you do not need to turn the damping all the way up, people tend to start very soft on damping and then go towards harder as they tune. People rarely ever turn their damping all the way up unless there is a reason for competition use.

 

Agreed however when somebody says that the suspension setup is soft i assume that they mean the entire setup is soft (ie the car will lean in corners, lack of valving). Smooth ride to me doesn't equal a soft ride. A soft ride would suck (lean) but a smooth ride (which is still stiff) is good. So any thoughts from those that have these installed?

Wow, to get a nice ride we need to turn them up all the way! that blows.

 

Some comments on the damping issue:

I spoke with someone at K-Sport on the phone and he indicated that for a certain set of valving parameters there is a range of spring rates that it can handle properly. Note that valving and damping are not the same; damping is how much overall force the shock applies to prevent unnecessary movement, and valving is how the shock reacts to high forces vs. soft forces. Anyway, the guy I spoke with indicated that when you go above or below a certain spring rate, you have to change the valving... maybe 9/6 is just on the upper end of what the shocks can accomodate with their valving, so you have to dial in high amounts of damping.

Of course, it could also just be that the shocks need to break in first, and once they're broken in, you don't need full damping.

PEOPLE WHO HAVE THESE INSTALLED: WE NEED YOUR FEEDBACK AFTER SOME MILEAGE. PLEASE DON'T FORGET ABOUT US!

I think it's safe to say that if you're a real stickler for comfort (although I'm not sure why you'd be buying coilovers if you were), you could go with 7/5 springs and have a good range of damping to play with. Of course, you'd probably sacrifice a lot of handling, and that setup would be more understeer-biased, but hey... good to know we have the choice, right?

 

well guys i just fiddled with the dampening to day, and the bouncyness is gone, oh man am i happy, it still rides pretty nice, all i did was put the rears up some more, cuz that was where the bouncyness was coming from,

i figured out that there aer 4 full turns for the rear struts from Hard to Soft, so at the moment i have them turned 1 Full turn away from Hard, and it got rid of the bouncyness, i will fiddle with it next week after a bit of settling time. But at the moment i have these things slammed down, 2 finger gap ALL around, and oh man, its so sexy... haha

But like Doodfood said if your a stickler for comfort, dont even bother with coilovers, no matter what it will be a little rougher. I really do like the ride that these give me, and i have give 3 people rides, and they all like it a lot. and are all maxima owners.

also if you look at the pics that dave put up, my rear end is a little higher, i fixed that today, they are pretty much even now, and it looks so nice. I will be taking pics of my car tomarrow after work, i forgot to grab my camera before heading to daves house, so i dont have pics of the top mounts, i will do that also tomarrow.

 

The comment about the ride with the K-Sports being "softer than stock" was subjective. We all know that's impossible since the K-Sports have spring rates that are a few times higher than stock. What he meant was that the shock valving and damping are very good and very well matched to the springs, so the car does not wallow and it settles very quickly after bumps. This would mean that the ride very composed and not harsh or bouncy (rather than soft).

 

Mr.Duck: Your comments are invaluable! Many thanks!

I'd love to see how these would work with lightweight wheels/tires and some chassis stiffening....

 

d00df00d i am also learning a ton from your posts in your opinion should we put preload on our springs?

 

Jinsu, is there a way to get the valving that is more matched to the 9/6 settings?

 

ksport's valving is tageted for a wide range of springs rates so u can adjust the damping and deal in. I believe they do off customize valving service for extra charge but not sure how much.

 

I can't speak from experience, but I can tell you what I know from what I've read.

Preload will increase the amount that the springs push up on the car. Of course, that also means that it will increase how quickly and how hard they push the wheel down after you clear a bump or run over a ditch. Basically, it'd give you a bouncier ride but less lean. It would also wear out your shocks a little faster because it will make them move faster.

Apparently K-Sport reccommends no preload at all, if that's worth anything to you. Personally, I'd think the springs would be stiff enough as they are and there'd be no need for preload.

 

The existing valving is already matched to the springs. It's just matched in a way that requires high damping for the default rates. Honestly, you'll need high damping with stiff springs anyway. There's only so much smoothness you can get with 9/6 springs.

Basically, the valving is such that you can go with the default 9/6 springs and high damping for the best handling, or you can go with 7/5 springs and reduce the damping for a smoother ride. I think that's a pretty good setup, and certainly a steal for $740 shipped.

Valving the shocks specifically for the 9/6 springs rather than a range of spring rates would be a waste of time and money for most people. You'd end up with coilovers that'd cost a lot more because the development costs would be huge, and the benefit wouldn't even be noticed by almost everyone.

