Oh, wait, are you referring to 23 out of 30? I thought you meant 23F and 30R.

oh nonono..
i will set them all the same i set them at 20 now
and i love the ride ..
BUT
I think i didnt go with 230MM for the rear spring.. and my max height is still tuck in( the rear)... cant even put a finger in... is that right if i didnt get the 230mm springs?
or if there's other way to make it higher???

lets see PICS!!! ^^ wheels in?

not yet ... still waiting for it.
i order the titanium ones ^^
but right now im afraid will have rubbing problem since the back cant go higher....

Ah, got it. If you didn't specify anything, the rear springs are likely 210mm and you're stuck at its maximum height. Stiffening up the dampers won't increase the ride height.

Try contacting BC and see if they'll do a swap. I know they allowed it to some extent for those who didn't know a 12k spring was available for the fronts.

For all you who have had these BC installed, whats your current dampening setup? I have mine setup at the softest setting and enjoy the comfy ride but will probably wind up setting them at the 10-15 range.

i have 20F 25R i think? although it may be the other way around lol i cant remember.

Ohh they look sweet, congrats how much are they anyway?

Sorry to thread jack but I recently ordered my BC coilovers after reading this thread and received my order today. My concerns were after reading around on this forum and saw that a lot of the guys had experienced the rear to sit really low when at "Maximum" height.

After seeing soundmike's specified rear spring rate selection I was convinced that this would be a remedy to allow the rear to go a little higher at "Maximum" height. I noticed that on my kit (07+ g35/g37 sedan RWD) it displays on the box to have a spring rate of....F 12kg/mm and R 10kg/mm. The actual rear spring displays "230mm/10k" on it if it and no markings on the front springs helps anything.


I'm curious with my spring rate specs that I have will it make the car ride harsh, bounce too much, or is it just fine the way it is. Keep in mind on BC Racing's website the Application chart (http://www.bcracing-na.com/downloads...ATION_LIST.pdf) shows on page 3 "INFINITI 07+ G37" to have the following spring rates:

F 220L 12k

R 230L 8k

Anybody with personal experience with their BC Coilovers being low at max height please chime in or any suspension guru for that matter. What was your remedy? Thanks in advance.

10k is certainly stiffer than 8k, and 8k is already plenty stiff IMHO. I can't say much for harshness however (stiff != harsh). IIRC, BC recommends the 10k for our cars.

I have not installed mine yet, but just knowing that the default rear springs are 210mm and that we have the 230's tell me it will sit higher for sure.

Sweet thanks for the response bro. Well if BC recommends it then I'm fine with that. Since stiff = harsh then i'll just have to adjust my dampning level accordingly.

I won't have these installed yet since I'm still shopping for 19" tires for my new set of wheels. There's no point to tweak my alignment/camber twice because I'm still running my stock 18" sport wheels.

No prob. Btw, stiff != harsh. You can have a stiff ride and not be harsh.

Good luck with the install! I'm hoping to put mine on before the 4th of July.

Thanks and good luck to you as well. I'm aiming to have the suspension and new wheels installed by the end of the month. It all falls in the hands of my buddy's shop if there's an available lift for us to work in.

Where did you order them from?

And with the 230 mm springs, how high does it go in the back?

Thanks!

Judging from measurements done by another 2nd genner, the highest his rear 210mm springs went was roughly 3/4" lower than my stock ride height. The 230mm spring is roughly another 3/4" higher.
