Upgrading the 2023-2025 Nissan Z (RZ34) suspension is the fastest way to sharpen a chassis that Nissan built strong but tuned soft for the street. The RZ34 carries a 400-horsepower, 350 lb-ft VR30DDTT twin-turbo V6 over a double-wishbone front and multi-link rear layout – a genuinely capable platform that still rolls, dives, and sits high from the factory. Whether you want a track-ready coilover, a mild street drop, or added chassis rigidity, this guide compares the best RZ34 coilovers, lowering springs, and strut braces in stock at NLP Performance, with real spring rates, drop figures, and pricing so you can match the parts to how you actually drive.
Our Verdict
The HKS Hipermax R is the best all-around RZ34 coilover for drivers who want track-grade control without sacrificing daily livability.
With wide-range damping adjustment, 22/26 kgf/mm spring rates, and up to roughly 2.2 inches of front drop, the HKS Hipermax R gives the RZ34 a planted stance and razor turn-in. On a tighter budget, Eibach Pro-Kit springs deliver a clean 1.2-inch drop on factory dampers for $395.
Shop Our Top Pick →Why Upgrade the Nissan Z (RZ34) Suspension?
The factory RZ34 suspension is comfortable but conservative. Nissan set the 2023-2025 Z up with soft spring rates, generous ride height, and street-biased dampers that prioritize compliance over control. The chassis itself – a double-wishbone front and multi-link rear on the aluminum-intensive FM platform – is far more capable than the stock tune suggests. At 3,486 to 3,704 lb depending on transmission and trim, the Z has the mass and the 400 hp to reward a suspension that manages body roll and keeps the Brembo-equipped tires loaded through a corner.
Upgrading does three things: it lowers the center of gravity to cut body roll and dive, it firms up damping so the car settles faster over mid-corner bumps, and (with coilovers) it lets you dial in corner balance and alignment. Even a simple lowering-spring kit closes the fender gap and tightens turn-in. For drivers chasing lap times, a full coilover plus chassis bracing transforms how the RZ34 changes direction. Below we break the upgrades into three tiers – coilovers, lowering springs, and bracing – so you can spend where it matters for your build.
Best Nissan Z (RZ34) Coilovers
Coilovers are the top tier of RZ34 suspension upgrades because they combine adjustable ride height, adjustable damping, and stiffer, purpose-built spring rates in one bolt-in package. For a 400 hp rear-drive coupe, that adjustability is what lets you balance grip front-to-rear and set the exact stance and handling you want. These are the two coilover kits we recommend for the 2023-2025 Z.

Revel's 32-way adjustable Touring Sport Damper is the value coilover pick for the RZ34.
Best Nissan Z (RZ34) Lowering Springs
Lowering springs are the smartest entry point for RZ34 owners who want a better stance and tighter handling without the cost of coilovers. They reuse the factory dampers, install in an afternoon, and close the wheel gap for a noticeably lower center of gravity. Because they work with the OE shocks, choose a spring with a drop and rate that respects the stock dampers' travel – both kits below are engineered specifically for the 2023+ Z.
Eibach Pro-Kit progressive springs drop the RZ34 about 1.2 in front / 1.1 in rear on OE dampers.
Chassis Bracing: Nissan Z (RZ34) Strut Braces
Strut braces are the finishing touch on an RZ34 suspension build. By tying the tops of the strut towers together, a brace resists chassis flex under hard cornering, sharpening steering response and making the car feel more direct – especially valuable once you have stiffer springs or coilovers loading the chassis harder. Seibon's carbon-fiber braces add rigidity while trimming weight over steel bars, and they dress up the engine bay and trunk.
Seibon's carbon-fiber rear strut brace stiffens the RZ34 chassis with minimal weight.
