Infiniti G37 Coilovers

The G37 also wore the G37x, Q40 and Q60 badges over the years. It came as a coupe, a sedan, a convertible and the all-wheel drive G37x, and each body takes its own Infiniti G37 coilovers. Once you know which one you have, the rest is easy. Every kit we carry is below, by body, with BC Racing first.

Not sure which badge your car wears? Call 1-800-460-9106.

Animated illustration. It shows where coilovers sit on a car, not your exact kit. Depending on the car and the kit, coilovers can lean forward or back or stand straight up, and some cars use a separate spring and shock in the rear. Your ride height depends on the kit and how it is set up.

Start with the body style

How to tell which body you have

Four quick ways to tell which G37 you have, and what that means for the kit.

G37 coupe

The coupe has two doors, a fixed roof and rear drive. It arrived first, in August 2007, as a 2008 model. It later wore the Q60 name, and several brands list Q60 kits.

G37 sedan

The sedan has four doors and rear drive, and went on sale in September 2008 as a 2009 model. It later wore the Q40 name, with Q40 kits from BC Racing, Ksport and TEIN.

G37x

The x means all-wheel drive, coupe or sedan, and the Q40 and Q60 AWD cars follow the same rule. They take AWD kits, never the rear-drive ones.

G37 convertible

The convertible has its own BC Racing and Ksport kits, plus a BC kit for the Q60 convertible. Coupe kits that exclude the convertible will not fit.

BC Racing coilovers for the Infiniti G37

BC Racing kits for each body

BC Racing makes four series for the G37: BR, DS, ER and ZX. The rear-drive coupe and sedan can have all four, with a separate style rear or true rear coilovers. The G37x and the convertible come in BR and DS. The series for each kit is printed on its card. Free shipping on BC Racing kits in the continental US.

What BR, DS, ER and ZX mean on a G37

Here is a quick key to the four BC series sold for this car.

BR, all four bodies

BR is BC's street coilover, with a single-tube (monotube) shock and one 30-click knob that sets compression and rebound together. BC lists it for the coupe, sedan, G37x and convertible.

DS, all four bodies

DS uses the same single 30-click knob as BR, plus a digressive piston that is firmer on small movements. Like BR, it fits every G37 body.

ER, coupe and sedan

ER has an upright shock with an external oil reservoir and 30 clicks each for compression and rebound, set separately. It is for the rear-drive coupe and sedan.

ZX, coupe and sedan

ZX, which BC calls its "most track-tested" system, goes on the same rear-drive coupe and sedan as ER.

Separate or true rear

From the factory, the G37's multi-link rear keeps the shock and the spring apart. BC builds a separate style rear to match, or true rear coilovers with the spring on the damper.

With Swift Springs

To add Swift Springs to a BR, DS or ER kit, order through BC's Custom Build for BC Coilovers page. Call us and we will help set it up.

G37 kits from five more brands

Here is what each brand lists for the G37, and what makes each coilover different. To talk it over, call 1-800-460-9106.

Fortune Auto

Fortune Auto hand-assembles its kits in Powhatan, Virginia. It builds a separate style rear and a true style rear kit for the 2008 to 2013 G37.

KW

KW has two rear-drive coupe kits, one of them listed for both the G37 and the Q60, 2008 to 2015.

TEIN

TEIN coilovers for the G37 come as Flex Z, Mono Sport and Street Basis Z for the coupe and sedan, and the same three for the Q40 and the Q60.

Ksport

Ksport has a kit for every G37 body, plus Q40 and Q60 kits for 2014 to 2015. Its coupe and sedan kits are true rear.

Feal

Feal lists a 2008 to 2013 G37 kit and a 2007 to 2015 G37x AWD kit.

Swift Springs

Swift makes Sport springs for the sedan, the coupe, the G37x sedan and the G37x coupe, each listed to also fit the Q40 or Q60.

Kits for daily driving, weekends and show builds

Daily driver

If you are shopping for G37 sedan coilovers to commute on, go with a mild drop and soft damping. Lowering springs on their own are also an option.

