Z33 Suspension mods... any advice?

Okay, so it looks like I’ve now sold off the rest of my mods from my EP3 Civic, which means I have the cashflow to get the suspension on my Z taken care of!

I’m trying to figure out between JDM bling and cheap(er) but effective. In the less expensive, but still quality category, I’m looking at the Nismo S-tune springs and struts, and either the Nismo sways or the Hotchkis sways. Benefit of the Nismo parts is that they were built by Nismo and so have the engineering backup. I’ve heard that not only do they firm up the handling (with a minor .75 inch drop) but also actually get rid of some the stock porpoising the Z is known for on bumpy roads. And of course, for the buck, nothing beats those Hotchkis sways. They look fantastic, and fully adjustable (front AND rear), too.

Downside is that the Nismo S-tune isn’t adjustable for height or damping, so that’s that. Of course, I don’t want too much of a drop, and since I don’t drive it in the winter, no need to keep adjusting it.

Now, in the JDM, bling, and awesomeness category, we have the Cusco parts. Zero-2 coilovers for about 300 more than Nismo; 5 way fully adjustable damping, and height adjustable as well. For sways, I would naturally go with the Cusco bars (about 200 more than Hotchkis), where the front is adjustable, and the rear is fixed (but pretty damn stiff, from what I’ve seen). The upside is that these parts all together should work like they should, and provide a fantastic, and fully adjustable ride. The downside… the total cost is obviously more, and I don’t know if I can get the ride to where I want it. I just remember having Tein Basics on my EP, and although they did the job, the ride quality def. deteriorated a tad. Of course, since these would be ADJUSTABLE (unlike the Basics I had on the other car), I guess I could take care of that.

Anyone have anything to offer to this dilemma is greatly appreciated. I’m also willing to consider other coilover and sway packages if people want to chime in on some. I like the idea though of Cusco coilovers with Cusco sways. The coilovers are considered “soft” because they don’t stiffen the rear nearly as much as other setups, but that seems to be baked into the design because of the erection-like stiffness of their rear bar.

What you could also do is buy a set of coilovers. then buy some swift or eibach springs (they offer different sizes and spring rates) for the coilovers which are generally softer as to improve the ride. have adjustable dampers as well so you could set them to soft-medium to your liking.

Or you could balls all out and sacriface the comfort like me :D. Got my Nismo Touring 2 Race springs today. 11KG Front and 12KG back baby!

But upon reading around, nismo seems to be the best for streetability. However, spring rate is unknown… Looks like it’s softer than most coilovers out there though. My best suggestion is probably the S-tune suspension…

As for sways, cusco from reading other’s review(just like you) is pretty friggin STIFF. Not sure how much that will affect your streetability.

how about blinging it up with Tein Flex + EDFC? That way you can have the car stiff when you need, and soft when you don’t. I believe they came out with a new set of coils that’s EDFC compatible and is engineered more for the street than the track…

Thanks for the suggestions, guys. Not a fan of the Teins… I’ve heard the ride is quite stiff, and I don’t care to pay extra $$$ for the convenience of the EDFC. Plus, I’ve had Teins in the past, and I think there’s better out there.

I think I may have found another MAJOR front runner here, too. For a bit more than the Nismo S-tunes, and a little less than the Cusco Zero-2, I can land a set of the new Bilstein PSS9 height and 9 way damping adjustable coilovers. A lot of raves about how comfortable these are but still fully adjustable, and apparently Nissan offers them as OEM options in some parts of the world… THAT says something to me. Not only that, but read this article, especially their summary of the coilovers.

I’m impressed. :slight_smile:

Tein Flex is 12kg rate front and back. that’s STIFF. Not good for street at all (Yes i know my nismo is similar stfu).

The Bilsteins looks pretty good. But you have to keep in mind about one thing…
they’re usually pricey… VERY pricey…

Looks like a regular spring/shock combo with adjustable shocks. You go cheaper alternative with soft springs and adjustable shocks like koni yellows.
