Not sure if there is already a thread on this, if there is sorry. Figured if anyone wanted to share their experience with lowering their car with Eibach's Pro Kit and the resulting ride quality.

I came from the SV Sport/Tech so had the sport suspension already. Going to the Pro Kit isn't a huge change but it is different and noticeable. Obviously the kit makes handling incredible and DEFINITELY makes the car look nicer. I'm borderline though on whether I still like the smoothness of the ride.

For me it generally seems the same unless you're on one of those real crappy-looking pothole-pockmarked roads in which case you're going to definitely feel the car is lowered. I drove on a few roads that has spots patched on them and could definitely feel the roughness of the road more than I was used to.

If I had to give an overall recommendation to someone looking at getting these, but don't want to kill the ride quality, I'd say this. If you have the premium/normal package and like the ride, I probably wouldn't get these unless you're serious about wanting the dropped look/handling. Coming from the sport package it isn't so bad, and you probably wouldn't notice it as much.

Overall : I recommend it unless you have this car as your family car. The extra jostling probably won't be appreciated by the passengers. Oh and lower the PSI on your tires to 32-33 if it isn't already, this helps a ton.

 

I have a 2010 Sport, Im waiting till spring to see if I can get these, I really hate the wheel gap.

 

+1 danielevans83. I have the eibach pro kit and i must say its very worthwhile. The car looks and handles noticeably better. My only gripe is that I now get pwned by speedbumps...I usually bottom out on the really big ones. And I almost always bottom out with other people in the car over speed bumps...like you said probably not good for family hauling. Otherwise a good upgrade.

 

I have them on mine and Daniel Evans is defnitely correct, you will definitely notice the impact on ride quailty when you're on those rough roads ( should mention the car has 180k and I have stock shocks). However, the handling and look of the car has drastically improved and I am extremely satisfied with it. The car is a LOT more flat and the wheels definitely fill in the wheel-well more. Id say its worth the buy if you are a person who can get use to a rough ride, like me.

Tires also make the ride quality better/worse. I had worn tires when I first put on the springs and I felt every single bump in the road, but when I slapped on some new tires it was a lot smoother.

 

Keeping the tires below 34 psi should help and yeah tires can change everything. This is making me consider 19s now with thicker tires instead of 20s

 

i was thinking about getting these but i live in ny and these roads are bad so i dont wanna risk the undercarriage

 

Yo dj Dave, so many people have these springs and live in NYC, you'll be fine dont worry about it.

 

how are u bottoming out on just a 1 inch drop? that doesn't sound right. the springs can't be that weak.

 

This is a perfect post.

I test drove the 2010 sport package and loved the ride but ended up buying the premium for the sunroof and other features. On my drive home from the dealer I was really disappointed because compared to the sport i thought i was driving a Oldsmobile. Over the course of 4 weeks I really started to enjoy the smoothness of the ride but hated the wheel gap. On my first test drive after the spring install i was like "Wow, the ride is very harsh". Over the last few months I've gotten used to it but still miss the smooth ride. Knowing what i know now I might have opted for so 20's to fill the gap and not sacrifice as much of a ride quality. Now I want to add some 20's but really afraid it will be too harsh of a ride...

I sometimes bottom out over speed bumps and cant image what the car looks like with 4 people in it.

 

yea but most of the time i roll with 3 people in my car and this weather were having is crazy

 

This is exactly where I'm at now...I'm gonna try today lowering my PSI to 32 and see how that helps. I think this definitely decided for me to get 19's with a thicker tire...my last car had low profile tires and my girlfriend didn't even want to ride in it because it slamming around made her sick.

Wonder if some upgraded shocks would change anything here. I know I won't get the ride quality I had back unless I take the Eibach's off, but anything I can do to get it closer to where it was I'm willing to try.

 

I was in the same position as you but as the month has gone by ive gotten use to it. i was actually up to a point of just taking them off but now there ok i just hate it when i go over potholes and feel horrible but im switching to 19" and hopefully it wont get as bad again. And i ride with 5 people some times and ive never bottomed out. mayb a little scrape underneath from getting in and out of gas stations but never bottom out and i live in pothole city Manhattan

 

You going 245/40/19 on the tires or sticking with 35 series? I'm leaning towards 40 if it means I can have a softer ride and more of a sidewall to protect the rims from bending.

 

na im going 245/40/19 on the G37 wheels

 

Nice. If I can find a near-new set of the stock 19's I'll get some new all-weather 245/40/19 tires and sell the 18's. Tired of swapping crap on and off 2 times a year.

 

GL ive been trying to find some and i havent had any luck

 

wow everyone was saying how nice eibach was becuase they feel so much like stock...but it sounds like it's a lot worse.

 

Well, one thing to note is I'm still riding on the stock 18's with the original tires that don't seem to get good reviews for ride quality. Can't speak for those who got Eibach's and have aftermarket wheels.

Also, it's not like terrible or anything. Just definitely a difference that is noticeable, unless you're used to driving on large rims or having a dropped car. I'm sure to most people who came from another car that was dropped or with big rims wouldn't think the ride the Eibach's give is rough. I'm just offering my opinion on comparing the stock Sport springs to the Eibach's.

 

Good question, I wish I knew the answer But it is more than 1 inch, for me its about 1.5 all around. And with a couple extra hundreds lbs in the car hauling people, makes sense to bottom out on speed bumps.

 

I lowered the PSI in my tires from 38 to 32 today and I must say the ride is way less harsh and I barely noticed I had the springs on today. Granted that probably won't help with mileage or dented rims but maybe I'll end up at 34-35 to compromise. For now I'm going to leave it at 32 for a bit and see how it feels, definitely not as "bouncy" as the 38. I'm much happier with the Eibach's now.

 

Why would you inflate your tires to that high of amount in the first place? I assume you still have the stock tires/wheels on from your pics, the normal PSI required is 33 all the way around so why go so high??

Just asking.

 

Over the weekend i switched over to the G37 19" and they feel alot better and smoother with the eibach.. could be that its a different tire but i feel it real confortable

 

I was seeing .5 - 1 mpg improvement over 32 PSI and also wanted the stiffer sidewall to protect from potholes. When they salt and plow around here they wreck the roads in the process so it's kind of like driving on a mine field.


That's also really encouraging. The RS-AS tires seem to just suck in general so now you got me looking forward to Spring when I put shoes on her. Where'd you pick up G37 rims if you don't mind me asking?

 

post pic of the rims on ur car

 

I got them from a member on the other org and the good thing is that they where plasti diped already so saved me some time even though when I was installing them I peeled some of it off so waiting fo the wesrher to get better to touch it up

Sup kmoney mayb tmrw ill take a quick pick even though the car is dirty

 

heres a quick pic

 

Sick.

 

Stiffer sidewall will not protect your rims and tires from impact. The sidewalls on your tires are so stiff that they're not forgiving anymore.

During impact your tire can develop a bubble and therefore it needs to be replaced.

 

I like the pro kit alot.I took about 2 weeks to fully settle and now it looks like a even drop.It has been about 2 months now and i need to get the dealer to alighn it before the tires start to wear.Only complaint i have would be the front is kinda like a boat with a lil bouncing over minor humps in the road. the back is perfect but the front has a lil soft seesaw action going.I hear a lil creek sound when I exit the car and will need to grease the left rear area.It sounds like i weigh 350lbs when i exit and you the creek/squeak sound. lol.

 

Oh, I see. I figured a stiffer sidewall meant less buckling and therfore more protection. Glad I dropped the PSI anyway then. So far with 32 PSI I am loving the ride on the Eibach's, they're not bad at all anymore. I still need an alignment in a week or so.

 

why do u need an alignment ive had them for about 6 months now and i dont need it even though its recomended and i will get it but y the rush

 

I was planning on doing it before I got the springs on due to everyone recommending it cause of potential uneven tire wear. I'm about to put the stock 19's on my car anyway so I figured I'll wait until that happens and do a balance/alignment all at the same time.

What's more come to my attention is that I feel the wheel shaking back and forth when I apply the brakes lightly. Definitely didn't do that before, I have to assume something with the tires or alignment is the problem. I'll jack up my car and make sure my lugs are all tight to eliminate that possibility.

 

could b a rim that need balancing possibly one of the front ones

 

Reading this thread I was thinking It would be interesting to get some demographics from the people offering information about the ride quality..

I think my opinion comes from being older than the normal Maxima owner and the vehicle I came from (a Ford truck). Primarily my buying decision was because the Maxima because it LOOKED GREAT, had nice performance and was a really good value compared to other options so I guess that's why I think the Eibach rides a little harsh over some other people.

Its not horrible by any means but with some 20's I think it might be more than i want..

 

I just returned from the Nissan dealer after having the Eibach's installed, and even the 80-year-old dealer/owner was raving about how great my Maxima looks with the new springs.

I went conservative on wheels and tires, choosing the exact same 245/40-19 that comes on the Sport editon. I did, however, go with a different wheel: The RPM R505 Mesh with polished dish and the car looks phenomenal!

I too was very nervous about how the ride would be affected by the new springs, because the Maxima in stock form offers such a smooth ride.

That said, I am ASTONISHED at how much BETTER the car rides! The ride is even smoother than stock. Bumps and road deviations are dampened and isolated much better by the Eibach's than the stock springs. The bumps and thuds don't make it into the cabin nearly as much as the stock springs. The car is still a very smooth ride. The tires, BFG KDW 2's are a bit noisy, but the Eibach's have actually improved both handling and overall ride quality.

I probably went a little too aggressive on the tires, but damn, they offer some stomach-churning grip. I have a 270 degree diminishing spiral entrance ramp that I've been driving for the last 10 years on my way to work. It's tricky, because it tightens towards the end. With stock tires, I was maxing out at around 50ish, while my stock 2008 Miata can take it at over 60 mph. With the new BFG KDW 2's, I'm easily over 60 mph all the way through, with zero tire squeal.

It's amazing how such a minor tweak has so radically improved both handling AND ride quality. And the appearance, has gone from "good", to "bad ***" (directly quoting the 80 yo Nissan dealer!)

To those having reservations about the Eibach's: They are completely unfounded. You'll be very pleased with the Eibach's IF you stay conservative on the wheels/tires. I'd suggest a high-performance summer or all-season, like a Goodyear Eagle GT or event he OEM RSA's, etc, and stay away from the Ultra Performance, 35 sidewall, 20 inch variety.

The car looks GREAT with 19's.

Considering the fact I'm over 40, and have no interest in a go-cart hard suspension, this setup is a perfect balance between smooth most of the time, and aggressive when I need it. Michigan roads are perhaps the most unforgiving in the world, and even with the springs and wheels, my Maxima is waaay smoother than the Miata.

Go for it. You won't be disappointed.

 

Anybody have the kit on a premium, but with OEM sport 19s and Potenzas?

 

Months later I'm still with no alignment since my camber looks fine, ride quality is amazing on the stock 19s. Nobody can tell its on a sport suspension, the ride coasts silently and smooth almost better than stock. Love the look it gives too, real mean. Looks like my biggest mistake after switching to them was having the PSI too high on my tires. Yes it is noticeable going directly from stock to Eibach's but it's months later and I can't tell at all...

 

you just put me back on-board for this mod

 

How hard are these to install?

 

All the rear requires is a jack. The front you will need spring compressors. I would also recommend not attempting this yourself unless you have air tools.