Kits to look at: BC Racing BR or DS, TEIN Street Basis Z, Ksport, Swift Sport springs
Fun weekend drives

The coupe has a stiff body and a strong V6. G37 coupe coilovers with separate compression and rebound settings let you match the car to the road.

Kits to look at: Fortune Auto, BC Racing ER or ZX, TEIN Mono Sport, KW
Stance and show builds

True rear kits put ride height and preload on the damper, which gives you more room to tune how low the car sits.

Kits to look at: BC Racing true rear, Fortune Auto true style rear, Ksport, Feal

Before you buy: what G37 owners run into

Here is what G37 owners report most often on forums and in recalls and service bulletins, and what each point means for your coilovers.

Rear camber and toe drift when lowered
V36 sedan and coupe, 2007 to 2013

G35Driver owners report that lowering pushed rear camber past the factory minimum, and a rear camber and toe kit brought it back. Owners also note faster front tire wear when lowered, and that front alignment kits were scarce early on. The wide rear tires show camber wear quickly.

Before you install: Budget for a rear camber and toe kit, and front upper camber arms if you go low, and align the car right after the install.

4-Wheel Active Steer changes alignment parts
G37 coupe and sedan with 4WAS

One parts maker lists a rear camber and toe kit made for the 2007 to 2008 G37 without active steering. On G35Driver, one owner reports that a 4WAS G37 coupe owner found a rear camber kit too short, while a 4WAS G35 owner fitted it with no problems so far. Parts can differ on 4WAS cars.

Before you install: Confirm whether your car has 4WAS and check that any camber or toe kit is listed for it before you order.

G37 history

A stiffer FM chassis and a bigger V6

The G37 took over from the G35 with the new VQ37VHR V6 and an upgraded FM (front mid-ship) platform. Infiniti said the new platform was 36 percent stiffer than the one before it. It uses a double-wishbone front, and the multi-link rear keeps the shocks and springs apart.

Here is when each body and name came out.

  1. 2007
    The coupe arrivesThe second-generation G Coupe reached Infiniti retailers in August 2007, with 4-Wheel Active Steer as an option.
  2. 2008
    The sedan followsThe 2009 G37 Sedan went on sale in September 2008 with the 3.7-liter V6 as standard and a new seven-speed automatic option.
  3. 2009
    The convertibleThe convertible joined the range. BC Racing and Ksport list their convertible kits from 2009.
  4. Later
    New name tagsThe sedan, coupe and convertible carried on as the Q40 and Q60. Kits for those names are listed through 2015.

Check the badge and the body style, and the right G37 coilovers are easy to find.

Your G37 questions

Which Infiniti G37 coilovers fit my car?

Find your body first: coupe, sedan, convertible or all-wheel drive G37x. Rear-drive coupes and sedans then choose a separate style or true rear. The kit page confirms the fit, or call 1-800-460-9106.

Do G37 kits fit the Q40 or Q60?

Yes, for the 2014 to 2015 cars on the same V36 chassis. BC Racing, Ksport and TEIN list Q40 and Q60 kits, and KW and Swift Springs list some G37 kits to also fit them. The 2017 and newer Q60 is a different car with its own kits.

Is there a kit for the G25?

Ksport lists a 2008 to 2013 G25 coupe and sedan RWD kit (V36), excluding the convertible, with true rear coilovers. You will find it in the coupe and sedan sections of this page.

Can I put coupe coilovers on my convertible?

No. BC Racing and Ksport build separate convertible kits, and Ksport's coupe and sedan kits are named "excluding convertible."

What BC series can I order for a G37?

Rear-drive coupes and sedans get all four, BR, DS, ER and ZX, with either rear style. The G37x and convertible kits are BR and DS.

My coupe has 4-Wheel Active Steer. Does that change anything?

Infiniti listed 4-Wheel Active Steer as an option on the G37 Coupe. Tell us when you call so we can check the kit against your car before you order.

Do you have lowering springs for the G37?

Yes. Swift Springs lists Sport springs for the G37 sedan and coupe and for the G37x sedan and coupe.

How long is the BC warranty on a G37 kit?

BC Racing North America currently lists a two-year limited warranty on full kit orders, subject to its warranty terms. Each of the other brands sets its own warranty terms.
