i got my JIC FLTA2 installed and my fender rolled yesterday at kartoyz, Chad was such a nice and helpful guy. people works there are friendly and very informative.
i strongly recommend this place for the z owners, BTW they are located in Fremont, CA
heres the site: www.kartoyz.com

well, the JIC suspensions are great, improves handling a lot. i can take corners at higher speed now, no doubt.
but the problem is, they rattle like crazy. slow, fast, local, freeway, they rattle all the time. that noise is killing me!
anyone know how to fix the problem?

appreciate for all inputs

 

I've heard of this before with the Subura folks....this is what is keeping myself away from the Jic's

 

i have this problem too
i have JIC upper rubber mounts and i even put the oem lower rubber mounts under the spring perch but can't solve the problem
anyone can help us here?

 

i believe there are many jic flta2 users out there......

 

I heard the kit looks like a universal kit. I think that the rattles are common with the JIC's.

 

The JICs rattle, so do the Teins. There is always a compromise of some sort when you modify the suspension...

 

For me the noise is inside the car not outside. But the Jics work awesome. I cant really say the coilovers are noisy themselves?

 

john, yours rattle too? thats sad
i had a ride in my friend's z which has the JIC, it doesnt rattle at all! nice and smooth!

overall i love the JIC, now my z is the best handling car i have ever driven. but the clunking noise is just killing me

 

i guess no one has a solution for that....?

 

The solution is to throw away your JIC's.

 

u gotta be kidding...

 

Nope, cuz thats what im gonna do!

Not only do they rattle, but all 4 shocks blew out on me. Within 5k miles

 

so what are u getting instead?
i love how the JIC performs and i guess it is the best out there?

 

For any of you guys that are not happy with your current coilovers, I highly recommend the KW's. I have them on my car and I just love them. They have zero rattles and zero bounce. That combined with the independant rebound and compression settings just makes them an awesome setup. I can't wait to get them to the track. So far they have stood up to everything I have put them through.

I also have a group buy running on these as well in the Group Buy forum.

If anybody is intersted in getting a set for a great price just so I'm not the only one raving about these coilovers, let me know and I will hook you up with a good deal.

Also, I forgot to mention that the KW's have a lifetime warranty. If they ever do develop any problems, KW will fix them free of charge!

i was told that the shocks have to be adjusted too after adjusting the spring perch
i now have my spring perch at the lowest positon, i will try to lower the shock tubes too
anyone try this? did it work?

can't stand the rattling....

 

If any of you guys live in the L.A. area, visit Zeil motorsports(official JIC -USA distributor). Mine were rattling a little bit, so I went to them. I also had them do my alignment and I replaced the rear springs with 9kg/mm. They said that some things needed to be tightened. It doesn't rattle anymore. FYI, I also heard there were two types of JIC suspension for the Z. I also learned the hard way after they aligned the car I had to reset the steering position sensor...wierd.

 

it would be great if u can ask them for us how to fix it and what to tighten

 

Check out this post .... this guy seems to know how to fix the rattle.
