i was wondering if anyone could help me out with this situation...a friend of mine installed my coilovers for me last weekend and the way he installed the rear spring was with the adjustable pertch on the top of the spring so there is no rubber bushing in between the pertch and the car so it is metal to metal and is really annoying..now what i would like to know is if wether or not that is how it is supposed to be installed or if there is something to put between the two to get rid of all the clanking or does the pertch sit on the bottom with the stock rubber bushing sitting on top of the spring..any advice would help..i bought these used so i didnt get any instructions with them
TIA,

he did it right because thats the only thing available...
if you find it squeeky then use a layer of rubber matting...
im running the same way ur right now...

 

I am pretty sure there is supposed to be a rubber piece at both the top and bottom of the rear spring. The bottom rubber piece is removeable and has a "groove" in it that the spring fits into. The top rubber piece is fixed. If you have both rubber pieces on top with nothing on the bottom, that is wrong.

 

the coilover height adj seat sits on the bottom...
its metal... if you want to get less squeak, put some dampening material in between because the spring adj seat is just like that

 

does anyone know if the brand new kit comes with a rubber peice to go in between the pertch and the car and if there are brackets that come seperatley for the brake lines because there wasnt any on the front

 

Sorry for the wrong information in post 3. I guess I am not running a true "coilover" on the rear so it sounds like it was installed correctly.

 

u need to custom fabricate brake line holding brackets bro

 

no cuz if u run true coilover u wont have spring/adj perch etc etc
so u wont have this problem
...
u'll just have something similar to the fronts (coilover)
the type we're talking about is basically old school shocks and springs
lol

 

I don't know then, because the height adjustment perch for my Tein Basics sits on top of the spring. What kind of coilovers did you get? Tein has installation instructions online. http://www.tein.com/ti/inst/lp26u.pdf

 

i got a set of jic's im not sure what model but i tried looking for the install instructions online but no luck...and jic's website is down

 

the stock rubber peice that it shows on the tien instructions doesnt fit in the hole of the pertch in the jic's like it does in the tiens...i read somewhere that on the jic's its possible that the pertch could sit on the bottom...can anyone verify that?

 

i got the same thing
JIC FLTA2's
they only make FLTA2's for 350Z's
it comes with 2 front coilovers,
2 rear shocks + springs + perches
+ adj hex tools
thats it...
its the correct installation

 

so i shouldnt try swithching the setup and just put a thin piece of rubber between the pertch and the car?

 

seee how u like the ride
i got used to it...
in the beginning u'll hear rattles and squeaks everywhere
cuz JICs are probably THE harshest coilovers anyone ever released for the Z

 

well i can stand the stiffness but i cant sount the metal to metal sound and it only seems to be coming from the passenger side so i guess ill try to put some rubber in between to see how that helps

 

you got on-rails handlings now you gotta compromise xD

 

yeah i know...so i found out today that the perch needs to be connected to the car by drilling holes through them and the car then bolted down..dont know if i want to do that..i guess ill just try to add a thin peice of rubber in between the two and just live with whatever noise is left

 

thanx for all the helpfull info you guys
