Installed the JIC carbon fiber strut brace and RS*R springs onto the Z. Tons of pics and complete how-to here for anybody interested:

Wow great info! The RSR springs really seem like a perfect drop for 19s. How was the alignment rear camber in spec?

 

Actually to be completely honest, I wish the rear would lower another .1-.2 inches in terms of at least looks. The front looks perfect, but the rear can go a little more.

Also, the alignment actually hasn't changed much. We've had the springs on for months (1,000's of miles) with NO alignment, and uneven tire wear. A vendor on here stated that he installed these springs, and a few 100 miles later checked the alignment, and it was still in spec.

 

I'm suprised you didn't have camber problems. I just installed Tein springs which have a very similar drop and after only a couple weeks and a couple hundred miles i can see my wheels are slanted. I'm getting new wheels very soon so that is why i'm waiting to get an alignment. I was also curious if you have any noises coming from the front springs now. I get occaisional pops and clicks coming from up front, but all the bolts are tight. Any ideas?

 

Yeah it's probably been at least 5,000 miles since the springs have been installed, with definitely no problems. Not sure what would make the Tein's any different though...

Your wheels will make no difference, so you can get your alignment at any time.

I haven't heard any sort of pops or clicks....when you/shop installed them, you guys re-installed the noise insulators, right?

 

I installed them with some friends and the Tein's came with their own insulators already on them. There was some other thread on here recently where people were saying that putting different wheels on would change the alignment because the nice wheels are much wider. This isn't true? I really have no idea about that stuff. Equally puzzled about those sounds. It drives perfectly fine but makes those sounds, although I have probably only put 200 miles on since the install so maybe they are settling in still?

 

There were things on the teins that looked like noise insulators, so i assume they were.

 

Its recommended that you should get an alignment when you switch to new tires, because of tire feathering, which is the situation I'm in. My stock 18's roar like crazy, and I don't want this to happen to my Falkens. I'm going to wait though until after I install my springs.

 

Yeah, i was going to do it just to make sure i get as even wear as i can. Also because i got this little coupon from nissan the other day (80 for an alignment), also got a coupon for a free check on all fluids. Waiting till i get wheels though

 

how does the JIC bar feel over stock? the same?

 

Check out the article (link in first post)...my opinion is in the first couple paragraphs

 

Car and website coming along nicely man!

Keep it up!
