I think i would run bosch adjustables before getting those tripe! seriously though i know you said your on a tight budget but just save a little bit more for a decent set of lowering springs! and imo a 60mm drop on oem shocks is too much and will wear them out quicker.
agree with elchunk, cheap sh*t. livvy has coilovers for 350. well worth spendin extra on. 60mm drop on standard shocks. will handle rough and blow the shocks in no time
buying anything off ebay especially suspension is always a risk, i have fallen into the trap a few times in the past! As said above buying lowering springs will knacker ur bushes, shocks etc within 6 months and the handling will be awful! its better to buy some coilovers for a bit more
