didnt want to start a new thread..

can brakes from an 07 sport sedan fit my 04 sedan? any special brackets needed?

 

Will 2005 6mt suspension (shocks/struts and springs) fit on a 2003?

 

^ Yes but drop would be very minimal if any. You should get the sport shocks/struts and pair them with a set of unrevised (2003-2004.5) 350z springs. That would give you a nice 1" drop all around if you're looking to reduce wheel gap slightly.

The sedan sport shocks/struts are identical to the 350z unrevised springs in terms of spring rates. I think their fronts are 314 & the rears 342 if my memory serves correctly. Look in the suspension subforum for verification.

 

I'm looking to sell my 05 suspesion and the guy wanting to buy it was asking if it will fit on his 03. Thanks for a quick reply.

 

Yes, it will fit. No performance/handling gains, though.

 

Maybe I missed it, but the REVISED stock 350Z springs will also drop the sedan 1" correct? My plan is to get the full revised (04.5+ I assume) suspension (shocks, springs, sways).

Is there a reason why people are going with the unrevised Z springs? Is it solely for comfort reasons?

 

^ Yes, drop is the same. The guys that go for unrevised springs have (or should have) sport sedans with the sport shocks that match up with the 342 rear spring rate.


Revised springs are at 427 in the rear I believe which would accelerate shock wear when paired with either sedan sport rear (342) or sedan nonsport rear shocks (308).



Just don't get a full unrevised (2003 - 2004.5) 350z suspension. Nissan revised it after owners' complaints of the shocks in those years being really bouncy. Also, a set of sport coupe springs for the rears (427) would give a more level drop as the wheel wells of the sedan are not even - you'd be dropped 1" in the front and 0.5" in the rear. <--- Known as the z/g coupe springs drop.

 

^Footnote:
Provided the coupe springs are not from a "Sport" coupe (all the ones with a 6MT, or 5AT with a sport package) because those are identical to Z rears.

 

^ I mentioned for him to get rear sport coupe springs for the z/g combo as he mentioned he was getting a full revised 350z suspension which would have the 427 rear spring rate shocks. Rear sport coupe springs would match that 427 rear rate and drop him 0.5" instead of a rear revised 350z spring drop of 1". Sport/nonsport coupe springs are only identical in front spring rate (308) & overall drop (0.5"). A rear nonsport coupe spring would not match up spring rate-wise with a revised 350z rear shock (342 vs. 427).

If he has a sport sedan (308/342), he wouldn't have to get a full revised suspension - with a z/g spring combo, a set or rear nonsport coupe springs (342) would work. I don't know what the effect of having a lower rate spring (342) on a higher rate shock (427) would be, tho.

^Regardless, in general match like spring rates with whatever shocks you wind up with and everything should be kosher.

 

^Sport coupe rears are not .5 they're 1" completely 100% identical to revised Z rears in both rate and length.
Trust me on this one, I've had both in hand side by side with a tape to compare. They're the same.
See how that list mentions the 05/06 cope with OEM 19s? Those come with the sport pkg. They ARE Z springs. Not just the same rate, but the same length/same drop
It's the OEM 17/18 coupe springs that lower it .5"

 

I was under the assumption that:

- All G35 Sedan springs and shocks, regardless of sport or non-sport, were 1" longer than 350Z springs/shocks; 0.5" longer than G35 Coupe shocks and springs, regardless if they're sport or non-sport. And that the only thing that varied within MODELS were spring rates, depending on sport or non-sport or revised/non-revised for the Z.

I also recall that the 05-07 G35 Coupe SPORT springs and shocks were identical in spring rates and dampening as the revised 350Z springs and shocks, but 0.5" longer.

 

Ashley - I'll bow to the guy who definitely has more wrench-time than me.....and his own automotive website/forum


I never had to deal with any of that as I have a sport sedan & never changed out my OEM sport shocks when doing the z/g spring combo. I just matched spring rates and went with nonsport coupe rear springs. Got rid of the uneven drop on my sedan at least. Wow, that was awhile back. 283,308,314,342,427 - still stuck in my head

 

So if that's the case (revised Z springs springs same length as 05-07 G-Coupe sport springs)...

How exactly can you do the Z/G combo when using 350Z revised SHOCKS/STRUTS on the front and rear? Does that mean you have to use 350Z revised springs along with the 350Z revised shocks up front, and 350Z revised shocks with G-Coupe non-sport springs in the rear? That doesn't seem optimal, given that the rear Z revised shocks are optimized for the 427 spring rates and springs that are 0.5 shorter.

Screw it, I think I'm just going with the full 350Z revised suspension and see from there. My shocks are already really worn out so they need to be changed anyhow.

Too bad I sold my 06 Couoe 6MT shocks/springs/sways a while back.

 

I've never payed close enough attention to the coupes with the sport pkg to see if they sit any lower, but trust me on this one.
After reading and reading and searching and reading, I too was convinced from this site to do the famous "Z/G drop" so I got my cousin's full suspension from his 04.5 350Z and ordered a set of coupe springs off of ebay.

I later found out the coupe was a 06 Sport, 6MT with OEM 19s

Imagine my surprise when the rear springs off the G, the springs I had gone through so much trouble to buy, were completely, entirely, 100% identical to the revised Z rears

The fronts were different though, go figure on that one I guess

Anyway, I ended up just doing the full revised Z suspension, and I'm very happy with it.
Yes, it sits a bit lower in the back, but it's really not that bad.
Feel free to browse through my car pics to get an idea, or any of the other sedans running full revised Z suspension.


Also, in re: to your question about "How are you supposed to do the G/Z combo..."
I think what many people are doing is either swapping out springs only and keeping OEM shocks (Mostly Sedan Sport shocks) or using 350Z fronts pre-assembled with coupe rears and whatever rear shocks they end up with (either coupe/z/whatever)

I agree that ideally the springs and shocks should match though. And mine do.


Strictly speaking though, the ultimate solution is coils

 

Thank you.

And I had coils on my G-Coupe... HKS Hipermax III Sports. Sadly they stayed behind on my totaled Coupe, but got credited a reasonable price for them. But they were pretty damn stiff (671/615)... not going back to that on a DD. And yea, ideally coils would be the best route. But I'm on a strict budget for now.
