to me sleeve kits are the same as a set of springs nothing different, they just cost more. plus how many times do you play with the ride high? your going to set it and most likely never touch it again. save yourself some money and buy RS sports with e36 bump if you looking for stance or go straight to coilovers if you want them for track reasons.
