Just out from under my new 05 GT3 and everthing looks good except nuts on anti-roll bars in rear look used. Car has had an alignment at dealer. What are the normal factory settings? My fronts are set at the most foreward position, rears are set in the second hole from the rear.
Many thanks, I need to know where to start before changing.

I think the factory setting is one from stiffest both front & rear.

The proper setting is very subjective based on a number of factors including how & where you drive, tires, alignment, etc. I went one notch softer in the rear (as some others here have also done) and that works well for me.

If you haven't done it already, make sure you re-torque them and put on some loctite. Almost everyone has had the front ones work their way loose, creating a clunking sound over bumps.

Holger B is right. The Factory setting is 1 from stiff in front and rear. With the stock suspension, I ran 1 from soft in front and 1 from stiff in rear, with -1.5 and -2.0 camber. This was primarily an AutoX setup to get more rotation. It's very much a personal preference, and has a lot to do with how you use the car.

Bob-ej I run factory setting in the front i.e. one hole from the highest (higher is stiffer) and one down from the factory setting in back. This allows me to get on the gas earlier ini high speed turns with less risk of power oversteer. I trail brake in slow turns to overcome the understeer. Note - autocross settings as described above might be dangerous on a high speed track!

Rgds,

Bob, I agree. Too much oversteer for high speed and smooth surfaced tracks. 1 from stiff (F) and 1 From stiff (R) are much more stable settings for track work.

Question, full stiff is closest to the bar itself, soft is furthest from the bar?

Yes

I run Full Stiff front and one from full stiff rear at the track.

For autocross, I keep the rear bar in the same position, move the front one to full soft.

The way to remember is just by imagining trying to twist the bar yourself.

or, the longer the bar the more flexible it is , the shorter the bar the stiffer it is.
