Slamming your car. Does it affect steering/steering parts?

K so I slammed my car and i notice this knocking/clicking sound every time i turn the wheel, when i go over small bumps, and sometimes when i shift agressively from 1st to 2nd. Its as if the there's play in the steering/steering parts or something is loose. This only started happening after i slammed my car. Here is some pictures of the slam and stock comparison.

Tein Basics adjusted to almost max (2 treads)

When I bought the Tein Basics from the shop they set it to so called Tein factory specs, telling me to leave at this height before i adjust it some more because I have to break in the springs first. Dropped at this height it didn't have any of that knocking sound when i steer or go over bumps. When I went ahead and loosened the spring seats the Tein factory spec was adjusted to 6 treads from the bottom vs my slam which i adjusted to 2 treads from the bottom.

So before you reply to the post and get off topic like i know some of you will, the MAIN QUESTION is:

Does slamming your car that low (like in the picture where i adjusted the Tein Basics to 2 treads) affect steering or steering parts?

I also noticed that the handling was better when it was slightly higher (Tein factory spec) and when i slammed it the steering became more sensitive to bumps and the car would turn where ever the bump was, prolly cuz of loss of wheel travel.

Who ever came up with that use the word 'slam'. God just say lowered. It just sounds so wanna be ricey/gangsta when you say slammed, esspecially that many times in a row.

As for your question, it could be that now you have less clearence in your wheel well, you might be rubbing/brushing against something.

keep in mind that nissan engineered all the suspension parts, as well as the suspension geometry, to work best at stock heights. lowering your car by 1" or more, will affect the suspension geometry of the car, and will most likely have a negative effect on steering/handling. i remember someone on the v board did a nice CAD drawing, showing how a drop of 1" or more will affect the geometry. it is a good read and i suggest you read it.

so overall, lowering most car for more than 1" will make the handling worse than stock, unless you change the all the suspension parts to reflect the new changes (very time consuming and costly). there is a reason why the nismo shocks and springs kit only drops 0.9" or something like that. depending on what you want to do with your car - if you race, then dont lower by a lot (or just dont lower at all); if you like to look nice, then by all means, lower it as much as you can.

No there is not rubbing. Also how much times I used the word slam has nothing to do with how "lowering" my car and how it affects my steering and steering components. I basically use the word "slam" to emphasize the excesive drop.

Yeah i read and saw that CAD drawing about suspension geometry and am aware of how lowering the car too much affects handling because i've experienced it first hand dropping the car this low. I have way more body roll now than I did when I had stock suspension. It sucks but you gotta pay to play but right now because of this steering thing going on I don't know if I wanna pay anymore :(

I know what the physics say but I drove a car with ground controls and koni yellows today and it was Awesome! Of course the ride was horible but that lower center of gravity really makes it corner like a raped ape.

I know I want them.... I'd really like those teins too!!

my car is lower than yours and it makes no noises.


if you used your stock strut mounts (not sure if tein has a b15 application), but anyways, check and see if your thrust bearing got crushed or is even still there. they are plastic and tend to wear out quickly. if this is the problem, buy a pair of b13 thrust bearings which are made of metal.

okay now im starting hear a sqeaky sound everytime i go over some bumps on my passenger side. i'm raising it this sunday.

it sucks i can't have my sentra slammed and still have good handling and not harm my steering parts, sentras at disadvantaged in appearance because of this. its fair honda and subaru can look friggen awesome with just a 2 inch drop. however when we do a two inch drop everybody is like whoa dude thats too low. we will forever look like monster trucks if we don't want to compromise functionability of our suspension and handling. qft.

but i rather have my car running properly and handling well if it means looking nearly stock so be it.

Dude I wouldn't compare our cars to Honda's. Just for the fact that we handle way better than most honda models. And most people with honda's lower their car 2" just for looks. I lowered mine 1.5 back, 1.7 front and it looks good. For example my car:

this exactly how i was gonna set it to on sunday. cuz when i had it at tein specs, basically like how you have it in the picture. it handled really awesome. i was hanging turns like magic but you know all my friends are like "ho dude slam em! looks mean" i live in hawaii so i grew up and lived seeing dropping your car till there's no clearance between tire and fender was the way to go. diggin your rims yo what are they.

I remember reading something about how lowering a Sentra too much can kill axles & CV joints quickly, but I could be wrong. That clicking sound could be a CV joint or axle going bad... ( 'o')!!

im only lowered an 1.25 inches roughly and recently started hearing the same wierd noised in the d/s front supsension it only happens at slow speeds and when turning the wheels at a stop. and when you first let teh clutch out to start driving. it is strange i have checked all the bolts all the mounting checked for leaky struts the whole nine.

i am lowered on voglants 40mm sport springs and koni yellows. have been for ayear now with no problems. i might have to check into the b13 thrust bearings though sounds like a sound investment this would also give me a chance to make sure my oem strut housing hasnt cracked from the koni inserts

im tired of people referring me to this thread because i've read it many times, and no it doesnt say anything about how it can fck up your steering parts/components.

yeah i was messaging a few suspension junkies and they were saying how lowering your car too much puts more stress on your steering parts, cv boots, and tie rod and what not.

well i raised my car today and that click/knock sound went away. i do still feel/hear it when i go over a really steep small bump. those bumps with a sudden drop off that shakes up your car abruptly. but glad i raised it cuz it handles like magic now. ill post pics of the lift later.
