Hey guys. I'm a bit confused. This is my first time modifying suspension on a car and I wanted to get some opinions before I make my decision. I'm looking into 350z stock springs, 350z tein H techs, tein s techs, eibach pro kit. Which would you go with and why? I'd like to get rid of my fender gap and improve handling if possible while keeping a good ride quality. Thanks in advance!

 

coils /thread.

Its pretty near impossible to lose the fender gap, improve handling, and keep ride quality with springs. Youre going to need to upgrade the stock struts as well to accommodate lowering springs. If you dont you will end up with a sh!tty bouncy ride that is worthless unless the car is parked. At that point you're going to be ~$200-$300 in springs and another ~$600 in shocks. Thats almost $1,000 for a sub-par suspension upgrade. You should just save up and go with coilovers. You will be MUCH happier. You can go lower, the ride quality is eons better than even the best strut/spring combo, and you will definitely notice an improvement in handling.

 

^There is no reason that a coilover would be more comfortable than a good spring/strut combo setup. Also many times a good spring/strut combo will greatly outperform the vast majority of coilovers out there. Springs and strut combos are in no way inferior to coilovers, and are often times even superior other than the fact that you can't adjust the ride height.

 

Thank you for your response that helped a lot! I do like the adjustability of coilovers but they're just so expensive and I'd probably have to get a camber kit as well right? Which coilovers would you suggest?

 

I do like that coilovers are adjustable. I haven't heard that springs can outperform coilovers, which setup would do that, this has me interested. I would enjoy maximum performance and comfort.

 

I got springs and a fully suspension setup with struts and my ride quality is no where near rough or bouncy. Most G's ask if I'm on coils but no. It's really up to you but Goodluck and be happy modding

 

When you consider the cost of springs and quality shocks you've very close to what a good set of BC coilovers would cost. Before you jump on the suspension mod wagon consider the cost of a complete camber kit which is needed if you lower your G35. SPL camber kits are very close to $1K installed but that's the only way you can lower your car and not eat tires! If you can't afford $2500 to lower your car leave it alone!

But would I still need a camber kit if I only wanted to lower about 2"-3"?

 

I used 350z eibach sportlines and they ended up lowering the car about 2.2"F and 2.0"R. The camber in the front is alright, but in the rear it is pretty bad. I desperately need a rear camber kit. The fronts can probably be corrected with the stock adjustment. From what I've seen, these are about the lowest drop of a spring you can get. And they're all of about $250 for a set. I'm using my stock struts, and though they will wear out faster because they aren't in the idle range of motion, I'm happy with the ride quality vs. tightened handling!

 

why do you want them to be adjustable?

If you want best performance and comfort, pay money for good stuff. You basically want shocks that are very digressive, that is with forces that ramp quickly at low speeds, but drops off dramatically at high speeds. To get this, go with reputable companies, like kw/koni/bilstein/ast/ohlin/jrz/moton, and stay away from japanese/taiwanese/chinese/korean stuff like bc racing.

When you are talking about lowering in the 2-3" range, you get to the point where you are probably really hurting the performance of your car. If you want to drop that car and improve the handling of your car, prepare to pay bank. The stock car doesn't have all that much bump travel and with that big of a drop, you need some super beefy springs and super beefy bumpstops to prevent bottoming out and probably custom valved shocks, since i doubt out of box shocks have valving that strong. You would also need roll center adjusters to get your roll center back from under ground in adition to camber arm in front and camber and toe arm in rears.

also, getting bling bling wheels will aggravate all these problems. for handling, and to be able to drop your car more, consider getting ultralight wheels, or even better, downsizing your wheels to 17" and getting ultralight.

Also, because the car is modified double a arm, the fronts have 0 camber adjustability from factory.

Also PLEASE EVERYONE, we have 4 shocks, and no struts.

 

ehhh idk about that. I agree that with a quality set of springs and shocks you can achieve great performance and ride quality, but I have never ever seen at a track day (and I attend many) a spring/shock combination that offers what you can achieve with a good quality coilover setup. And i'm not talking BC or Megan... And realistically if you're going to spend the cash for the best of the best spring/shocks then why not just spend the money on coilovers anyway and get the full adjustability too?

I just dont think its a fair fight. But I like to be proven wrong.

I think the first thing that needs to be figured out is what the OP intends on doing with the car to begin with and what kind of budget he has.

 

You dropped 2"+ and front camber was still fine?
