
Too many times I hear people say that their car looks like it rolls too much in pictures so the whack the damping forces up as they think that will compensate, it won’t. Also roll is only bad if it leads to under/oversteer, if the car handles well and is nicely balanced, why does anyone need to reduce roll?
Similarly because a couple of vocal people have made statements about how you can’t run a stiff enough ARB people seem to head down that route because someone on a forum said so, and without knowing the spring set-up on the rest of the car that can be a mistake.
You need to get the roll stiffness balance right, it’s a fashionable trend at the moment to go for big spring differences between front and rear and what isn’t mentioned is that people then need to run a much stiffer ARB to compensate and then they will claim that the bar made a huge difference and everyone should buy one.
If you have relatively soft spring rates, i.e. 400/475lbs then fitting a 2.25x stiffer bar will have a much bigger effect on roll stiffness balance that fitting the same bar on a car with 550/750 springs.
So anyone looking at ARB’s need’s to look at the whole set-up otherwise they could end up screwing up the handling balance.

How would you judge the recommended Ohlin settings posted for various tracks? I find them a good benchmark although I tend to leave the ARB as I CBA but seriously finding a true balance is like doing bloody algebra�…its way way over my head and probably always will be. I don�t tend to stray and keep in mind which tracks are similar to each other if using them but always start on the softer lotus recommended track settings and return to them if I feel I�ve balls�d up. I see my car �roll too much� in pictures even at Spa with 2/2 all round but I�ve never thought it a problem, it just looks it I agree. I’m still learning and I only ask about these benchmark settings because I have no idea where they came from and it helps me keep life simple?
I went for the EP 2.25 bar in the end, seemed the best value. For what should be a realtively simple job it was a pain to fit, even though I already had the clam off. It would be slightly easier with the wishbone out and no Ohlins cans in the way. It needed a sawn off allen key and 1000 quarter turns.
Set it on max stiffness for the dry, good to see it’s now peeing down with rain! Only problem with this hole position is that the bar touches the underneath of the lower wishbone when in full droop, could do with some slightly longer linkages.
+1 Quality is good, and they are very nice people to deal with which always makes parting with cash that much easier!
Are there any of you guys left with standard springs / dampers / ride height on an S1 Exige? If so, have you messed around with the adjustable ARB? Any benefits / drawbacks from moving away from the middle position (oh err)?
Cheers,
Clive.
