What Suspesion Upgrades...?

[Ex Skyline]

Like it say's on the tin. I am taking the Turbo back to JMG next week to get the KW V3 suspension fitted and the geometry set up before we head for the Nurburgring in the middle of May [8D]. I know that this has probably been mentioned on here dozens of times before but, what else should I have done to compliment the new shock's? I was thinking about new castor mounts and uprated anti-roll bars front and rear with Powerflex poly bushes all round but, I seem to remember that someone on here said fronts and not rears or, was it rears and not fronts?? I need a bit of guidance from someone with a lot more knowledge of suspension set up's than me [8|]. I know 5od all about this subject and would like to get my head round the options before I take the car to Jon's garage. Any advice would be greatly appreciated chaps []. Many thanks in advance.
Pete.

Pedro, if youre going for delrin bushes all around then Id save a bit of money on the 968 caster mounts and fit delrin bushes into the old housings.

968 M030 anti roll bars would be nice but theyre not really available to buy new. Porsche has remade them after a period of unavvailability, but I have heard that theyre over-priced and lacking in quality. Id also ask Jon about the bushes beyond what youll see in a Powerflex leaflet, which make a massive difference on an old car. Im struggling ro remember what theyre called (on the spring plate etc), but no doubt someone will know and post. Theyre probably going to be expensive and come from America, but nothing to worry a man of your means! )

Hi Pete, i've got KW3 set up on my S2 it was put on by the PO. He assured me it was fully set-up.

Now quickly get excuses in...

when we bought the thing we only had about 10 days to to turn a road car into something that Brands Hatch scruitineering would pass, so we didn't give it much thought.

Seats, harnesses, fire plumbing, electric cut-off plastic windows etc. took priority.

Now over the winter I've had a more serious look mainly because I watched a video taken from a competitors car, showing me going round Donnington, from quite up-close-and-personal (We even swapped a bit of paint to show it was the real thing).

It was quite obvious that the rear end of the car was not secure!

Anyway the point is KW3's are fine but in order to ensure the rear seats properly you must re-index the torsion tube suspension. As if not the front end sits nice and tight, but the rear does not fully compress the helper springs. This is because unless the ride height has been lowered the coil-overs are not compress sufficently.

I can take photo's if you like.

Delrin bushes are out of my price range mate []. Thank you for your suggestions guys. Gonna chat this over with Jon but i'm thinking along the lines of Porsche Motorsport bushes (full set), and 968 MO 30 anti-roll bars and 968 castor mounts. Having new beams as well. These will be striped down and powder coated prior to being re-built on a bench and then fitted to the car [8D]. I must admit to getting rather excited about this little project [][8D].

Your going to love it Pete, sounds like a good list of parts, although I've never heard of the motorsport bushes. Is this going to be a Nurburgring hoon machine?

Substitute Delrin for polyurathene in my post then: same still applies.

Last weekend I had a ride in probably the best handling 944 ever.
KW V3, Uniball rear axle with Delring bushings, road tyres, set extremely low... the driver was pushing it beyond 90mph in corners I wouldn't dare going half as fast with mine, tyres weren't even squealing... That was insane, my stomach moving around about the same as when on an Airbus taking off...

I agree. Suspension for a car used on the road and that of a race car are completely different animals. If you take all give out of the suspension camber changes and pebbles will have you fighting to stop the car throwing you in the nearest ditch - or into the path of oncoming traffic.

If you got 26.8 mm front roll bar, I would get the stiffen triangle bracket 4 the drop links brackets off eBay. The rear you could get rise bushed drop link with the ability 2 Prerension the rear roll bar. Will be easyer then finding the 30 mm roll bars. Jon will prob set your car up slightly soft and prevent roll via roll bars 4 more grip.

Full poly bushes wishbone and torsion carriers will sharping up the streeing as well, Iv got front wishone and rear torsion carriers with poly bushes removed from my S after 2000 mile due 2 braking the car. Would like 2 put on turbo when funds allow but that will be awhile.

Pm if your Intersted

Get a front spliter as well, so u look mean

Have you met our Pete???? [][][][]





Sorry Pete, couldn't resist....I'll get my coat

 

[Copperman05]

John's right, if its mainly a road going car having it setup so its great on the Nurburgring or a track is going to make it pretty rough 99% of the time when your on UK roads, especially our B roads (where most fun can be had), if its a dedicated track car thats different but there is some truth in James May's assumption that the Nurburgring (setup) ruins road cars. A compromise between the two is what i would suggest.

[944 man]

I disagree that bushes have to give to make a car drivable. The compliance needs to be in the suspension units and if harder bushes make the car twitch, I would suggest that it is actually the dampers or their settings which are too firm.

Harder bushes will lead to a substantial increase in noise, vibration and harshness, though.

 

[Copperman05]

I dont disagree with anything you say Simon, I just think that many people when looking at new suspension and how they will set it up overall can tend to go to far to a track bias, compromising how the car feels when on the road.

944 man (sorry, I don't know your name), I totally agree with what you said in your last post all the way [8D]. Thank you all very much for all your useful comments chaps, they have all been filed away for future reference []. Andy Watson...what are you trying to say......[][],PMSL []. I do love a dry sense of humour!

 

[Ex Skyline]

Sorry Edd, wasn't ignoring you mate []. First and foremost the Turbo is going to be a fast road car. However, I usually try to get to the Nurburgring four or five times a year. One of those is just to spectate at the 24hr rennen(but I still drive there and back), the other times I spend two or three days ragging whatever car I have at the time to within an inch of its life! The last three seasons I have bought a Ring pass which, gives you unlimited laps otherwise it can work out very expensive on the day at 25 Euros a lap![]! Jon seems to think he can set my car up to give a balls out ride at the "Ring" (think" sticking like 5hit to a blanket")(sorry swear word police)but still handle superbly on the road. I am, however, aware that sacrifices may have to be made. I'm going to have some fun with this one though, that's for sure [8D]. I think i'm going to keep it as my little boy loves it [].

 

[944 man]

£fiver a lap the first time I went Pedro! DM12, from memory.

 

[Ex Skyline]

Those were the days eh ...Simon []

 

[edh]

Well you don't want it too firm at the nurburgring as some of those braking areas are very bumpy.

I'd leave it in jon's hands and do what he says as far as arb's and bushes....

btw - hope you're insured...

 

[Hilux]

what else should I have done to compliment the new shock's?

Re-index the torsion bars (if you havent already)

968 castor mounts

Weltmeister adjustable ARB`s - sensational alongside KWV3

What was the road noise and vibration like? So uniballs on the trailing arm inner joint, anywhere else? What about the front end?
