arb

[xantiaman1]

I've just purchased a z4 that has an unfinished coilover set up, its all fitted now apart from the adjustable arb links, my question is... to set up these links with no pre load the roll bar needs to be at its natural resting position but as the roll bar was not fitted to the vehicle, it now is, I do not know what the natural resting position is, are the ends of the bar horizontal with the ground or do they point up or down?

any info gratefully received
