if you got a full set of new shocks... what make are they? and are they shorter and uprated, if not you'd have been better off getting a full set of Eibach shocks and springs, i would recomment NOT to go for a drop as low as 60mm without shortened shocks, as this could cause the shocks to leak and have to buy new ones again!, with un-shortened and uprated shocks id do a 30mm drop MAX!, if they are shortened, then 60mm is fine, it would get your front tires to just about level with the arch i should think
PS the reason i would go for Eibach springs is beause they have a lifetime guarentee unlike most which have just the 12month Guarentee
