Has anybody put G35 Coupe Spring on there sedan? I only hear about the
350Z but what about the G35 Coupe? help me out.. I check out the old post but no answer.

 

yes i have the coupe springs. They only drop the car 1/2 inch but are stiffer than the non sport springs. I like it because it keeps the alignment pretty close to sedan spec. Many go the route with the coupe spring rear and the 350z front. It looks a bit better in my opinion with the front wheel wells so high. I advise not to go with the 427 rate spring in back... I had those for awhile and they were too bouncy even with tokico blue struts. I feel it takes away from the sedan smoothness. To each his own though

 

what is 427 rate spring in back? Do you have any pix of ur G?

 

the sport springs for the coupe (with 19" rims) and revised z springs (meaning year 2004.5 and up) have rear springs that are rated at 427 vs. 340ish for non sport coupes and earlier 350z's. They are extremely bouncy in my opinion. I'm not 100 percent sure but I think the stock sport struts for the 6mt sedan can't handle the 427 springs too well. They aren't properly designed to run together. I think the dampening isn't stong enough... anyway i dont have pics right now. pm me later

 

I'm running 350z revised springs in the front and sport G coupe springs in the rear... So far, so good. I don't find it ridiculously bouncy at all. I'll be sure to take pics soon and PM you a couple... it's snowing here now and I don't feel like going out there with a camera lol

 

im running hotchkiss 350z spring in front, and 427 oem 350z spring in the back. all on oem 350z struts.

also have hotchkiss sway bars front and back (front full stiff, rear medium stiff)

car isnt bouncy at all. AND HANDLES LIKE A GO KART!!!

 

Take a look at the sticky in the suspension forum.
Link here: Clicky Pow

It goes through the topic in depth - gives spring rates and effective drop for coupe and z springs on the sedans. I went w/ unrevised z springs all around. Since I had a sport suspension on my sedan, the OEM spring rate was identical to the early year z (i.e. no need to swap shocks). I'll probably end up throwing coupe rear springs (not the 427 rate) on for a more even-looking drop (and to fit the 19s w/o 35series tires or a fender roll)
Based on your username, it looks like you have the sport suspension as well (all 6mts had the sport suspension), so you can go the same route. $50 and 2 hours and you have a nice drop. Don't even need spring compressors for the job.


Good luck!

 

thank for da 411!!

 

reading material for you.

there is no revised front z spring. Revised refers to the rear spring that went from 342 to 427 hence the revision.

The fronts were always and are now and will always be 314 lb spring rate.

If you are talking about running oem 19s on cpe rears without using 35 series tires--I recommend that you roll the fender lips. I have the fender lips rolled for precaution and I have 35 series tires that handle well and have a very good ride. My advice is especially true if you carry adult rear passengers and are lowering the car even with cpe rear springs. If you are not talking about oem rays, nevermind!

 

I am talking about the OEM 19s. I'm going to find a set w/ decent OEM tires and throw them on the car (w/ the coupe rear springs). If they rub, I'll def end up rolling the fender lips. I really need to find some of these wheels. Pics of your car make me want them yesterday.

 

thx! Btw, if you get a fender roll down the road--make sure to go to a place that uses a hub-mounted (lip-rolling) tool and that they use a heat gun before to soften the paint/metal and that they go reals slows

good luck.

 

For reference. I am on revised 07 z suspension/ springs in front and coupe springs in the rear. Awesome ride. Little bit harsher than stock, but a good kind of harsh. Makes you feel more in tune with the car and makes it live up to the name sports sedan. Also, I am running the same rim/tire size/suspension setup as texan 1, but I do NOT have any fenders rolled. It's not neccessary to do so, unless you want to be precautionary. I rubbed once on the right passanger rear side when my car was full with 200 pound dudes in it when I went over a huge dip. Other than that, never rubbed or ever came close what-so-ever. Just something to think about. Some pics for reference...

 

No way man - baseball bat in 40 degree weather w/ no heat gun.
