S2 anti-roll bars upgrade

I am looking to upgrade the ARBs (front and back) in my S2 and wonder what are the options available.

Are the ARBs in the 220 bhp turbo the same as the S2s?
Will the later 951 ARBs fit the S2 and will I need new drop links and brushes?
Are there any other better after marker ARBs available? I saw some after markets ones asking for £600+ which doesn't seem right to me cos they are just bended metal bars right?

Please advice.
 
Most people tend to fit the ARB's from the 968 M030 option which are 30mm fixed at the front and 19mm adjustable at the rear. They fit into your standard mounts and droplinks and all you need to change are the bushes. Exeter OPC are very familiar with what you need and normally supply the lot for around £300 delivered. The rear bar has three settings so you have a bit of adjustability to play around with until you're happy.

Weltmeister in the US make a completely multi-adjustable version which is considerably stiffer (and heavier apparently). Promax stock them for £640 http://www.promaxmotorsport.com/welt_sway_bars.htm
 
Big thumbs up for the 968 M030 ones from me, the adjustability of the rear is quite useful too. There maybe another alternative too, a guy called Flash on http://www.968forums.com/ (you'll have to register, but it's free) has produced some arb's that are supposed to be half way between the M030 and the Weltmeisters in terms of stiffness, but cheaper and lighter than the latter. I can't recall if they've been released or even sold out and I can't seem to log in from here, but it might be worth a look.
 
The 951 arb's came in two sizes, the thicker ones being used on the later cars. I had some of these and they were an awful lot softer than my current ones (probably a good compromise for road only driving however). I'm not sure what size the S2 had as standard, possibly the same as the earlier 951 parts, but that's only a guess. So I'm not sure if it would be much of an upgrade. There shouldn't be any problems with fitment.

Does anybody on here know what size an S2 has as standard (mine is a late car if that changes things)?

I was just about to order some bushes from Bert but realise I don't know the diameter of my anti-roll bar - the car is in the bodyshop so I can't nip out and measure it.

Ask the body shop to measure it??

I thought the answer might be common knowledge on here.

To be honest I'm keeping my head down a bit with the bodyshop, I took the car back to them for a few final finishing touches but seem to have got them doing a long list of things that are nothing to do with them for free. They really are excellent and only too happy to help.
 
Matt, unless someone posts the answer ring me later and I will tell you, haven't got the info to hand.

Which bushes is it you need. I have loads of standard bar bushes in alsorts of conditions. I am sure I will
have good ones of the ones you need.

I'd still give Bert a call if I were you, I'm sure he'll know off the top of his head.
 
Peter,

Where is your verdict on the 968 M030 ARBs? Are they OK for normal road driving?
Did you have the stock arb brushes or some poly ones?
 
S2's didn't have a standard size of ARB - it varied from car to car.

You need to measure them with a vernier (or micrometer.)

M030 bars have very little effect on the "harshness" of the driving. They just reduce the roll somewhat....
THE best option / upgrade on the steep ladder of modding......[In my opinion.]....[:D][:D][:D]. Especialy when combined with fresh struts / shocks....

Ive fitted them to ALL the 944,s + 968,s ive owned....With both standard bushes +/or polys...

If its mainly the road use , then stick to standard bushes....

MATT
Your car seems to be in the body shop a lot lately.??
If they are good, i might be needing there services sometime....
Are you coming to Donnington on Sunday, to sample the S2 / 968 "shootout"..????

There was a noticeable degradation in ride (I was already on much stiffer springs and dampers too) but it was so much flatter through corners it was well worth it in my mind. I suppose it depends how hard you drive the car as to whether you're willing to put up with this compromise. I guess some people would say that's not what having a cab is all about, but certainly based on Flash's 968 cab that I mentioned above it seems they respond just as well as the coupe to this kind of thing. If you grin everytime you see a roundabout on the horizon then I'd guess it's for you [:D]

I've just recently gone to polybushes, but this was with lots of other changes so I cannot comment on what this did on its own. I would definately get some KLA arb braces (from ESS) which triangluate the droplink and are really important when increasing the stiffness of the arb's.

I stand corrected on the size of S2 arb's I didn't realise Porsche had changed the spec over the years. I do talk a lot of twaddle at times :ROFLMAO:

Dave,

It was in the shop longer than I expected (6 weeks rather than 2 as with each job started more was found) and now it's just gone back in for a few finishing touches as the paint has set etc.

It's in at Surface & Design (ex-TVR guys, just off Bristol Avenue, 01253595800, http://www.surfaceanddesign.com/) and you're welcome to have a look at the work done on mine to get an idea about the quality of the job. They're a really good bunch, true enthusiasts and have completed some very impressive projects to date.

Very tempted by Donnington on Sunday (car should be back tomorrow). The only thing putting me off is that I have slightly too little fluid in my transmission at the moment - 2 quarts rather than 2 litres so circa 0.1 litres short - so I'm a bit wary about a longish drive.

I think that they simply bolted on whatever they had to hand at the time ...

Perhaps, but you also talk a lot of sense far more of the time, so I wouldn't be too hard on yourself!

Thanks for that, I just had a look on 944Online (because they have pretty pictures) and realise just how many sizes there are now!
