i got the megans on mine too. the only thing i would trade my current set up for is a complete awr coilover set. spring rates are 280 fr and 230 rear. roughly 2.5-3X stiffer than stock. yeah, its not a full 2 inch drop but i love them. with such high spring rates, i choose to run the illuminas too. the hp's may have worked, but the msp struts wouldnt have cut it.
i also got these because of the increased spring rates. sure lowering the car improves handling, but with dropping the car, and increasing the spring rates quite a bit will do more for handling than sprint or even eibach springs.
so yeah, if you plan on getting the megans, spring for the illuminas. i got mine on ebay for 440 shipped. i dont remember who the seller was but its a great deal
