Lowering springs question

A great resource for Nissan Sentra, Infiniti G20, 200sx, Pulsar, NX1600, NX2000, Tsuru, Primera and Sunny owners.

you would only get a bouncy ride if you blow your struts.

The ride obviosly would be stiffer because of increased spring rate and less damper travel. I would call it more of a "firm" ride, and you will feel the bumps more. Ive had my pro kit for about 2 years and my struts were fine. Sprotlines are a more agressive drop so there is even more stress on your shocks and struts. Stock struts arent made to handel the extra load on them, but if you drive it reasonably and keep out of pot holes you should be fine.

On an SE-R, Sportlines *might* be doable long term, as one member's car proves. On a 2.0S, I'd stick to the Pro Kit.

i have the sportlines and i love them. im about to sell my car, do you want mine? the ride is noticeably different, a little bouncy on bumps and dips which i love for highway driving. i've had them over a year with no problems.

So you are saying that the SE-R has different/better SHOCKS in addition to different SPRINGS vs. the other Sentra models as-delivered by Nissan? Can anyone confirm or refute this?

I'm not saying that it won't be "fine." I'm just asking if the SE-R will really be more "fine" than the other Sentra models, as was suggested above.

Correct. In addition to stiffer springs, SE-Rs and Spec Vs come with a slightly stiffer damper designed for the stiffer springs.

This was certainly true in B15s. Cross referencing part numbers would verify for B16s, but I don't see any reason why they wouldn't adjust for the stiffer springs on B16 SE-Rs as well.

No one has brought this up yet so I thought I'd mention it.

When you shorten your springs the stock struts compress a bit which takes away from the over all travel of the strut. This means that in a hard cornering situation your strut will bottom out and you can see some over steer (or under, I forget which one is for which drive wheels).

Realistically you aren't gunna be driving in hard cornering situations all the time so you probably won't notice the difference. Especially since you could end up spending alot of money on sport struts.

Just something to keep in mind.

Eh, not exactly. You won't magically bottom out any more often in hard cornering. Remember, the shorter spring is, most of the time, also stiffer, thereby making it harder to compress. So while there is less suspension travel, the aftermarket suspension will also tend to travel less in the same conditions. It's not a matter of bottoming out more often so much as the constant partial-compression and more force put on the struts that wears them out faster.

Also, over/understeer isn't a matter of drive wheels, it's the relationship between the front and rear of the car. Generally, FWD cars will naturally understeer. However, most aftermarket springs are designed to make the change in rear end stiffness more than the change in front end stiffness, thereby making it easier to bring around the rear, thus combating this innate understeer tendency.

I didn't think about the springs being stiffer preventing bottoming out.

I was just parroting something I read about a project car and that was the reasoning they gave for upgrading to adjustable struts.

although that was 200sx b14 being discussed

Well I cant do anything to the car right now cause im having problems with it and I have taken it to Nissan twice and they still haven't fixed the problem. I dont want them to blame it on the springs or anything but after the car is fixed and if you still have the spring I might buy them off you. You have a sick ride by the way

Any comments on the H&R Sport Springs? Does anyone have any information re: spring rates of the Eibach Pro-Kit vs. Sportline vs. H&R?

might be different on B16s, but on the B15 chassis sportlines are pretty close to the stock spring rate. shouldnt have much faster wear than with stock springs, maybe a stiffer ride from having less shock travel.
