honestly I wouldn't buy the megan racing springs either. Just wait till someone is sellin some used springs like tein's or ksports or some of the other well know brands. or just spend the extra $50 and get a new set of tein's off ebay. Honestly even though you may think thats enough of a drop for you now it won't be for long. I bought my tein's and only had them on for like 2 months before I wanted to go lower. Save yourself some money in the long run and just find a good deal on some used coilovers, that way when you decide you wanna be slammed you just gotta go adjust them lower.
just my $0.02
