Bought these brand new from Injected Performance last week.

 

Mine don't have the gold pieces that fit into the oem spring bucket either. I could tuck the wheel up in my fender if I wanted, but i can't even get it to raise any higher than that which sucks.

I tried calling BC Racing about a million times and he will never answer nor return the message I left for them.

 

Here is an application list for the ER Series, that's the most similar spring number I could find:

I would assume the difference between 008 and 010 is the spring rate.

 

Better yet:

Everyone of the BR Series say you should have a 230L-8K spring and you obviously have a 210L-8K, which is found on the 08+ FairladyZ/370Z Z34 a few lines below.

 

hmmmm good find, hopefully this is my problem.

 

Good luck.

 

Thanks for helping.

 

Isn't there a rubber spring isolater you are supposed to have on the spring? Shoud be on the bottem of the spring going into the bucket.

 

This is a very disconcerting problem. This isn't making me very confident in installing these coilovers. I too have the same number coilover "62 97 210 008". This just makes me mad because the only reason I bought these coilovers is because they were adjustable. I hope I didn't get the wrong spring as well.

Maybe your best bet is to take it to your local tuning shop and have them look at the problem.

Definitely keep this thread updated I am very interested, I'll do some searching of my own. Best of luck finding the problem.

 

i have bc racing logging on here to address it

 

I spoke to BC Racing this morning. Gonna try a few things that he mentioned. I'll let you guys know.

 

BC Racing said that I had the springs preloaded too much and was compressing the springs too much. I'll update after I try what they told me to do to fix it.

 

Hey everyone.


Independent rear setups can be tricky even for certified tech not having done a install on one before. In all honesty it is really simple though. In Filthys pictures you can automatically see the coils are very close to each other and based on the conversation one of the techs had with him, there is way to much load on that spring. On the independent rears you want to set your rear shock in place. Simply bolt the 2 upper nuts and leave the lower mount disconnected for the moment. Remove the oem upper rubber cup in the spring area. The lower oem rubber cup will be used on the BC supplied spring. The adjustment piece with the 2 gold rings is what adjust your ride height. You want to adjust these rings until you achieve the height you want. But here is the catch to make this simple. Adjust the height about 1/4 inches higher than you want. You are going to use that extra 1/4 in to preload your spring. Once your height is achieved 1/4inches higher than wanted. You want to grab a jack and raise the spring bucket up to compress the spring that 1/4 inch. Now you can shorten or lengthen the shock until the lower mount is long or short enough to pass the bolt through. Since the shock is at full extension, when bolted in place the spring cannot loose the load you locked in.

For a example, Filthy's picture shows that the spring was compressed with a jack and the shock is at full extension holding the spring from unloading. If he rotates the lower mount in the shock say 1 inch, it will unload that spring 1 inch and in turn raise the car. In this circumstance he is rotating to lengthen the shock.

For those with ?'s on the 210 and 230 springs. The 210 was highly requested to allow for a further drop. The drop on the z platform 03+ on a 210 spring will allow the user to tuck tire and raise the vehicle above the tire/fender mark with no problems. We switched from the 230 for that specific reason. For those of you not wanting to tuck tire, you still have the ability to raise this quite a bit without any issues.

Let me know if there are any ?'s

 

Thanks for clearing it up Pete. Missed your phone call just a minute ago, but I'm gonna be heading out to the garage to fix this issue. I'll let you know when I'm finished.

 

Tim also emailed me those instructions this morning because i was having the same problem with adjusting the rear shock, theres really no way to know how to do it unless youve dealt with 2 part rear coils before

 

Well I done exactly as BC told me. It def improved the ride quality, but I'm still slammed and I have the it almost maxed out still.

 

LOL. The directions say to adjust it to 1/4 inch higher than you want, but you're already maxed out on spring adjustment.

Try seeing how the car sits without the damper attached?

 

I done exactly what BC told me to do, take the shock off and let it sit with the spring only. The spring really wasn't compressed all that much. When I jacked the car up and took out the bolt for the shock it didn't fall very far at all. I put the rubber piece back in the bottom of the spring as he told me to do. I followed step by step and the end result is almost the same. Except the ride quality has been greatly improved.

 

glad to hear it. they are great to work with and really stand by their products!

 

The problem isn't fixed yet though. Still have the problem with it be too low. I have to send more pictures to BC Racing. See if we can solve it.
