The Infiniti G37 has a willing chassis, but the factory shocks and tall springs leave plenty of body roll and a fender gap that begs to be closed. A good set of coilovers transforms how this car turns in, holds a line, and looks parked in your driveway. The catch is that the G37 platform shares a lot with the 370Z, so fitment is wide, quality varies, and the wrong set will either ride like a brick or sag within a season.
We focused on coilovers that genuinely fit the G37 coupe and sedan, balancing daily comfort against grip. For each pick below we look at damping adjustment, spring rates, build materials, and how it actually behaves over broken pavement, not just on a smooth dyno floor. Whether you want a comfortable lowered cruiser or a corner-carving track setup, one of these seven will match your goals.

1. BC Racing BR Series Coilovers: Best Overall
The BC Racing BR Series is the coilover most G37 owners land on, and for good reason. It nails the middle ground that this car needs, offering enough firmness to flatten the body roll the G37 is known for while staying livable on a daily commute. The 30-way damping knob is genuinely usable across its range, so you can soften it for a road trip and stiffen it for a canyon run without touching the ride height. Independent spring and damper adjustment means you do not sacrifice suspension travel to get the stance you want, which is a common failing in entry-level kits.
The honest weakness is the firm end of the damping range. Crank it past the mid-twenties and sharp impacts like tar strips and pothole edges get harsh, so most street drivers settle somewhere in the lower half. Rear ride height on the coupe also means pulling the strut to twist the perch, which is a known G37 annoyance rather than a BC flaw. None of that undercuts the value here, because few kits give you this much tunability and proven durability in one box.
- 30 levels of damping adjustment for street and track tuning
- Independent height and damping so you keep travel when lowered
- Front camber plates included on most G37 kits
Pros: Huge adjustment range covers daily comfort to aggressive track use; Strong reputation for longevity and easy rebuilds; Spring rates chosen well for the G37 weight balance
Cons: Top setting can feel firm over expansion joints; Rear height adjustment requires removing the strut on coupe
2. Tein Street Advance Z Coilovers: Best for Daily Comfort
If your G37 is primarily a daily driver that you want lower and tighter without punishing your spine, the Tein Street Advance Z is the smart choice. Tein tuned this kit for comfort first, using a twin-tube damper and moderate spring rates that take the edge off the kind of rough city streets that turn cheaper coilovers into a chiropractor referral. The 16 clicks of adjustment let you dial in a soft, compliant ride or firm things up for a spirited weekend, and EDFC compatibility means you can add a controller to change damping from the driver seat.
The trade-off for that plushness is body control when you really push. On a track day the softer valving lets the nose dive under hard braking and the chassis takes a beat to settle compared to a stiffer setup. That is the deliberate cost of comfort, not a defect, and for the street-driven G37 it is exactly the right priority. Build quality is classic Tein, meaning the damping stays consistent season after season rather than fading like budget units do.
- 16-click damping force adjustment tuned for street comfort
- Twin-tube construction soaks up rough roads better than most
- EDFC electronic controller ready for in-cabin damping changes
Pros: Smoothest riding coilover here for everyday driving; Reliable Tein quality with consistent damping over time; Lower spring rates keep the cabin calm on broken pavement
Cons: Less body control at the limit than a track-focused kit; Fewer damping clicks than the BC Racing range
3. Megan Racing EZ II Street Coilovers: Best Value
The Megan Racing EZ II Street is the pick for the owner who wants real coilover adjustability without stretching the budget. You get 32 clicks of damping from a single knob, pillowball top mounts that sharpen turn-in, and a monotube front that responds more crisply than the twin-tube units in this class. On the G37 it firms up the floaty factory feel nicely and lets you sit the car at an aggressive but still drivable height. For a first set of coilovers, it punches well above its station.
Where it gives ground is long-haul durability. The Megan dampers are good out of the box, but owners report damping consistency and seal life that do not quite match Tein or BC over many years and hard miles. Treat it as a strong value setup rather than a forever kit and you will be happy. Also budget for a fender roll if you plan to slam it, since the wider drop can catch the lip on stickier tires.
