Are you looking to lower your Infiniti Q50 or improve its handling performance? Whether you are building your Q50 for the street or the track, one of the best ways to do this is to install a set of Q50 coilovers.
In this blog post, I’m going to cover the benefits of buying coilovers for the Q50 along with the 12 best coilover options available on the market today.
The Best Coilovers for the Infiniti Q50
BC Racing BR Series
Lowering: 1-3 inches, 2-4 inches on the Extreme Low option

The BC Racing BR Series is one of the most popular coilover kits in the whole world, and for several good reasons.
As BC Racing’s entry level kit, it does a superb job of being the perfect all-rounder that can handle both comfortable daily riving and track duty, all for an impressively low price.

If you are looking for a high performance coilover you can spec to your requirements, this is it.
The Fortune Auto 500 Series is a very impressive coilover kit offering several things few other kits do.
For starters, these coilovers are modular, meaning they can be upgraded. So if you find that you need to upgrade your kit, say with 2-way adjustable dampening and external reservoirs, you don’t need to buy a whole new kit. Instead, you send yours in to Fortune Auto and they will upgrade them for you.
These coilovers are hand assembled at Fortune Auto’s Virginia facility, and every single damper is put on a shock dyno, tested and matched in pairs to within a 3% tolerance. This ensures that every single kit that leaves their facility is made to the highest standard.
And to back that up, they offer a 5 year warranty, which is one of the longest of any brand and says a lot about how much they believe in their product.
The dampers are monotube, giving you 24 levels of rebound adjustment and use high pressure nitrogen and a high flow digressive piston which gives the driver more feel and control over the car. They have also incorporated a “blow-off” technology to keep the ride comfortable even over rough surfaces.
The springs are made from premium chrome silicon alloy which ensures superior performance, ride quality and a long life with minimal sagging. Swift Springs are available as an optional extra if you want to upgrade to the absolute best.
Fortune Auto will also customize these coilovers to suit your needs including custom spring rates and valving, and they even have a super low option if you really want to slam your car.
These coilovers are a fantastic choice for both street cars and cars that will see the track, and aren’t even that expensive compared to other high-end coilovers.

The Silvers Neomax coilovers are actually very similar to the Fortune Auto’s but a bit cheaper.
Silvers have very similarly strict quality controls like Fortune Auto and also hand assemble every kit, along with testing every damper on the shock dyno and only using them if they are within a 5% tolerance, otherwise they get scrapped.
Silvers also pride themselves on extremely fast turn-around times, getting kits completed within 10 days including custom orders.
Also similar to the Fortune Auto 500’s, the Neomax are modular, giving you the option to upgrade to 2-way individual dampening adjustment with external reservoirs.
While they are made in Taiwan, they are not outsourced like most coilovers these days, but rather made at Silvers’ own facility. This allows Silvers to maintain the strict quality control and fast production times.
They are also highly customizable with custom spring rates with valving to match, Swift Springs, super low option and more.
These coilovers have a lot of positive reviews online and many happy customers, and come with an 18 month warranty, making these a great option that is a little more budget friendly.
NOTE: These are only made for the RWD model at this time, so if you have a AWD Q50, you’ll have to go with another kit.

The ride height adjustment on these is done by the shock body, giving you full suspension travel at all ride heights.
The dampers are monotube and give you 36 levels on dampening adjustments, which adjusts the compression and rebound simultaneously, to allow you to fine tune the ride stiffness and quickly switch between road and track.
While I would personally opt for the BC Racing BC Series at this price level, the Ksport Kontrol Pros are another decent affordable kit that can handle both street and track.
NOTE: These are currently only made for the RWD Q50.

Spring Rates: 12 Kg front, 8 Kg rear
Price: $995
Just scraping in under the $1000 mark, if you are on a budget, the Yellow Speeds are one of your best choices.
Designed as a performance coilover, these have a great reputation from people using them both on and off the track. Yellow Speed themselves are actively involved in motorsport, which allows them to produce parts that perform.
These offer shock body ride height adjustment which give you full suspension travel at all heights, as well as 33-level dampening adjustment from monotube dampers.
For a relatively cheap coilover that will give you good performance, the Yellow Speed Dynamic Pro Sports are one of the best kits you’ll find. They also come with a 2 year warranty which is one of the best in this price range.