 

No preload on the springs Ducky.

 

Ok I have read through this thread but has anyone from NY have these coilovers on their vehicle. Just trying to get an idea on how they feel.

 

 

Thanks Mr.Duck for the pic!

Wei, do you have an update on the status of my order?

 

should be shipped already, I will get you a tracking soon. probably today or so.

 

for all Hawaii orders, Shipping is $90 more. Please send the shipping charge to jinsupower@gmail.com along with your order.

 

OK im FINALY ready to purchase. just wanna make sure. are u using UPS or USPS? basically i need to know if u will require my PO box or street address to ship. can u PM me your answer so i get it ASAP and can send money thanks!

-Brendan

 

We require physical address cause the coilovers will be too big for PO Box. When you order though the link, it will ask you for your shipping addres. For all HI orders, just paypal the extra shipping charge to the paypal address above ^

 

payment SENT! (from paypal1234@hotmail.com) thanks

-brendan

 

send me an email with your application and phone number!!!!!

 

I have the D2's (very SIMILAR) to the KSports, they were pretty rough at first, I have had them for on for about three weeks and about 900 miles on them and they feel much better now that the springs are starting to settle and the struts are breaking in.

Off topic... i just installed my Cattman Cat-Back today and it sounds great!!

 

hey jinsu....i oredered the suspension to ship to hawaii....i already made two payments for shipping and the suspension.....its actually under my girlfriends paypal account cause i didnt want to make one..... well my name is russell and my number is (808) 368-6767....give me a call and let me know how long its going to take...thanks, russell

 

the order is being processed. I will get you a tracking number when available.

 

Wei, I just called Ksport directly and got a tracking # from them. My coilovers were shipped out today actually.

They were unbelieveably helpful and nice to talk to on the phone!

 

good to hear that your are happy with our service.

 

Alright, I have a couple of post-install pics. I am still unable to post attachments, though, so I set up a Cardomain account. Most of the pics I have are too blurry, so I only posted the few clear ones. http://www.cardomain.com/memberpage/850151/1

 

that's one clean max! Nice job, the drop looks perfect!

 

Thanks, soon I'll have some gunmetal 18's too. I'll post more after I get the Stillen front fascia and rims.

 

for ppl that don't know, check out our new online store at www.jinsu-power.com
Nismotek, if you haven't ordered your rism yet then let me know what u interested in, i do carry alot wheels brands as well.

 

So, just to be sure I won't miss the boat- I can paypal the $740 on the 31st and be "in", right? This sounds like what I have been waiting for..

Only possible issue is that I have Koni yellows in there right now... I dont know if I still have the rubber top part that people are talking about...

Will I find out that I am missing something?

 

Sorry, I already ordered some GM Exel Ennio 18x8 w/ 245/40R18 Toyo Proxes 4's from Wheelmax.com. Hopefully they will be in by the middle of next week.

 

you can alwasy get the rubber top mount from the dealer if u dont' have it no more. But i would think think your koni should have them. And yes you are correct that you can be in when u pay on the 31th

 

You should be okay. I think only the 5th gen's need to re-use the rear upper mount. The fronts come preassembled.

 

Do you have a set for a 2004 Infinity G35C? I might know someone who's interested...I'll keep you posted on his decision if you have a set for his car.

 

Im getting super-stoked....

My deal is that my 2 front Koni yellows are blown, and I am heading back to the shop that got me them next week (thurs) to talk about my options - like if they can get them replaced for free. (Heard they had lifetime warranties??)

Now Im thinking I will just ask the guy to get the konis replaced, hand 'em over, and do the install on the coilovers. I guess I will be looking to sell the konis along with the Eibach springs. But until I deal with this I figure I should wait to order the COs.

BUT....

Jinsu, you can get wheels? I'd be interested finding out what the price of SSR-C's in 15x7, 15x7.5, 16x7 and 16x7.5 are, if you can get em.

 

I do have application for 03-up G35, they come with front and rear top mounts but no camber plates because there is either no more or it won't do anything to this particular application. Special pricng for G35 is $880shipped. (retails at $1400)

Spaniard, pm me for wheels along with size, offset, and bolt pattern. I will see what i can do.

 

FYI, the reason there are no camber plates for the G35 is that camber plates only work for MacPherson strut suspension, in which the strut is bolted directly to the part that the wheel is mounted to. Because of that, if you change the orientation of the strut, you change the orientation of the wheel. The G35 uses 4-wheel independent multilink suspension, in which the shocks are not attached to the wheel hubs.

Just wanted to share... I've been doing a lot of homework on this stuff.

 

thanks for d00df00d's technical input. i was looking for the right words but you said it!
