Not everyone wants a slammed look. Not everyone can drop +1K on a coil over set up. Not everyone needs the adjustability nor has the knowledge or the time to play with the adjustability of a coil over set up. Lastly, it has never been proven that an aftermarket spring causes premature shock/strut failure for G37's.

You are correct in labor if you're not doing it yourself. However, some people prefer to do their own work...so that really isn't valid either.

Just sayin'

 

damnit ive been trying to write this post a couple times but hit the back/forward or reload buttons by accident! arg

anyway, youre right that not everybody needs those things but i disagree on a couple other statements. it has been proven that regardless of the platform, lowering springs will wear out oem shocks faster than oem springs.

in my opinion, a car doesnt have to be slammed to look good, but lowering springs will leave too much of a gap still and when you combine that with the low profile tire on a 20" rim, it will look like crap. not to mention that it will also ride like crap because there will be too much suspension travel (too low a spring rate, not enough damping force from oem shocks).

and i think i'm right on the labor issue even if you do your own work (which I do). I would still be pissed about having to do the same job twice if i got springs and then later decided to upgrade to coilovers. its not solely about the money, its also about you being able to spend your time elsewhere.

 

You should also ask yourself if you drive aggressively enough to take advantage of coil overs and their adjustability.

I've never had the need to switch from my Eibach springs to coil overs on my daily driver.
