PLEASE HAVE MERCY!
I read as many of the threads I could regarding this issue esp the most recent one...

I have an 04 non-sport sedan with Coupe OEM 19's
F: 283 R: 308 (thanks to Gsedan35)

my main goal is to maintain handling & ride quality and NOT blow my struts!

what if I am happy with my rear fender gap with my new 19s'

1) Can I drop the front alone, with revised Z springs & Shocks

will i suffer handling problems?

For those of you with mercy...please help me

If you drop it without sport shocks, your gonna blow them sooner than later. If you really want ride quality and handling you gotta upgrade your shocks. Trust me, I did this on my Maxima (no sport pkg shocks with 1.5" drop) and my shocks were worthless soon after.

How do you have an '04 sedan w/ OEM 19's? Are they coupe 19's?

From what I've read & researched, you'll have to go with option #2. I too have an '04 non-sport sedan, but with aftermarket 19's. To sum up what I've learned & from what I actually recently purchased & will be installing this weekend, if you drop your car, you WILL need to replace the shocks with at a minimum, the coupe or Z shocks & struts, if going w/ coupe or z-springs.

I may already be repeating what you know, but the setup of z springs up front & coupe springs in the rear will drop your car 1" up front and 1/2" in the rear (to even out the fender gap)....both front & rear will need different shocks/struts to work with them & in order to last. Jameyb has some GREAT picts of his before & after install of same, along with some tape measure readings of both. Search & you'll find it.

Good luck.

I have a better idea.
Revised Z springs And shocks front, Tein H-tech rear springs.
You'll get a 1"/.7" drop instead of a 1"/0" drop.

Though I'm not sure why you aren't considering oem revised Z shocks front and rear on unrevised oem Z springs front and rear for a 1"/1" drop.
