Set them to these settings to start with.

1.5 degrees negative camber.

0 degrees 30 minutes toe IN.

That is the Grp A RS Turbo (Series 1) settings which will make it more stable on a straights but the tur in won't be as keen.

If you want to try the settings for a twisty track, set the toe to this..

0 degrees 30 minutes toe OUT.

That will make it more nervous in a straight but down the lanes, it will turn in really sharp.

In case you are having a 4 wheel alignment here are the other recommeded settings..

2 1/2 degrees positive castor.

Rear.

0 degrees 30 minutes toe in.
1 1/2 to 2 degrees negative camber

You may not like how the car performs on these settings though (they are for a competition car) so you may need to play around with it to suit your driving style.
