what are you finding difficult? You wind them down with a set of c-spanners, and lock them in place, job done. people have confused you by mentioning the top mounts with adjustment, this merely gives you the ability you adjust the dampening, not the ride height. ride height is always ONLY adjustable by winding down the collars (be it up or down), anything on the top mount (adjustable screw etc) will only be for changing the rebound of the shocks internally, nothing to do with the height. wind them all the way up, lock em on, sit the car down, drive it about (so that they can settle, it wont sit properly straight away as it'll always seem so high after removing them, they need a mile or two driving to settle down), then do the same in the other direction, lock them in place, drive about, then compare the right heights, you'll then know which way you have to wind them to raise or lower the ride height Tein HA's 'should' be damper adjustable, its the HR's which are only height adjustable, so yours should have rebound damper adjustment on the top mounts if they are HA's, but this doesn't necessarily mean they have camber adjustable top mounts, as this is something different again.