TEIN Flex Z
Lowering: RWD: 0.6- 3.9″ Front, 0.0-5.7″ Rear – Red Sport 400: 1.2- 3.5″ Front, 0.0- 4.7″ Rear
Dampening adjustable: 16-level compression/rebound simultaneous (1-way)
Spring Rates: 12 Kg front, 8 Kg rear
Price: $849
The TEIN Flex Z’s are easily one of the best coilover kits you are going to find under $1000. Despite the low price, TEIN has put together a very high quality kit that has some serious engineering behind it.
One of the most amazing things about this kit is that TEIN makes them specific to the region it is being sold to, in order to match the conditions that the kit is likely to see – whether that’s rough roads, harsh weather or something else.
This allows them to make the best kit possible for the customer, and is something I have not heard of any other company doing.
The dampers in the Flex Z’s are a twin tube design, which TEIN has chosen for extra ride comfort on the street. The smooth stroke of the twin tubes allows the dampers to follow bumps and rough roads better, making for a more comfortable ride at low speeds while keeping stability at high speeds.
They are also 16-level dampening adjustable, which is done with an “ADVANCE needle”, allowing you to fine tune the ride for both road and track use. This kit is also compatible with TEIN’s EDFC system which is an electronic dampening adjustment system that allows you to change the damper settings from inside the car, even while driving.
The oil used in these dampers is specially formulated to maintain a stable viscosity at all temperatures, which allows the dampers to have a smooth stroke and stable damping in all conditions. It also has anti-foaming properties which make these dampers suitable for intensive performance driving, even for extended periods.
Ride height adjustment is done by the shock body, which ensures that you retain full suspension travel at all heights, making for not only a more comfortable ride and better handling but also making sure the dampers last longer.
TEIN springs are well known for their resistance to sagging and are made from cold formed high-tensile SAE9254 steel, which ensures a long life and increased stability. They are powder coated with TEIN’s patented powder coat to prevent chipping or corrosion, even in the harshest weather.
Speaking of their powder coat, the shock bodies are also coated in TEIN’s special patented powder coat which is formulated to be extremely corrosion resistant. The adjustment threads have a special ZT coating making them resistant to corrosion in all weather conditions.
While these dampers are not rebuildable, TEIN has instead made them so that the damper insert can be purchased for replacement. Meaning that when you need to replace the dampers, you simply order new ones and swap them in.
Not only does this mean that you don’t have to send the coilovers to TEIN and pay for shipping, but you also won’t have to wait several weeks for them to get rebuilt. Instead, you can just swap the dampers out like you would if you were replacing the suspension.
TEIN have done it this way to keep the price of the kit low and to make it easier for the customer to swap them when the time comes. They will also revalve the dampers to suit whichever spring rates or settings you specify, so if you have decided to change the spring rate, they’ll make sure the dampers match.
All this for under $1000, TEIN have really put a lot of effort to make a superb kit for an extremely low price. You will have a hard time finding something better at this price level.
NOTE: Only made for RWD models at this time.
Features include:
- Ride height adjustable by the shock body
- 16-level dampening adjustable
- Twin tube dampers for increased road comfort
- Special damper oil to withstand intensive driving

Dampening adjustable: 16-level, 1-way
Spring rates: 10 Kg front, 8 Kg rear
Price: $675
The Godspeed MonoSS are an excellent option for those on a tight budget looking to lower their Q50.
These coilovers are specifically designed to offer the perfect balance of performance and affordability, and give you a surprising amount of features given the very low price.
The springs are made from high strength SAE9252 steel, and ride height adjustment is done by the shock body to ensure you have full suspension travel at all heights. They typically give you 1-3 inches of lowering compared to stock, depending on the model.
The dampers are 52mm monotubes made of “carbon seamless steel” which give you 16-level dampening adjustment. They are designed to handle street driving as well as track days, and these dampers make it easy to adjust the settings quickly when you need to.
The dampers also feature “racing grade shock oil with a high viscosity index” and a “Performance Internal Piston” according to Godspeed.
They come with a 1 year warranty and the dampers can be rebuilt.
They won’t be quite as comfortable as some of the more expensive options, but for the price they are definitely decent.
Considering the low price and many positive reviews, they are a great option if you are on a budget but still want a decent coilover that can handle occasional track use.
NOTE: Only made for RWD models at this time
Features include:
- Ride height adjustment by the shock body

Designed primarily as a street coilover, they are made to allow you to lower your car on a budget and retain a comfortable ride.
They come with a wide range of features including ride height adjustment by the shock body, dampening adjustment, aluminium strut mounts and more.

Features include:
- Ride height adjustment by the shock body
- 15-level dampening adjustment
- Aluminium strut mounts
- Monotube dampers
- 1 year warranty
Benefits of Installing Coilovers on Your Q50
The top 2 reasons people install coilovers are:
- To lower the ride height for aesthetic reasons
- To improve the handling performance of the car
No matter which of these two you are looking to achieve (or both), coilovers are one of the best choices you have.
Coilovers were originally designed for race cars to maximize handling performance and make it easy to quickly swap springs and adjust settings.
They have since been adapted for road use as a way to allow people to set the perfect ride height as well as tune the suspension to match their particular car’s setup as well as the driver’s desires.
Most coilovers kits these days also have dampening adjustment which allows you to fine tune the damper settings to be stiffer or softer depending on your needs, and quickly change them if you need to (if you go to the track, for instance).
While you could opt for air suspension if you are just looking to lower your car (I cover air bag suspension vs coilovers here in detail), coilovers give you several benefits that air suspension does not:
- Coilovers are much more reliable, they won’t pop a bag or leak and leave you stranded
- They are usually significantly cheaper than air suspension
- Your car will handle better than with air bags
- They will handle regular track use much better than 99% of air suspension systems
- They are also lighter than air suspension
So, while air suspension certainly has its uses, for most people who want to either lower their car and improve its handling performance, coilovers are the way to go.
