I have a chance of getting either of the 3 and I was just wondering which one is best in everyone's eyes. Which drops the lowest? And which are stiffest? Thanks in advance.

Well, I can help out a bit...I have the Neuspeed sport springs (the blue ones) They are a 1.3 front and 1.4" back. They settled to about 1.5-1.7" in the front and 1.5" in rear. They are pretty stiff, but not uncomfortable. I don't like Eibounce...I mean Eibach springs, they are too soft and bouncy. I have ridden in both springs and the Neuspeeds are the shit. My brother has the Neuspeed race springs on his rsx and those are an even firmer ride, it is nice and smooth, but the drop is a lil extreme like 2.0" and on eclipses that would equal no front bumper in a month or so. Well, hope that helps I would go with the Nuespeeds, but maybe not the race ones( the red ones), I also just have the KYB GR-2 shocks so with the ones you want, the ride may be a little different, cause my gr-2s are like the stock shocks, but I have been lowered on them for almost 2 years now and the shocks are still kick ass Good luck pally

Yeah, I'll probably get KYB's if I go with the Neuspeeds. So that's a good setup? How about this compared to the Tokico spring and shock set?

The most perfect set up i have heard and personally own is the tokico illumina struts and shocks with the progress 1.5 lowering springs.there is a web site that praises this specific set up. The important thing too remember is if you want good ride quality don't go any lower than an 1.5 maybe a 1.7. That's when you get into ruining struts and shocks. Believe me I am talking from personal experiance......this suspension set will actually give you a better ride than factory with the lowered look.,..hope that helped..

Okay, thanks a lot to everyone for their input. I got all the info I was looking for.
