1. KW Variant 3 Coilover Kit: Best Overall
The KW Variant 3 delivers exceptional performance with its independent rebound and compression adjustment, allowing fine-tuning for both daily driving and track days. Based on owner feedback, the stainless steel construction holds up well in harsh climates, and the TUV certification adds confidence. However, the cost is significantly higher than many competitors, making it a serious investment for enthusiasts who prioritize control and durability.
This kit is best for drivers who want a dual-duty setup and are willing to pay for quality. If you are on a tight budget or only need basic adjustability, skip this and consider the BC Racing or Tein options instead.
- Independent adjustment of rebound and compression damping for precise tuning
- Stainless steel bodies resist corrosion, tested to TUV standards
- Height adjustable without affecting spring preload
Pros: Excellent ride quality on street and track; High build quality and corrosion resistance
Cons: Premium pricing may not suit budget builds; Requires professional installation for optimal setup
2. Ohlins Road & Track DFV Coilovers: Top Premium Pick
The Ohlins Road & Track DFV coilovers are revered for their Dual Flow Valve technology, which maintains consistent damping regardless of road conditions. In our evaluation using published technical data and owner reviews, this kit offers remarkable traction and comfort. The aluminum construction reduces weight, but the cost is prohibitive for most, and replacement parts are costly.
This is the choice for the dedicated track enthusiast who demands the best. If you do not need extreme performance or cannot justify the expense, the KW V3 or BC Racing BR series offer strong alternatives at lower cost.
- DFV technology ensures consistent damping in both directions
- Lightweight aluminum body reduces unsprung mass
- Separate height and spring preload adjustment
Pros: Superb ride compliance and grip; Race-proven technology at a high level
Cons: Very expensive, not for budget-conscious buyers; Limited availability and long wait times
3. BC Racing BR Series Coilovers: Best Value
The BC Racing BR series is a popular choice among 370Z owners for its balance of features and price. With 30 levels of damping adjustment and pillow ball mounts, it offers significant tuning capability. Based on aggregated owner feedback, the ride is firm but controlled, though some have noted corrosion in salt-belt climates. The rebuild service adds long-term value.
This is ideal for daily drivers who want to lower the car and improve handling without breaking the bank. If you need a plush ride or live in a snowy area, consider the KW V3 or Tein Flex Z for better corrosion resistance.
- 30-level adjustable damping for versatile setups
- Pillow ball upper mounts allow camber adjustment
- Monotube design for consistent damping
Pros: Excellent value for adjustability; Great customer support and rebuild service
Cons: Ride can be firm on rough roads; Some owners report corrosion after winter use
4. Tein Flex Z Coilovers: Best for Daily Driving
The Tein Flex Z is designed for street comfort, featuring a full-length height adjustment that maintains shock travel. Owner feedback highlights a compliant ride that soaks up bumps well, making it suitable for daily driving. However, the damping adjustability is narrower than some rivals, and the valving is not optimized for aggressive track use.
This is perfect for those who want a mild drop and improved handling without sacrificing comfort. If you plan to track your 370z frequently, consider the BC Racing BR or KW V3 for more aggressive tuning.
- Full-length height adjustment without affecting ride travel
- Compatible with Tein EDFC for electronic damping control
- Durable construction with anti-corrosion coating
Pros: Comfortable ride for daily use; Easy height adjustment
Cons: Limited damping adjustment range; Not as track-focused as competitors
5. Megan Racing EZ Street Series Coilovers: Budget Pick
The Megan Racing EZ Street coilovers are a budget-friendly option that provides basic height and damping adjustability. They come pre-assembled with camber plates, simplifying installation. However, based on owner feedback, the ride quality is stiff and can be jarring on uneven roads, and some have reported premature wear or leaking.
This kit suits those on a strict budget who need a lowered stance and occasional spirited driving. If you prioritize ride comfort or long-term durability, spend more on the BC Racing or Tein Flex Z.
- 32-level damping adjustment
- Pre-assembled with camber plates
- Affordable entry into coilovers
Pros: Low price point; Includes camber plates
Cons: Harsh ride on rough pavement; Lower build quality than premium brands
6. ST Suspensions XTA Plus Coilovers: Entry Level Performance
The ST Suspensions XTA Plus offers a galvanized steel body that resists rust better than some budget options. It provides 20 clicks of damping adjustment and separate height and preload settings. However, owner reviews indicate the damping range is narrow, and the ride can be bouncy on undulating roads. It is a step up from lowering springs but falls short of more refined kits.
This is a good choice for a daily driver that sees occasional spirited driving and where budget is a primary concern. If you plan to autocross or track the car, look at the BC Racing BR or KW V3.
- Galvanized steel construction for corrosion resistance
- 20-click damping adjustment
- Separate height and spring preload adjustment
Pros: Good corrosion resistance for the price; Decent entry-level adjustability
Cons: Limited damping range; Not suitable for heavy track use
7. Cusco Street Zero A Coilovers: Unique Adjustability
The Cusco Street Zero A features an Active Oil System that minimizes aeration for more consistent damping. It offers 30 levels of adjustment and comes with front pillow ball mounts. Based on technical specs and owner feedback, the ride is firm even on the softest setting, making it less comfortable for daily driving. Parts availability is also a concern outside Japan.
This kit appeals to enthusiasts who want a unique technology and don’t mind a firm ride. If you prioritize comfort or need easy parts access, the Tein Flex Z or BC Racing BR are better options.
- AOS technology reduces oil foaming for consistent damping
- 30-level damping and independent height adjustment
- Includes front pillow ball mounts
Pros: Unique AOS improves consistency; Good build quality from Japanese brand
Cons: Stiffer than competitors on softest setting; Replacement parts can be hard to source
Frequently Asked Questions
What spring rates should I choose for my 370Z coilovers?
Spring rates depend on your use. For a daily driver, rates around 6-8 kg/mm front and 7-9 kg/mm rear are common. For track use, 10-14 kg/mm front and 10-12 kg/mm rear are typical. Many coilover kits come with preset rates; check manufacturer recommendations.
Can I install coilovers myself?
Installation requires mechanical experience, proper tools, and a torque wrench. You will also need an alignment after installation. If you are not confident, professional installation is recommended to ensure safety and performance.
How long do coilovers last?
Lifespan varies by brand and usage. Premium coilovers like KW or Ohlins can last 50,000-100,000 miles with proper maintenance. Budget options may need replacement sooner. Regular cleaning and avoiding harsh environments extend life.
Will coilovers affect ride comfort significantly?
Yes, most coilovers are stiffer than stock. However, some kits like the Tein Flex Z are designed for comfort. Adjustable damping allows you to soften the ride, but expect a firmer feel overall.
Do I need camber arms with coilovers?
Many coilovers include pillow ball mounts that provide some camber adjustment. However, for significant lowering, aftermarket camber arms are recommended to maintain proper alignment and prevent uneven tire wear.
Our Verdict
After our research and comparison, the KW Variant 3 earns the top pick for its blend of performance, durability, and adjustability, making it suitable for both street and track use. The Ohlins Road & Track DFV is the runner-up for those seeking the ultimate in race-derived technology, though at a higher cost. For most drivers, the BC Racing BR series offers the best value.
