adjusting anti roll bars
Discussion
Presume it is the same as a GT3 - fairly easy although you have to take the wheels off - both of them, so you need to lift 2 sides at a time.

Just be sure you know what you want to achieve with this, I have experimented a lot and wouldn't like have to done this at trackside as it can give unexpected results.

right, that's very usefull. i take it that you have the same settings either side (it wasn't clear whether you left one side on default and one side on softest).
i also assume the front and rear look the same, and that the softest settings are at the outside end?
also what would you have as a track set up? i think mike knivett had his softened by one holes at the rear and hardened by one hole at the front? is this right?
mike?
bueller?
anyone?

If the front bar has been be slacked and the rear tightened that will reduce understeer and promote more oversteer....
Be careful playing with the anti roll bars on their own as less front and more rear would normally mean that you'd need a bit more camber on the front as they will roll more and you need to keep the same footprint of rubber on the road.

Silly question but What are you trying to achieve?
A setting for one person may not be the setting for you! There's a lot that can be done with the nut behind the wheel before you need to start adjusting the car....
this is absolutely correct, as with all other comments in the post. i am merely looking to experiment with the car with various set ups that are easily adjustable.
the reality of the situation is that the nut behind the wheel needs some lessons.
i have been talking about this at lunch and lessons will start tomorrow with adjustments much later down the line when i actually know what the car is saying to me and i have better control of it.
thanks for the response though.
Basically (open to correction here) but the firmer the anti roll bar (closer hole to the bar) then the more you will be transfering spring pressure from the unladen (inside wheel) to the outside wheel which will have the effect of a stiffer spring on the outside wheel.
Generally stiffer bar at the back - more oversteer
Stiffer bar at the fron - more understeer
Generally stiffer bar at the back - more oversteer
Stiffer bar at the fron - more understeer
my was changed to hardest at the rear and softest at the front, was total crap in the wet as per my goodwood report, they have now reduced by one each end and am looking forward to seeing how it feels tomorrow at bedford, the guys from camtune adjusted it at goodwood, if u are as useless as me at mechanics dont try it if u have half a brain then didnt seem to difficult, are you there tomorrow?

Yes, to be clear, the bar can only move once both sides are undone, and they can onlt be set to the same settings.
Front and rear are the same except front has 5 settings and rear has 4.
The further you are from the bar then the softer it gets.

Not strictly the case. If you soften the bar at the back then that can induce body roll oversteer as the momentum of the car`s roll carries through and brings the back round.
It`s a complicated business this car set up thing !

Are you sure about this? One of mine came undone (GT3RS) and I replaced the nut without even jacking the car up. Looks to me like you could adjust them in 10 mins just by reaching underneath.
They shouldn't be loose enough to be done by hand, generally a socket & spanner job, hence why the wheels need to come off - to get enough access to tighten properly.
I won't be far behind you as i will be tracking the GT2 in August.
My plan is to put the settings back to factory minus the camber settings for the Corsa's , set the pressures to 2bar front 2.5bar rear hot, then find out what the car wants to do.
From then on, it will be a decision about toe, ride height, roll bar and tyre pressure.
I agree with the comment that your can drive around a lot with the Porsche, power on understeer i had with 993TT, cured with more -ve camber and zero toe to the front, courtesy of ninemeister, could have gone more aggressive but you still need a wet/dry set up in UK.
Let me know how you get on...