- 32-way single-knob damping adjustment for fine tuning
- Monotube front dampers for sharper response
- Pillowball top mounts reduce deflection and slop
Pros: Strong feature set for the money with wide adjustment; Sharper steering feel than the spring rates suggest; Popular fitment with lots of G37 owner feedback
Cons: Long-term durability trails the premium Japanese brands; Some kits need fender rolling at full drop
4. KW Variant 3 Coilovers: Best Premium
The KW Variant 3 is the engineering-led choice for a G37 owner who wants a genuinely refined result and is willing to spend time tuning it. Unlike single-knob coilovers, the V3 lets you set compression and rebound damping independently, so you can control how the car absorbs bumps separately from how it settles after them. The stainless steel strut bodies will not rust out from road salt the way painted units eventually do, and the whole kit feels like a factory upgrade rather than an aftermarket compromise. On the G37 it delivers a planted, composed ride that flatters fast road driving.
The honest caveats are twofold. First, this is a premium kit and it asks for a premium commitment, so it is overkill for someone who just wants to drop the car an inch. Second, the dual adjustment that makes it so capable also makes it more work to get right, since you have two variables to balance instead of one. If you enjoy dialing in suspension and want a set that lasts the life of the car, the V3 rewards that patience better than anything else on this list.
- Separately adjustable compression and rebound damping
- Inox stainless steel struts resist corrosion for life
- TUV approved with a refined factory-style ride feel
Pros: Separate bump and rebound control for precise tuning; Stainless construction outlasts painted steel bodies; Refined, planted ride that feels engineered not harsh
Cons: Premium build sits at the top of the value spectrum; Adjustment is more involved than a single-knob kit
5. Godspeed MonoSS Coilovers: Best Budget Pick
For the G37 owner on a tight budget who still wants real coilovers instead of a cheap lowering spring, the Godspeed MonoSS is the entry point. It is a genuine mono-tube design at all four corners with 16 levels of damping and front camber plates in the box, which is a lot of hardware for an affordable kit. On the car it closes the fender gap convincingly and gives you a noticeably tighter, more connected feel than the soggy factory setup, which is exactly what most first-time buyers are after.
The compromises are predictable for the price. The damping range is narrower and less linear than the BC or KW kits, so the gap between comfortable and firm is smaller and the firm end can feel busy over choppy roads. Long-term seal life is the usual budget question mark, so inspect for weeping after a year. Within its lane, though, the MonoSS is an honest set that lets you get your G37 sitting right and handling better without overspending.
- Mono-tube dampers across all four corners
- 16 levels of damping for street tuning
- Front camber plates included for alignment correction
Pros: Most affordable full coilover set that still adjusts; Camber plates included help dial in lowered geometry; Wide height range gets a serious drop
Cons: Damping range is narrower than premium kits; Ride can get busy on rough surfaces at firmer settings
6. Fortune Auto 500 Series Coilovers: Best for Track
When the G37 is headed to the track, the Fortune Auto 500 Series is the kit built for the job. These are made to order, so you can specify spring rates and valving matched to your weight, tire, and event mix instead of accepting a generic curve. The large-piston mono-tube design manages the heat that builds during sustained sessions far better than budget dampers that fade after a few laps, and the whole unit is rebuildable, so a hard track life does not turn it into landfill. On a corner-focused G37 it delivers the body control and consistency that lap times depend on.
The flip side is exactly what makes it great on track. The firmer valving and higher rates that keep the car flat through a corner make it stiff and busy on a rough commute, so this is not the kit for a comfort-first daily. The custom build also means a wait while it is assembled to your spec, rather than grabbing a box off the shelf. If your priority is the track and you want something that lasts and can be tuned forever, that wait pays off.
- 24-way damping with custom spring rate options
- Mono-tube design with large piston for track heat
- Fully rebuildable and revalvable for the long term
Pros: Built to order with valving matched to your use; Handles sustained track heat better than most; Rebuildable so it lasts through years of hard use
Cons: Aggressive valving makes it firm for pure street use; Lead time on custom builds is longer than off-the-shelf
7. Yellow Speed Racing Dynamic Pro Sport Coilovers: Most Adjustable
The Yellow Speed Racing Dynamic Pro Sport is for the G37 owner who loves to tinker. With 33 levels of damping it offers the finest adjustment granularity on this list, letting you creep up on exactly the ride you want one click at a time. Independent height adjustment keeps your shock travel intact when you drop the car, front camber plates help you correct the lowered geometry, and the mono-tube dampers respond cleanly. As a do-it-all street setup that can handle the occasional track day, it covers a lot of ground for sensible money.
