Buckle up, because I’m about to tell you why the TEIN Street Advance Z coilovers are a game-changer for your ride. As someone who’s spent countless hours tweaking my car’s suspension for that perfect balance of comfort and performance, I can confidently say these coilovers are worth every penny.
They’re affordable, adjustable, and deliver a ride quality that makes daily commutes and spirited drives equally thrilling. Whether you’re cruising city streets or carving up backroads, the Street Advance Z will transform your driving experience.
Trust me, you’ll want these on your car.
My Journey With TEIN Street Advance Z
Let me take you back to when I first decided to upgrade my suspension.
I drive a 2015 Honda Civic Si, and while it’s a fun car stock, the factory suspension left me wanting more—especially on Charlotte’s pothole-ridden roads.
My steering wheel would shimmy at 70 mph, and taking on-ramps above 40 felt like I was risking a rollover.
I’d been eyeing coilovers for a while, and after reading reviews and forum posts, I pulled the trigger on the TEIN Street Advance Z coilovers.
At around $650, they were a steal compared to pricier options, and the 16-level damping adjustability sealed the deal.
Installation wasn’t a nightmare, but it wasn’t a walk in the park either. I enlisted a buddy who’s handy with a wrench, and we got them on in a weekend.
The instructions were clear, but setting the preload took some trial and error—I’ll get to that later.
Once installed, the difference was night and day. My Civic felt glued to the road. The steering tightened up, and that annoying vibration at highway speeds?
Gone.
I took it for a spin on a twisty B-road, and the car handled like it was on rails, even at 50 mph. On softer settings, it’s comfortable enough for my daily commute, but crank the damping up, and it’s ready for spirited driving.
What surprised me most was how versatile these coilovers are. I’m no track rat, but I love a good canyon carve, and the Street Advance Z lets me dial in the ride exactly how I want it.
I’ve had them for over a year now, and they’ve held up beautifully through potholes, speed bumps, and the occasional “spirited” drive. If you’re looking for an affordable way to level up your car’s handling without sacrificing comfort, these are a no-brainer.
Pros of TEIN Street Advance Z Coilovers
- Affordable Price Point
Let’s talk money—you’re getting a lot of bang for your buck with the Street Advance Z.
At around $600-$700, they’re significantly cheaper than high-end options like KW V3 or HKS Hipermax, which can run you $1,500 or more.
For a daily driver like me, who wants performance without breaking the bank, this price is a sweet spot.
You’re not skimping on quality either; TEIN’s reputation for durability and performance shines through, even at this budget-friendly level.
- 16-Level Damping Adjustability
The star of the show is the 16-level damping adjustment. This feature lets you fine-tune the ride from plush to firm, depending on your mood or driving conditions.
I keep mine at about 10 clicks from the softest setting for daily driving—smooth enough to handle rough roads but firm enough for confidence in corners.
If I’m hitting a twisty road, I’ll dial it up to 5 clicks from max for that extra stiffness. It’s like having two suspensions in one, and adjusting is as simple as turning a knob with the included tool.
- Twin-Tube Design for Comfort
The twin-tube design is a big win for street use. Unlike monotube coilovers, which can feel harsh on bumpy roads, the Street Advance Z’s twin-tube setup offers more shock travel, making it ideal for daily drivers.
I’ve driven over some gnarly potholes, and while I still brace myself, the ride isn’t jarring. It absorbs bumps better than my stock setup ever did, and it’s a noticeable improvement over cheaper monotube options.
- Height Adjustability for That Perfect Stance
Want to slam your car or keep it practical? The Street Advance Z lets you adjust ride height to your liking. I dropped my Civic about 1.5 inches for a clean, tucked look without scraping everywhere.
The adjustment is done via the spring perch, which is straightforward once you get the hang of it. Just make sure you measure carefully to keep all four corners even—trust me, I learned this the hard way.
- Compatibility with EDFC System
Here’s a cool bonus: the Street Advance Z is compatible with TEIN’s Electronic Damping Force Controller (EDFC). This system lets you adjust damping from inside the car, which is perfect if you’re constantly switching between comfort and performance modes.
I haven’t splurged on it yet (it’s an extra $400 or so), but knowing it’s an option for future-proofing is awesome. It’s like TEIN’s saying, “We’ve got your back if you want to take it to the next level.”
- Durable Build Quality
TEIN’s known for building stuff that lasts, and the Street Advance Z is no exception. After a year of daily driving, including some brutal winter conditions, mine still feel as solid as day one. The shocks are sealed units, so they’re not rebuildable, but at this price point, replacing them every few years isn’t a dealbreaker.
Plus, TEIN’s testing process—tailored to specific regions’ road conditions—means these are built to handle whatever your local streets throw at them.
