Generally placed towards the center of the track. Adjust so that the jib tell tails "break" evenly. Sail on an upwind course and sheet the jib in. Then start turning the boat into the wind. If the top tell tail on the windward side streams up first, move the jib car forward. If the top tell tail on the leeward side streams up, then move the car aft.
In high wind, you can move them back a few inches to allow the top of the jib to twist open and spill some power. Downwind, you can slide them all the way forward in the track to keep the top of the jib from opening up too much (or in light wind you can just have your crew sit on the low side and hand hold the jib).

Thanks sm but my problem is the actual track position on the hull. The front end of the track starts at the back of the dagger board case. I posted on FB last night and someone replied theirs was 720mm, mine is 885mm, measured from the back of the front beam.
