Coilovers

ChrisSlicks · 05-09-2013, 06:34 AM

Noise in the rear is usually when the spring is to short, when you go over a bump the spring rattles since there isn't enough preload. BC has two spring lengths to offer for the rear, they seem to ship the short one by default but that causes problems unless you have a large drop.

Well I plan to have my nuts dragging so hopefully it will all work out

Or set a little extra pre-load. I set 3/8 rather then 1/4 and it was better. A 1/4 I heard a slight noise with on my 350z with those shorter revised springs.

I did maybe a 1.5 inch drop in the rear

Now I have Stance with the true coilover type in the rear and then added SPL toe arms and camber arms.

I want to bring this thread back to life because I've been trying my best to study up on this, but cannot get a clear answer from anyone.

I previously had a G37s with KW V3's and loved them. My car was flush, zero wheel gap, tire rubber tucked...etc. Even at this height, I had atleast 1 1/2" left on my perch that I could drop the car even more.

I continue to read that KW V3's are limited to how low you can adjust them on the 370. IS THIS TRUE? This is my single hold up from keeping me from purchasing KW's right now and its driving me nuts...I NEED to lower this Nismo ASAP!

I've flirted with Stance GR+ coils, Tein mono flex with EDFC as well. 2 of my local crew members run this and love it...adjusting their strut dampening on the go.

I do track events, Auto-X, and I also enjoy the afternoon cruise. I also attend ZdayZ( 17 hour drive) so with all of this taken into consideration, the Tein mono flex have really taken my interest.

I loved my KW's...so I'd really like to get the facts on this before I narrow my decision on going a different route.

This is Gene's 370 on KW V3's.....TBH, I don't know why you would ever want to go any lower then THIS???? Doesn't seem limiting to me?????

I think the KW's will go plenty low enough for most people. I do know that I've read that the KW's for the G go slightly lower that the Z, don't know this for a 100% though. But I can say that since installing my Stance SS+ and all the SPL arms in the back, I love them!

And I may be wrong but I think those are 20" wheels, so it appears to have a slightly better stance. I saw a few 370 pics with 19's and KW's thar were maxed out and the fender gap was barley closed up. I just didn't want to take the chance on them not going quiet as low as I'd like for them to.

Now that I actually did a little more digging I see that I can get brands like tein or tanabe for about the same or even a little less

ChrisSlicks · 05-05-2013, 09:26 AM

No problem here with the BC ER after 3 years on track, then again pot holes and city streets probably but more abuse on shocks than a race track does

^^ Your cautionary comments are valid and true, for the most part.

That said, for our cars, if you're lowered significantly, there isn't really any pre-load on the springs, so it's perfectly safe to adjust them.

This is for sure true in the front, and depending on setup, in the rear as well. Ever notice that if you loosen the shock nuts in the front, the nuts don't come up off of the tower? That's because the weight of the spindle/arms/brake/everything else assembly is pulling down on them because there's no assembly pre-load.

So for coilovers where you're adjusting a ride height adjustment that's independent of spring pre-load, you're just fine doing it on the car, as long as you can confirm there's no pressure on the assembly. (Which again you can confirm by loosening the top nuts and seeing if they stand up from the metal or if the shock just sinks down, keeping the nuts flush with the surface)

Correct, you can adjust the front on the car as long as all the load is off (basically leave the 3 bolts in the engine bay) the bottom bolt should be undone so the strut is free of all load.

So yes I agree with you

Annnnnybody??? Come on fellas, I know there's a ton of guys on here with KW V3's and Stance GR+

I currently have KW V3s on my Nismo. It took me about 3-4 months of research to decide on these coilovers and I cant explain how amazing they are. I have the damping set in the middle & is WAY more comfortable than stock. Paired up with Whiteline swaybars, the car feels planted & handles wonderfully with minimal body roll. Ill post pictures of my set-up when I get home, but I still need to drop the rear to match the front & and Im running out of threads already so if you are looking to SLAM the car to the ground then these aren't for you.

Finally some quality info on V3's on the 370! If you can post up a photo of your ride height, and even a photo of where you're coil is on the threads, I'd REALLY appreciate it!!!