Not-So-Good Parts of TEIN Street Advance Z Coilovers
- Non-Rebuildable Shocks: One downside is that the Street Advance Z shocks are sealed, meaning you can’t rebuild them if they wear out. TEIN estimates they last about 36,000 miles, which is decent for the price, but if you’re used to rebuildable high-end coilovers, this might sting. When mine eventually wear out, I’ll need to buy new shocks, which could cost as much as a rebuild on pricier setups. For me, the trade-off is worth it given the initial cost savings, but it’s something to keep in mind.
- Installation Can Be Tricky: Installing these isn’t rocket science, but it’s not plug-and-play either. Setting the preload correctly requires patience and precision. I accidentally set mine unevenly at first, which made the front left corner sit lower. Fixing it meant re-measuring and adjusting, which was a hassle. If you’re not mechanically inclined, you might want to budget for a professional install—expect to pay $200-$400 depending on your shop. Also, you’ll need an alignment afterward, so factor that in.
- Floaty Feel on Softest Settings: While the damping adjustability is awesome, the softest settings can feel a bit floaty, especially during aggressive driving. I noticed this when I took a corner a bit too enthusiastically on the softest setting—it felt like the car was bobbing more than I’d like. It’s not a dealbreaker, but if you’re planning to push your car hard, you’ll want to keep the damping firmer. For daily driving, though, the softer settings are plenty comfortable.
- OEM Top Mounts Required: Unlike the pricier TEIN Flex Z, which often includes upper mounts, the Street Advance Z relies on your car’s OEM top mounts. If yours are worn out (like mine were), you’ll need to replace them, adding to the cost. I spent about $100 on new Accord mounts for my Civic, and modifying them to fit took some extra effort. It’s not a huge issue, but it’s an extra step you might not expect.

Maintenance Tips For TEIN Street Advance Z Coilovers
- Regularly Check Preload and Ride Height
To keep your Street Advance Z performing like new, check the preload and ride height every few months, especially if you’re driving on rough roads. I made the mistake of ignoring mine for a while, and one corner started sitting lower after hitting a particularly nasty pothole.
Use a tape measure to ensure the thread distance from the bottom collar to the locking tab matches TEIN’s recommended settings (typically 198-200mm front, 249-250mm rear, but check your manual). Adjust as needed and tighten everything down to prevent slipping.
- Clean and Lubricate Threads
Road grime and salt can build up on the coilover threads, making height adjustments a pain. Every six months, I clean the threads with a wire brush and some degreaser, then apply a thin layer of anti-seize lubricant.
This keeps the collars moving smoothly and prevents corrosion, especially in salty winter climates. It takes maybe 30 minutes, but it’s worth it to avoid seized components down the line.
- Inspect for Leaks and Wear
Since these shocks are sealed, you’ll want to keep an eye out for any signs of leakage or wear. I check mine during oil changes—just look for oil residue around the shock body or any unusual noises like clunking. If you spot a leak, it’s time to replace the shock.
TEIN’s customer service is pretty responsive, so reach out to them for replacement parts if needed. Catching issues early can save you from bigger headaches.
- Get Regular Alignments
Lowering your car messes with your alignment, so get it checked every 6,000 miles or after any height adjustments. I learned this the hard way when my tires started wearing unevenly after dropping my Civic.
A good alignment shop will set your camber and toe to spec, which not only preserves your tires but also keeps the handling crisp. I spring for a lifetime alignment deal at my local shop—it’s paid for itself after a few height tweaks.
- Adjust Damping for Conditions
Don’t just set the damping and forget it. I adjust mine based on the season—softer in winter for extra comfort on icy roads, firmer in summer for better handling during spirited drives. It only takes a few minutes with the adjustment tool, and it keeps the ride tailored to your needs.
If you notice the ride getting harsh or floaty, experiment with a few clicks in either direction to find your sweet spot.
Comparison With Other Brands: TEIN Street Advance Z Vs. The Competition
Let’s see how the TEIN Street Advance Z stacks up against some heavy hitters in the coilover world: Five8, Godspeed Mono SS, and Bilstein B16.
I’ve driven on or researched these alternatives, so I’ll break it down with a focus on what you’re getting for your money, how they feel on the road, and what makes each one stand out—or fall short. My goal is to help you figure out which coilover fits your driving style, whether you’re cruising daily or chasing corners.
- TEIN Street Advance Z Vs. Five8 Coilovers
Five8 coilovers, priced around $800-$900, are a solid option for budget-conscious tuners who want a bit more flair than entry-level kits. They’re popular in the stance scene, offering height adjustability and a decent 16-level damping range, much like the TEIN Street Advance Z.
I test-drove a friend’s Subaru WRX with Five8s, and the ride was noticeably stiffer than my TEINs, even on softer settings. This is because Five8 uses a monotube design, which prioritizes performance over comfort. If you’re hitting the track often, that stiffness might be a plus, but for daily driving on rough roads like mine in Charlotte, the TEIN’s twin-tube setup soaks up bumps better.
Five8s also come with camber plates on some models, which is great for aggressive alignments, but you’re paying extra for that feature. The TEINs, at $600-$700, give you similar adjustability and better street comfort for less cash.
