Anti Rollbar feedback
 

Hi All,

I have a newage STI and was wondering what ARB everyone uses?

I understand a 24mm adjustable would be really stiff whereas the 22mm has a more comfortable feel to it. This will compliment a full geometry fast road setup planned soon but know the ARB won't affect this.

What are you guys using out there and what is experience between the two sizes?

p.s. I have an 05 blobeye which has the rear metal rods not the C-shaped drop links.

Happy for hawkeyes, classics, bugeye owners to also comment on theirs.

Many thanks,

Chet

Hi Chet.

I've tried quite a few combinations on classics and New Age.

V4 STi Wagon for road/daily use I ran a rear 22mm on middle setting. This firmed things up overall nicely. No understeer, mild lift-off rotation

2004 JDM 370/360 twin scroll weekender I settled on front 23, rear 25. Neutral, not too firm

Current Type R weekender 23f/25r - suits the car very well

Current Bug STi Wagon, daily drive - 22F/24R. Car was fitted with a 22 rear adjustable, std front when I bought it. Also had rear pillow ball lateral links fitted which give alot of rotation. Have now fitted 22 adj front, running on soft setting, and tightened the rear up to full firm. Nice balance for daily and a bit of hooning. Less roll, tighter overall. Could easilly go for a 24 adj rear though :D and tighten the front to full firm. This would give the full range of adjustability, and if the 22 hadn't been fitted already, I would go this way

All depends on what you're after. You could go even more on yours. Say a 24 front and rear...

I fitted a rear Whiteline 24mm adjustable bar a few weeks back and it makes the car feel a lot different. Turn in is immediate and it,s easy to balance the car with the throttle. I have it on the middle setting but will try it on the hardest soon. There is no issue with comfort arb,s make no difference to me.
I also have BC coilovers, Perrin PSRS/ALK and Whiteline strut braces and together with a good geometry set up the car handles really well.

I borrow the thread since it is the same question :)
How about Whiteline 27mm both front and the back?
I stumble upon a great deal with a pair of brand new 27mm ARB, but only half the price.

27mm is too much.
On a newage approx front 22mm and rear 24mm is fine. But go for adjustable type.

Cheers guys. Funny thing is I got a geo done by Greenwood racing in surrey as well as fitting a Whiteline ALK which has made the car feel amazing.

My ARB's are standard but I'll probably run it as it is for now but more likely to upgrade the rear to an adjustable whiteline 22mm to stiffen it up alittle (not sure if I need to having done the recent mods) but reading around a rear ARB will make a difference and is an inexpensive mod to have.

Ricky, as part of MSOC which area to you live in

I live in Abbots Langley, Herts! ...its extended MSOC territory!

What mm is a standard STI ARB?

19mm

Nice... hope to see you at the next meet mate.

Thanks.

Does a few mm really make that much difference then?

With arb's, size very much does matter. For every 1mm increase in the bar's dia, torsional stiffness increases a huge amount. I haven't got the figure to hand, but It's almost exponential. You only have to adjust a front or rear arb setting and feel the massive difference to see this for yourself

I have 27 mm bar on the middle setting on my bug sti, I did have a front 22mm aswell on the soft setting, it could be my imagination but Im sure it handles better now with just the rear bar.

I found with both front and rear the car did turn quite well, but I needed to be quite aggressive, with just the rear im finding I can carry a bit more speed in to a bend, I can get on the power sooner and dont need to be as aggressive with the steering, its like the car pivots on the spot and just points where I want it to.

It is a tad twichy though, but I have done absolutley zero track driving, so maybe my observations are not valid for the track.

Just wondering if its possible that rear bar only suits my driving style (Coilovers are totally knackered though, Kw going on at end of month fingers crossed) or if my limited driving expereince (never been on track) means I cant fully appreciate the benefits of both arbs?

He wont be able to make it as he is double booked:lol1::lol1:
