Lowering a 2002?

First off, i'm new here, please don't bash me. I just bought a 2002 G20 with the sport package. I've installed a brushed aluminum dash kit and Magnaflow muffler. I want to lower it, the car needs it bad. I'm looking for a set of progressive rate springs to lower it about 1"-1.5". I heard the Eibach prokits are to harsh. Did hear that that H&R springs where a nice ride, but when I go to their website, thay don't even have a listing for Infiniti. Any suggestions would be appreciated. This seems like a good forum. By the way if it matters I work for Infiniti, if anybody needs any warranty questions answered or technical questions.

ask luke at digitalracer.com

He's the g20 guru

Welcome, and dont be scared of getting bashed here! we're a tight knit group and dont bash anyone! ;)


If you want to lower your car and get decent riding, get the Eibachs. The H&R were offered for the Nissan Primera (G20's twin in other countries), but the H&R are a very harsh ride!!

Also stay away from Intrax springs with stock shocks.... PROBLEMS!!


If you want the best ride possible... get the Tein type NA kit. its $1100 and includes lower springs and struts designed specifically to work with each other. It is a very smooth (close to stock) ride on the soft settings (the struts are 16 way adjustable in stiffness).


By getting only lower springs with your stock struts, you will eventually blow out the struts... ie.. headaches!!

If you get the Tein, you wont be sorry. :)

[email protected] can get them for you. not sure if they're listed on their website www.digitalracer.com

good luck.. and dont be afraid to ask questions here! :toothless

Thanks guys!!! Great forum

nah, i aint no guru :lol2: but if you got quetsions, ask away and many of us will help you out.
as for the TEINs, just like what b00gie said, they are pretty much the suspension part to get for street use...near damn perfection! :D and i do have them listed in my website hehe.

thanks guys for recommending me to others :flash:

I have H&R currently on stock shock and they are a damn rough ride but I kinda like it....shocks are starting to go now so need to upgrade them...

Luke, what was the name of those Swedish coilovers? B&H (B&G?)/ Why not recommend those? And is there an aplication for P10? (Sweden is pretty close to Estonia).

well, just like i dont recommend my super duper JIC coilovers (i wnat to be the only one that has it...haha JK) most coilovers do not have a comfortable ride. Real coilovers are designed for track use and it's very uncomfy (unless you are like me and like the ride VERY stiff) on the road.
the TEINs on the other hand, is not a coilover, but springs and shocks set up. the shocks have 3 slots to adjust the height and also 16way adjustable dampening valves to stiffen/ease up the ride quality. Since I had the TEINs on for a while, like many others, they come very highly recommended for the street and daily driving. However, if you are like me and tackles autocross or road race events, i would HIGHLY recommend the JIC-Magic coilovers, you can pick you own spring rate (i am using 10kg/8kg), piston and valves.

One reason that no body has recommended the B&G is because no one here owns them yet...


We are waiting for Dprotech to install his in his P11. Once they are in, he and Jason (G20.net) can compare each others cars first hand... ;)

OK, fair enough

Still, could someone give me an URL of B&G?

thaa, do you have any information about them?

Hey guys, I am new to the forum. Been reading lots of postings to keep me aloft. One thing I do not pick up from the readings: Of all the great mods suggested, who would normally perform the works for these? I am thinking of lowering my 02 G20 equiping the TIEN Type NA Suspension, but who would do the work? Can I do it myself with proper instructions? 1PNYBOY, perhaps you can help answer some of my warranty questions.

Many thanks.......:D :D

P.S. I am annoyed by constant scratches to my car, is there an alarm system that notifies me when my car is in contact with others? Not necessary motion dectector. Luke, maybe you can help? Here is a pic of my baby....

Nice choice in color. Limited edition Maui Blue, only made it for a month. As for your warranty, should be okay, unless the people at your local dealer are assholes. Some are, but most aren't.

Very nice colour!

Yes, you can do most of the work yourself, but better find some other enthusiast in your area to guide you through you first steps. And, as most of guys will tell you, the firs mod should really be a good FSM.

Good luck

installation on suspension parts is quite ez...basically just nuts and bolts..the front ones require some muscle and patience but the rear is VERY ez.
as for scratches...do what i do, park in a very isolate place with about 20 feet away from cars from all direction! hehe :D

muscle is right!! the front suspension is a pain in the !@#!$!

actually, installing the front ones aren't a pain in the ass if you read the picture in the instructions correctly. it went in correctly the first time for me. :D

any goof with some good metric sockets can do this job. I didnt even use a torque wrench and proud of it. hehe. :p the biggest painin the ass is using the spring compressor. also never use an impact wrench on these TEIN kits.

I really cant agree with you Ken.

The front suspension is a real pain to work with. Yes getting the strut in is no problem.. The problem comes when you need to put the bolts back through the upper link arms. Its a pain to line up and it doesnt want to budge.

Woow! You real amateur mechanics! Thanks for the tips!
Luke, I start to do the same thing with every new car owner would do, park real real far away. :)

The only problem I had with the front suspenion was lifting it and getting the bolts in. Its tough to do by yourself but as for lining up it was no problem. Just make sure both front wheels are off the ground, otherwise the front swaybar will deflect the suspension. I know because I did that the first time.

hmm.... :huh:

DOH!! :buck


I did mine one wheel at a time, you live and you learn I guess. I could have wrestled an alligator easier than than I did the link arms, lol....

really? do the front 2 at the same time huh? damn, i just did it one by one and it was freaking tough to put in the front JIC...thanks for the tip Jas

Hehe, the first time I did my Teins I was doing one side at a time. Well the front was SO hard to line up I almost started crying. :( That is until I realized that the stupid swaybar was causing all my problems. I jacked up the other front wheel and it was no problem after that.

Yeah, after doing one front side, by the second I was exhausted and literally covered in sweat. I noticed the sway bar was causing some problems, so i loosened it a bit which helped.

...but now I know what to do next time ;)

Guys, now that you have convinced me to go with the Tien Type NA Suspension system. Could anyone describe the differences in performance and handling of the existing (2002 G20) stock suspension with that of the replacement Tien suspension system?
Will it be better at corners? or harsher? Frankly, I am satisfied with the stock suspension in terms of performance and handling, but I would like to lower it as well. Can someone please advice?

thanks.....

With the teins, you car will handle better. better shocks and springs provides more stablity during cornering and eliminates a good amount of bodyroll. the ride is stiffer than factory set up, this is the tradeoff of having better suspension (sat in a M3 lately?) however, because of the dampening adjustablity in the Teins, the ride is far from uncomfortable.

Luke,

Thanks for your reply. I did not want to install a $1100 suspension system that performs worst than the current stock.

So there is always a trade-off? Cool. I can live with the harder ride. Not planning on doing long distance drive anyway.

Cheers.

Am I the only one here that has a Ground Control kit for the P11 (www.ground-control.com)? I have it with the Koni shocks and it kicks ass also! The ride can be tuned to be quite close to stock. You can also really dump the car if you're into that. The handling improvement from stock is amazing, it eliminates brake dive and axle hop.
The price (GC/Koni) is similar to the TEIN setup but the Koni shocks can be rebuilt to different specs if you want. However, the Konis are not externally adjustable.
Another advantage of the GC coilovers is that you can use it with different shocks if you change your mind later, for example GABs are externally adjustable. Also, you can easily swap out the GC springs for different rates or lengths.

The only gripe I have about the TEIN setup is the low spring rates. Then again I race my car at auto-x and sometimes an actual track. The GC's would be better if you do some casual motorsports as you can choose your rates. I've actually got my eye on that JIC Magic setup now. Damn you Luke!!! :D:D

If you just plan on lowering your car and driving on the street the TEIN is probably the best setup becuse it's a 'set it and forget it' kind of setup. If you're a real tweaker then get the GC's because the TEINS are a bitch to hieght adjust.

