Ste is right - I do!
The manual setting of 8mm results in the bellcranks pointing in, this makes the car feel extrordinarily safe as it reduces the turn in. The starting point should be bellcranks parallel - then you can shorten that link to reduce turn in, or lengthen it to make it feel more aggressive.
Make changes by a 180degree turn at a time. Pop off this link, put a turnbuckle wrench on it, then turn the ballcups round, both end by 180 degree. Doing this will make a noticeable difference on the track - so what I suggest (and what I did), is spend a full race meeting just making small changes to this for each run until it feels great then leave it alone.