However, Five8’s build quality feels a touch less refined—my friend had to replace a leaky shock after 18 months, whereas my TEINs are still rock-solid after a year.
- TEIN Street Advance Z Vs. Godspeed Mono SS Coilovers
Godspeed Mono SS coilovers are the budget king, often retailing for $500-$600, making them slightly cheaper than the TEIN Street Advance Z.
I’ve got a buddy who runs these on his Mazda Miata, and he swears by them for the price.
They offer 16-level damping and height adjustability, but the monotube design makes them harsher over potholes compared to TEIN’s twin-tube setup.
I drove his car, and while it handled great on smooth roads, hitting a rough patch felt like a punch to the spine.
Godspeed’s spring rates are also stiffer out of the box, which is awesome for autocross but less forgiving for daily commutes.
Another downside?
Godspeed’s reputation for longevity isn’t as strong—online forums mention leaks or fading performance after 20,000 miles.
My TEINs, on the other hand, have held up through a year of mixed driving without a hiccup. If you’re on a super tight budget and prioritize performance over comfort, Godspeed’s a tempting choice, but the TEINs edge out for their smoother ride and proven durability.
- TEIN Street Advance Z Vs. Bilstein B16 Coilovers
Now, let’s talk premium: the Bilstein B16 coilovers, which run $1,800-$2,200.
These are the gold standard for enthusiasts who want track-ready performance with street usability.
I had the chance to ride in a BMW 3-Series with B16s, and the difference is undeniable—they’re precise, composed, and handle like a dream, even at high speeds.
Bilstein’s monotube inverted design and 10-level damping adjustment offer a sharper response than the TEIN’s 16-level setup, but the trade-off is a firmer ride.
On city streets, the B16s felt stiffer than my Street Advance Z, especially over speed bumps.
The Bilsteins also include adjustable camber plates and are rebuildable, which justifies the price if you’re a track junkie planning to keep them for years. However, for my daily-driven Civic, the TEINs deliver 80% of the B16’s performance at a third of the cost.
If you’re not chasing lap times, the Street Advance Z’s affordability and street-focused comfort make it a better pick for most drivers. Plus, TEIN’s compatibility with the EDFC system gives it a future-proof edge that Bilstein lacks.
Why TEIN Street Advance Z Stands Out?
Across these comparisons, the TEIN Street Advance Z hits a sweet spot for enthusiasts like me who want versatility without the premium price tag. Its twin-tube design prioritizes daily comfort over the stiffer monotube setups of Five8 and Godspeed, making it ideal for mixed driving.
While Bilstein B16s are a step above in precision, they’re overkill for most street applications, and their cost is hard to justify unless you’re a serious track rat. The TEINs give you 16-level damping, height adjustability, and solid build quality for $600-$700, making them a no-brainer for budget-conscious drivers who still want to carve corners.
You’re getting near-premium performance with a wallet-friendly price, and that’s tough to beat.

Frequently Asked Questions (FAQ)
TEIN estimates their coilovers, including the Street Advance Z, last about 36,000 miles before needing an overhaul or replacement. In my experience, with proper maintenance—like regular cleaning and alignment checks—you can stretch this closer to 50,000 miles, especially if you’re not slamming your car or driving on terrible roads daily. It depends on your driving habits and conditions, but I’ve had mine for over a year with no issues so far.
The TEIN Street Basis Z is height-adjustable via the spring perch, just like the Street Advance Z, but it lacks damping adjustability. You’re stuck with a fixed damping setting, which TEIN sets to a middle-ground feel. If you don’t plan on tweaking the firmness, the Basis Z is a great budget option, but I prefer the Street Advance Z for its 16-level damping flexibility.
Not entirely. The Street Advance Z and Basis Z are manufactured in China to keep costs down, but TEIN’s higher-end Flex Z coilovers are still made in Yokohama, Japan. That said, TEIN’s quality control is top-notch across the board, and my Street Advance Z feels just as solid as any JDM part I’ve owned. They design their suspensions with region-specific road conditions in mind, which adds to their durability.
The TEIN Flex Z allows for significant lowering, typically 2-3 inches below stock height, depending on the car. Exact specs vary by vehicle, so check TEIN’s application chart for your model. Unlike the Street Advance Z, the Flex Z adjusts height via the shock body, not the spring perch, giving you more range. Just be warned—going too low can mess with your alignment and suspension geometry, so don’t slam it without proper setup.
Conclusion: Why You Should Get TEIN Street Advance Z Coilovers
After a year of living with the TEIN Street Advance Z, I’m sold. They’ve transformed my Civic into a car that’s both a comfy daily driver and a corner-carving beast when I want it to be. For the price, the adjustability, durability, and ride quality are unmatched.
If you’re ready to elevate your driving experience without emptying your wallet, these coilovers are the way to go. Buy them, install them, and enjoy the ride—you won’t look back.
