coilovers give u unlimited adjustability.
but they are problably hyper ds but they will be stupidly stiff and only make driving unconfortable. if you herdly even do track days then they arent worth it (only if ur drifting), and for track you wouldnt even want them, itd be better to use the SK bilsteins, which have grooves in them to adjust height.
but if al ur interested in is lowering ur car just get lowered springs... alot cheaper
