For a MY03 STI.

I am not after 100% handling but just an improvement.
It the 22mm going to be an improvement over the OE one or should I go for the 24mm ? I am refering to the rear only.

Thanks Bob

.................also should I go for an adjustable one ?

So 22mm
24mm
22mm adj
24mm adj

IMHO:
24mm adjustable from Whiteline.

It has 3 settings which are very easy to move to suit.

If in doubt, use the middle of the 3 holes and the car will be nice.
Always take it easy after such mod, as the change of characteristics to the car can surprise at first.

I have a 24mm adjustable on a classic (with 22mm adj on the front) which IMO works very well for the road (soft setting on front, medium on rear), so I'd go for a 24mm for the newage.

Also for the small difference in price go adjustable, I'm sure I read on here the 24mm on its softest setting is the same as a 22mm non adjustable anyway

Guys, Bob here has an Newage STi, what works for a classic doesn't always work on an STi and unless you've actually tested the products in question you can't really make a recommendation.

Going by Whiteline's charts going from a 20mm rear bar to a 24mm will give an increase in roll stiffness of some 100% - that's a massive change and may not suit Bob's requirements.

But then what do I know, I'm still running the stock bars on my STi

I fitted a 24mm, (and ALK) which was 'alright' on track, but still understeered/slid on some corners with standard JDM Springs.

Then I cheated and had the remaining bits fitted for Full T25 suspension.
The trouble is, I have never been back on track. Always too busy...

No direspect to any other supplier, but Litchfield/Powerstation did a lot of R&D on the original Newages in 2003 and I would suggest at least phoning them for a chat.

Thanks for the input guys.
A chat with Powerstation me thinks.

Call them and get Curtis directly on the phone.

Let us know what feedback you get.
I have found on several Classics that the handling deteriorates noticably with stiff rear bars. Too much under steer. Currently I am very happy with a 20mm on an STi3 Wagon. Not relevant to a New Age but in this instance, stiffer is not always better so take care.

Thats interesting Harvey, I've found the stiffer the rear bar, the less understeer - if anything if the balance front to rear is too stiff towards the back, then the car tends to oversteer and get quite snappy.

I'm sure driving style is also a factor too

How you like the car is everything!

I have 22mm front and 24 (middle hole) rear and it is great.
The 3 other hillclimb cars in my class are exactly the same and each has a different make coil-over set-up.

I tried a 27mm front / 24 hard hole rear for a while (!) and although different, it wasn't too bad in the dry, but a shock in the wet with acute understeer.

I have recently fitted 22 mm adjustables to front and rear.

The front is run on the softest setting and the rear on the middle (started on the softest setting). The improvement in reducing body roll is perfect for all round driving without sacrificing good behaviours. The best benefit though is the improved turn in - you can really lean on it with that setting and is a marked improvement over std with correct geometry set up.

I think the 24mm, even in adjustable form, would have been too stiff for me at this stage at that alone would have been another 50% reduction is roll.

I opted for the Whiteline 22mm adj on my 05 STi to complement my Prodrive springs. Had to fit solid drop links as the bar moved from side-to-side with the ball joints and existing mounts. Whilst there was some improvement on the softest setting, I changed to the middle setting following the advice I received on this forum (thanks guys!). The improvement here was much more significant eliminating the understeer to such an extent that I ended up a bit wary about oversteer with my RE070's! After experimenting a bit I settled on 34psi front and 29 psi rear with my 235/45/17 PS2's. Can't help thinking that uprating the front bar a tad would also help, but I feel that the car still sits too high, not helped by the standard seats which are also quite high off the floorpan - possibly due to the seat height adjustment mechanicals

If you installed a good race seat on fixed position frame you will sit a full 50mm lower in the car. You cannot believe how better that drives.

i`ve just fitted an adj 25mm rear one on my newage sti and set on softest setting and its not as stiff as i thought it would be,seems to turn in realy nice and less understeer.just got the front one to fit now and see what its like then.

cusco kid

for normal road use the 22mm adjustable with mod/whiteline d/links will do if you want to track it go for 24mm or for real torsion the 27mm w/line is the dogs bo--ocks all adjustable i am setting up scoobies all the time go to whitline site and look at the torsion ratios for anti -roll bars dont just mod the rear then do the front for best results. by fitting the w/line rarb you will notice right away that the front end handling is transformed its sharper less under steer, although its advisable to fit a front anti-lift kit for ultimate results geo

Cusco echo's my thought
I'm surprised that many only change the rear

On many cars simply changing the rears leaves the cars unsettled, especially into high speed bends

Much better to increase the thickness of the front at the same time otherwise you'll see an enormous change in the handling characteristics that will catch you out closer to the limit....... fitting a 24mm and leaving the fronts can make the car 'snappy' on the limit and you may find yourself in some scary situations

I put a 22mm adjustable (Whiteline) rear bar on my 2002 Sti and it made oversteer a possibility if provoked, but massively reduced the understeer as the car cornered flatter.

Then fitted the front adjustable bar, and apart from being a jiggly over ridges (both on fully hard), just got even more front end grip, to the point where the rear just grips now....

P.S. ALK also calmed things down on cambered roundabouts !

Next up struts and springs, or coil-overs...... ARGH !

22mm front/24 rear on middle hole:

Have a few other tweeks as well mind, but the car corners flat.

After speaking with Powerstation I was advised to go for the 22mm adj front and rear or 24mm if tracking in mind.
All ordered up and should be delivered Monday.