That deep adjustment is also the catch. Thirty-three clicks sound great until you are chasing your sweet spot and every change feels marginal, so dialing it in takes patience and a notebook. The brand also has a smaller footprint than BC, Tein, or KW, which means fewer local installers familiar with it and a thinner support network if you need parts. For a hands-on owner who enjoys the tuning process, though, this kit delivers a lot of capability and flexibility.
- 33 levels of damping for very fine control
- Independent height adjustment preserves shock travel
- Front camber plates included for lowered alignment
Pros: Widest click range here for granular tuning; Good value for the feature count and adjustment; Solid street and weekend track all-rounder
Cons: So many clicks make finding your sweet spot tedious; Brand support is thinner than the big names
Frequently Asked Questions
Will G37 coilovers also fit a 370Z or G35?
Often yes, because the Infiniti G37, G35 sedan, and Nissan 370Z share the same FM platform and very similar suspension geometry. Most major coilover brands list a single part number that covers the G37 coupe, G37 sedan, and 370Z, though you should always confirm the exact body style and whether your car is rear-wheel or all-wheel drive before buying. The G35 uses an earlier version of the platform, so a few kits are model-specific. Check the brand’s fitment listing for your exact year and trim rather than assuming, since a 370Z-only kit can have slightly different rear hardware than a G37 sedan needs.
Do I need an alignment after installing coilovers on my G37?
Yes, an alignment is essential after any coilover install on the G37. Lowering the car changes camber and toe significantly, and the G37 in particular gains a lot of negative camber when dropped, which will chew through the inner edges of your tires fast if left uncorrected. Get a professional alignment as soon as the car is at its final ride height, and if you have lowered it aggressively you may also want camber and toe arms to bring the numbers back into a safe range. Several kits on this list include front camber plates, which give you some adjustment up front, but the rear of the G37 usually needs adjustable arms to fully dial in.
How low can I drop a G37 on coilovers without problems?
Most G37 owners settle on a drop of roughly one to two inches for a clean look that still drives well and keeps enough suspension travel. You can go lower, but past about two inches you start running into rubbing on the fender liners and lip, reduced shock travel that makes the ride crashy, and steeper camber that needs correction arms. The coupe and sedan also have slightly different clearances. If you want to slam it for stance, plan on rolling and possibly pulling the fenders, fitting camber and toe arms, and accepting a firmer ride. For a balance of looks and daily usability, a moderate drop on a kit with independent height and damping like the BC Racing BR is the sweet spot.
Are coilovers worth it over lowering springs on a G37?
For most enthusiasts, yes. Lowering springs on the factory shocks will drop the car and look better, but the standard dampers are not valved for the stiffer spring and will wear out faster while giving a bouncy, underdamped ride. Coilovers replace the spring and damper as a matched unit, so the damping is correct for the spring rate, and you get adjustable ride height plus adjustable damping to tune comfort versus control. That flexibility is the real reason coilovers are worth it on the G37. If you only ever want a mild drop and never plan to tune anything, springs are cheaper, but coilovers are the better long-term answer for a car you want to handle and sit right.
Can I install G37 coilovers myself in my garage?
It is doable for a confident home mechanic with the right tools, but it is not a beginner job. You will need a solid jack and stands, a spring compressor only if you are reusing parts, penetrating oil for the inevitably seized bolts, and patience for the rear of the G37, where the strut often has to come out to set ride height. Budget a full day for your first time, work safely with the car properly supported, and torque everything to spec. The single biggest thing to remember is that you must get a professional alignment afterward, because no garage install is complete until the camber and toe are corrected for the new ride height.
Our Verdict
For most G37 owners, the BC Racing BR Series is the coilover to buy. It blends a usable 30-way damping range, independent height and damping adjustment, and proven durability into a kit that handles both a daily commute and a weekend canyon run without complaint. If your G37 lives on rough city streets and comfort is your top priority, the Tein Street Advance Z is the runner up, riding smoother than anything else here while still tightening up the floaty factory feel. Match the kit to how you actually drive and either one will transform the car.
