First of all, sorry for asking something many of you think is simple. I'm not familiar with suspension setups but I'm willing to learn. I did some searching around the forums, and found some pretty good information but I just wanted to double check before I went ahead and potentially screw something up.

I'm looking for a setup that will give me a decent drop and close the wheel gap on my coupe. Not looking to get slammed at all. I will be using OEM 18" wheels. I'm looking into either the Eibach Pro Kit or Sportline, or the Tien S-Tech. Not going for coils at the moment. Some things I came across my research are the need for additional struts/shocks and camber kits. Are they actually necessary? I saw some people ran Eibach springs without camber kits with no problems but also heard that they are needed. With the springs listed above, would I need them? Also would they require shocks like Tokico Blues or can I just slap the springs on my OEM ones without needing anything else?

Thanks for your help. Looking for someone to educate a nub. lol

 

This guy use aftermarket springs, and 350z suspension. Hope this somewhat helps.

Yeah I did see that thread. It gave me a really good idea on how it will look. I'm just looking to see what people with aftermarket shocks/struts say. Thanks!

 

You missed out some vital information like is it a coupe or a sedan?

Any future plans as far as wheels and suspension go?

If you have a coupe and just want a mild drop while using your oem struts comfortable and not use a camber kit? Your best bet is probably getting oem Z springs.
To my knowledge it'll give you 0.5" of a drop which is pretty conservative and cost efficient.

As far as camber kits go. It really depends on the car.
Some can get away with it others cant.

 

Good rule of thumb is that anything 0.8" or more should require a camber kit.

But for any drop, I would get a rear camber kit at the very least.

That way you can just do it right the first time

 

For a mild drop like that the front camber should just be fine (which is good because decent adjustable upper control arms aren't cheap). The rear camber may or may not be to your liking, there's a good chance it'll pick up a degree or two of negative camber, so if you want it to stay OEM get adjustable rear camber arms. The biggest thing to worry about is the Toe, which will require "toe bolts" in the rear that give more adjustability. The front toe is almost infinitely adjustable from the factory so no worries there.

Above all, get an alignment as soon as possible after doing it (ideally let it sit for a week and let the springs settle, driving it very little so you don't destroy tires, but that's unlikely unless you've got another car to drive).

On the off chance you're unfamiliar with camber vs. toe the easiest way to explain it is that camber is the vertical orientation of the wheel - is it straight upright or is it leaning into the body at the top (negative camber). Camber will cause uneven wear as the inside of the tire is touching the ground and the outside is not. Toe is the wheel's rotational orientation in relation to the ground. Toe in is basically like duck walking, and toe out is like walking pigeon toed. Either of this will absolutely destroy your tires. The wheel wants to rotate smoothly and if your toe is off it's unable to do so, the tire basically skips across the ground instead of rolling. If your toe is bad enough it becomes a safety concern as well.

I know that's all pretty much extraneous information but it's good information to have, you want to know the side effects of altering the suspension before you do so.

 

The need to replace your shocks depends on what condition they're in. If they're OE shocks and you have high mileage, replace em. Cheaper to do the springs/shocks/camber kit at the same time. Any time you lower our cars you'll not only need a complete camber kit but someone that knows how to align/adjust them to OE specs. SPLs offer the most adjust ability. If you're just looking to close the gap I'd go with Tein H-Techs and you could do the "Spring Mount" mod if you want it lower in the back end another 1/2"....Search. Everyone has an opinion about the need for a camber kit, unless you own a tire store you're better off with it!

Thanks for all of the great responses. I've learned a lot!

 

look into tanabe nf210.theyre awesome