Nissan Z (RZ34) Suspension Comparison
Here is how the six upgrades compare on type, drop, adjustability, and price so you can match the right part to your budget and driving style.
| Kit | Type | Drop (F/R) | Adjustability | Price |
|---|---|---|---|---|
| HKS Hipermax RTop Pick | Coilover | Up to -2.2 in | Height + wide-range damping | $2,880.00 |
| Revel Touring Sport Damper | Coilover | Adjustable | Height + 32-way damping | $1,145.52 |
| Seibon Rear Strut Brace | Carbon brace | – | Bolt-on rigidity | $630.00 |
| Seibon Front Strut Brace | Carbon brace | – | Bolt-on rigidity | $540.00 |
| Eibach Pro-Kit SpringsBest Value | Lowering springs | -1.2 / -1.1 in | Fixed (OE dampers) | $395.00 |
| RS-R Down Sus Springs | Lowering springs | -0.7 / -1.1 in | Fixed (OE dampers) | $309.96 |
How to Choose the Right RZ34 Suspension
Match the upgrade to how you drive. For a street car that you want to look and feel better without a big spend, start with Eibach Pro-Kit or RS-R Down Sus springs on the factory dampers – both give a clean drop for well under $400. If you want adjustability to dial in stance and ride firmness, the Revel Touring Sport Damper delivers 32-way coilover control for under $1,200. For track days and maximum control, the HKS Hipermax R's stiff rates and wide-range damping are worth the premium. Whatever springs or coilovers you choose, adding Seibon front and rear strut braces is the most cost-effective way to sharpen steering response on top. After any ride-height change, budget for a professional alignment to protect tire life and lock in the handling gains.
Frequently Asked Questions
What are the best coilovers for the 2023-2025 Nissan Z (RZ34)?
The HKS Hipermax R is the best overall coilover for the 2023-2025 Nissan Z (RZ34), with track-grade 22/26 kgf/mm spring rates, wide-range damping adjustment, and up to roughly 2.2 inches of front drop. For a street-focused, value-driven option, the Revel Touring Sport Damper offers 32-way adjustable damping and full ride-height control for under $1,200. Both are direct bolt-on kits for the RZ34.
How much does it cost to upgrade the suspension on a Nissan Z (RZ34)?
RZ34 suspension upgrades range from about $305 to $2,880 at NLP Performance. Lowering springs like the RS-R Down Sus ($304.79) and Eibach Pro-Kit ($395) are the most affordable path, adjustable coilovers such as the Revel Touring Sport Damper run around $1,126, and the flagship HKS Hipermax R coilover kit is $2,880. Carbon strut braces add $540-$630 each.
Do lowering springs work with the factory Nissan Z dampers?
Yes. Both the Eibach Pro-Kit and RS-R Down Sus lowering springs are designed to work with the factory RZ34 dampers. They are engineered with progressive or matched rates and modest drop figures so the OE shocks retain enough travel. If you plan to lower more than about 1.2 inches or want adjustable damping, step up to a coilover kit instead.
How low can you drop a 2023+ Nissan Z (RZ34)?
On lowering springs, expect about 1.1 to 1.2 inches with the Eibach Pro-Kit or a milder 0.6 to 1.2 inches with the RS-R Down Sus. Coilovers go lower and are fully adjustable – the HKS Hipermax R offers up to roughly 2.2 inches of front drop. Going lower than spring kits allow requires coilovers so the dampers keep adequate travel.
Coilovers vs lowering springs for the Nissan Z: which is better?
Coilovers are better if you want adjustable ride height, adjustable damping, and stiffer purpose-built spring rates for spirited or track driving. Lowering springs are better if you want a clean drop and improved handling at a low cost while keeping the factory dampers and ride comfort. For most RZ34 street builds, springs are the value choice; for track use, coilovers win.
Do strut braces make a difference on the Nissan Z (RZ34)?
Yes. A strut brace ties the strut towers together to resist chassis flex under hard cornering, which sharpens steering response and makes the RZ34 feel more direct. The benefit is most noticeable once you have stiffer springs or coilovers. Seibon's carbon-fiber front and rear braces add rigidity while weighing less than steel bars.
Will Nissan Z RZ34 suspension parts fit a 370Z?
No. The 2023+ Nissan Z (RZ34) rides on a revised chassis, and RZ34-specific springs, coilovers, and strut braces are not interchangeable with the 370Z (Z34). Always order suspension parts by the exact chassis code – the products in this guide are RZ34-specific fitments for the 2023-2025 Nissan Z.
