basically, lowering springs will wear your stock shocks more quickly. their life is inversely proportional to the drop. in other words, RB springs won't make too much of a difference in terms of shock life (because its a mild drop)...but the S-techs on the other hand..i wouldn't expect your shocks to last very long. in terms of performance, you will definitely notice the difference between being lowered on stock shocks vs. koni's! IMO, if you want a drastic drop, just do it properly and buy a new set of shocks as well. either that or get a set of coilovers.
