Hi
Currently converting my suspension to Koni sports (on soft setting). As I am taking the struts off and putting back I want to make sure the camber is set to standard. Does anyone know what the setting is for the front? It's a cab so I'm not interested in increasing camber.

Looking at the figures below it reads to me that it should be 0 degrees (neutral) with a tolerance of + or - 10minutes. Is that correct?

From 1990 onwards
Front 0' +/-10', max difference l to r 20'
Rear -45 +/-20', max difference l to r 30'

Cheers
 
It will depend upon the age of the car as they changed the settings over the life of the model.

The general advice is to find the year with the most aggressive settings and match those. For the coupe that was 1989, but I don't know what it would be for the cab.

Its a 1990 S2 so these are the figures for it, but I need it translating a bit. As its a cab I'm not interested in an 'aggressive' set up. Just want it as standard
 
Your understanding of the figures is correct, although the neutral layout of the 944 means it is quite sensitive to geo changes. A good geo can make a world of difference and it's worth getting it right. From those figures, I'd be asking the spanner chap to aim for the -10deg end of the tolerance.

Hmmm. Geo setup is one of the very few things that I'd be happy to pay someone else to do. I've played around with camber and tracking gauges on cars before and never managed to get it right, with the most common result being very aggressive tyre wear. If you can DIY with success then I doff my cap to you, sir!

Camber is fairly easy to get close enough Oli with a 30 quid caster/camber gauge. For balanced handling the easy answer is -1 degree more than whatever the rear is set to, for a pure road car anything around -1 degree or less is highly unlikely to result in any unusual tyre wear. The really tricky bit is to get the toe bang on not just front but also rear and by using a proper 4-wheel alignment rig one can check for thrust angle as any thrust angle will completely mess up whatever the toe angles are set to on each axle. The factory geometry in this area will be around -10 to -20 minutes in each side on the back and close to 0 on the front or just -ve or +ve each side of zero by a few minutes or so. Currently my race car is setup thus and I really love its smooth handling and easily exploitable limits, NineX gave me a base setup (including all the corner weighting etc.) that was identical to what they did for Ben Demetriou when they run him in the club championship and he won class 1 all those years back now in the 968. All I have done from their base setup is add 2 clicks of rear damper bump and take 5 clicks of rear damper rebound out resulting in me finally after all those years finding the perfectly balanced setup. And do you know what the amazing thing is? If one looks at the factory road car figures it is exactly the same geo just lower and with more camber. Porsche got the basics right from the start.

Very interesting cheers. Do you know what standard setting is for the front?