Yes, the Ground Controls can be height adjusted without taking apart the suspension. If you do shows or races you can dump your car real low and then bring it back up for street driving in a few minutes.
Sometime I hope to compare the TEIN with the GC, it should be interesting! I suspect the TEIN has a slightly better ride over big bumps because of its more progressively wound springs.

yah, I use the NA's myself on my G. got it direct from TEIN, about $1100-$1150 with priority air shipment. got it within 5 days. :D

its pretty easy to install the teins. all you need is a spring compressor and some ratchet/sockets. comes with excellent illustration instructions and Im japanese so even easier for me. hekkeekekeek..jack stands do help, and use your factory jack under your lower arms. would suck if your drive shaft came apart. hehehe. :D took me about 8 hours to do by myself including breakfast and lunch break.

Don't forget the TEIN has a shortened shock body too.

so you can't adjust the TEINs with out removing? completely removing?

and, how m uch do psring compressors cost...don't remember ever seeing those at the store.

THe GCs are just sleeve and custom eibach springs...using factory shock housing, you cant compare it to the TEINs...personally, i think the whole GC thing isnt really up to par...i have used it before so this is coming from experience...
anyway, if you do do real track racing (more than just once a year) JIC is the way to go....the spring rate is ultra stiff, 10kg/8kg, 36mm piston shaft and super duper shock valves...hehe, it's really stiff but it does wonders on the track and, this might sound weird, but it's not relaly uncomfortable on the street either, you feel the road but it doesnt crack your back. hiiiighly recommended if you do lots of track time.

dre, you cannot adjust the height without removing/disassembling them :(

you can adjust the damping rate w/ the click tool on the top of each strut.


I got my spring compressor at www.autobarn.com for $40. Its a manual one which is a pain, but the professional ones are hundreds and hundreds of dollars...

spring compressors are about $40 for the pair. dont needs anything special.

yep, short shockbody but wider. TEIN's usually have 110% of stock stroke length...so yah, if you set your damping right, thing can be lowered quite a bit with decent ride and excellent handling. I say decent with discretion...as I too like stiff sus on my cars. I cant stand stock sus on these sedans.... yuck. gets me sick. :D

It wouldn't be very smart to use stock shocks with Ground Controls, it's better to use aftermarket ones. The Ground Control kit includes new aluminum upper mounts (for the front) and lower mounts as well as shock collars.
The main advantage with GCs is that you can use it with all different kinds of struts and springs to tune it for maximum flexibility. You can make it very stocklike or really hardcore with double adjustable shocks and super stiff springs.
The basic GC kit is about $500 with their urethane bump stops. A basic set of shocks is another $400-$800 on top of that.

TEINs....$1100 shipped from me!!!!! the BEST!

luke's da man!!!

Just got my eibach's from luke. Look and ride great!!!!!!!! Got em' quick too, even though they where on backorder. Thanks Luke. Digitalracer rules!!!

YAAAH!!! Luke is the BEST man!!!!!! so damn good looking too!!!!!
hahahahah......

thanks for all the good comments...trying my best to help fellow G20/Primera peeps :D

Do any of you guys know how much you can lower your car with the GCs? I've read/heard 0-4inches in height adjustibility. Is that the case for the G20s???. What about the Teins? What's the height range on those? And also, can you adjust the chamber on both of these??? I'm kinda afraid to put in my Eibachs, cuz I read it only lowers 1 inch max or something. I've got 18's waiting to be put on, soon as I figure out which suspension set-up to go with. Personally I'm leaning a little more towards the lowered look over the ride quality...maybe like 55% looks and 45% ride...any recommendations??? Thanks!:D

hey...try www.g20.net instead of here...this is one old ass thread you just posted on...

Thanks Tony for the link...u located in SoCal right? Might see you on the road sometime...peace!
