Attention All BC Racing Coilover Guys, Check your Rears--Possible Install Error...
#106
Based off the installation guide that I'll post, I'd like those that are having the rattle verify first everything is installed properly. I personally feel the rattle has to be due to the rear spring assembly. I'll demonstrate in the guide how to keep it tight. Lets try the to eliminate the installation part first. I really believe the springs settled and the rattle is attributed to them being a bit loose. But, I'll need those with the problem to work with me on diagnosing. If I was there it would be much easier.

UPDATE:
I tore everything down on my passenger side again, and just took it for a spin. For now, there is no rattle. The only problem is that because I unbolted everything and checked assembly, I don't know what or if I fixed the issue. It took a couple days for it to creep back up after first assembly, so I will wait and see.
BG: I've been posting info trying to help for a couple days and haven't really heard anything. I haven't driven my car in a week. You HAVE to understand that my patients have been wearing thin because of it. When I have something installed with no real instructions and then end up with a rattle followed by a day of wondering if my spring is upside down and haven't driven in a week waiting, I'm just empty on this situation. I'm not saying the guy hasn't been here every other day, it's just frustrating to go days without anything, you know?

Also since I was bored, I decided to drop the front down. To confirm since the boxed instructions stink, to lower the front do I just loosen the 2nd collar at the top and get it out of the way, then crank the top collar down to the height I want? This obviously dropped it down, but the boxed instructions SEEM to indicate spinning the entire assembly which I couldn't do. Basically they make it sound like you can spin it like you can the back shock. Can anyone confirm?

you could try putting your jack under your suspension, lift the suspension up some to take the weight off of it, and see if you can spin the whole thing then like you were trying

The one thing that I think everyone needs to remember is that items like your suspension or brakes are very important to how the car functions... If you are unsure about how things should go on... might be over your head or at a minimum it is time to ask a friend for help... I put mine on with no problems at all... The install we pretty much identical to other brand coilovers that I have installed on other cars for my self and for friends. This includes many G35's, 350Z's and a TEIN Flex w/ EDFC on my personal 350z.
The G37 is extremely similar to the G35 and 350z... but there are differences.. one of them includes the 19 mm nut on the front that I posted a thread about... it is a PITA to get off... but even more important is getting that nut back on and torqued back to 120 ft/lbs.... If you have rattle and you did not use a torque wrench or even if you do not have a rattle... then you need to go get one and recheck every bolt and nut.

As everyones been waiting for. Look it over carefully. I need some help with you guys on the front bolt sizes. I posted what I can remember on the sizes. Help me out if this nut sizes are wrong. I'll make the necessary changes. The pictures should be helpful. On my next post I'll explain how to preload the front springs if anyone tampered with the preload already. Also, springs settle and can become a bit loose. So if your getting any noise in the front. It's a good idea to go over it and make sure preload is up to par.
Thanks again for everyones patience, time for lunch
