Koni question...

[Nismoboy1]

I understand that some of you guys use the longer Koni Maxima rears with GC coil-overs on your P11. Should this go the same with just standard lowering springs, for instance the Eibach pro-kits, or should I just use the plain Primera(p11) rears with the prokits. and what's the difference between the two shocks. thanx.

with the new upper strut mounts that are fabricated for the gc's there is not enough thread on the shock piston to put everything back together safely... the maxima shocks have a longer thread area.

you dont need the maxima rears for standard springs, as you will use the stock upper strut mounts.

i believe Primeraman has front and rear P11 Koni's on Eibachs...

So are the rear struts for P11 and Maxima basically indentical , except the thread length of the rod?

[b-b00gie]

i'm not sure of the actual length, but someone at koni worked with someone at my local shop to find struts as close to the p11 rears as possible... i think the 95-98 maxima shocks were like 1 or 2 mm longer overall... no difference really.. =)

[Nismoboy1]

so the rears are almost identical, what about the valving on these, which is stiffer/softer? I'm thinking I might get the maxima ones b/c those are prolly easier to obtain then the primera ones. Maxima ones will work with standard springs though right? for some reason I think they wont b/c the spring perch could be a different width then the primera ones. If not i prolly just get the primera ones thanx for your all your help.

[b-b00gie]

well, you're gonna need the P11 fronts anyway, so i dont think getting the P11 rears will be much more trouble... not sure on the valving question...

if you have trouble finding them i can get you some help...

[Nismoboy1]

tru tru, u got me on that one lol i think i'll just get the primera rears and be done with it...

not to worry though, I was the one that e-mailed you about some suspension stuff a few days ago and you gave me a number to call...so it looks like I know what I want, now its just a matter of "who" I have to do for money now j/k Thanx for all you help again, as always

[b-b00gie]

no problem. :sun:

I just put some Koni's (Primera rears) in with Intrax springs a few weeks ago on my '99. The thread on the rears were too short to put everything back on. I had to cut some bushings in half just to get the top assembly back on. With the help of an impact wrench at 100+ psi, I got the nut down just far enough to get the lock part on the thread.

Since I had to do that the back is sitting a little lower than when I was riding on Intrax w/stock shocks. Now my 18's are tucked up in the wheel well and rub up against something when I hit harder bumps (which never happened before). This wasn't exactly what I was looking for when I bought the things. It sounds like the Maxima one's worked pretty well for most people. If I had to do it again, I would go with those.

i talked to a mechanic at my local dealer today, and he told me that there IS in fact differences in the suspension for north american primeras... ie.. G20's. that may explain why there's been numerous people (including myself) who have had problems with the rear p11 koni's.

i thought the problem was from the upper strut mount GC made for me, but i guess its just the strut itself, as G-Funk has stated he's using Intrax springs with obviously the original upper strut mounts.

i also want to point out that w/ the GC's i could get the assembley together.. but barely.. just as G-Funk described.. so i didnt think that was too safe...

bottem line... if you want koni's, get the p11 fronts and the 95 maxima rears ...if you live in north america

For me the most concern is, does the length of the strut ( from the spring seat to the bolt hole ) the same, if it doesn't, the rear of the car will get lift up ( I am using Pro kit ), if just a couple mm different, then I don't worry about it.

[Nismoboy1]

I dont think it will lift any cause the springs is what the car sits on, the shocks just dampens it, has nothing to do with height changes, the only I would worry about is the suspension travel, if the casing of the rear Maxima damper is shorter than the primera dampers then you'll probably gain travel, if longer, then you lose travel, if the same don't worry about it.

Ok, one question, since we all know now that the Maxima rears are the way to go, does anyone know for sure if a p11 aftermarket spring would fit on the perches of these shocks b/c I was thinking that the regular p11 lowering springs could be wider or smaller than a Maxima spring, so it might not work and GC's have only one diameter, the reason why these work is b/c these have a threaded collar that sit on the shock itself not the spring. Just wondering...thanx.

[Kenny-G]

Actually it will lift the car up if the length of " below the spring" part is too long. It is like when you have coil-over, you adjust the ride height by lengthen or shorten the length of " below the spring" part of the strut. So I really need a sure answer before I go for the Maxima rear struts.
