Coilovers - By car

Coilovers for the Infiniti Q50 and Q60

A Q50 coilover kit is a height- and damping-adjustable suspension that replaces the Infiniti Q50/Q60 factory struts and springs, usually dropping the car 1-2 inches. Budget street kits (BC Racing BR, Godspeed MonoSS) start under $700; higher-end kits (KW Variant 3) cost more. RWD and AWD Q50s need different parts.

This page compiles fitment data from coilover manufacturers and retailer listings rather than first-hand testing; every spec below links back to the page it came from.

One chassis, two drivetrains

The Q50 sedan and Q60 coupe have run on the same V37 chassis since 2014, so most coilover brands cover both under a single Q50/Q60 listing. The split that actually matters for fitment is RWD versus AWD, and whether the car has the factory Dynamic Digital Suspension (DDS) electronic dampers - most street coilover kits replace those dampers outright and are listed as fitting AWD cars without DDS, per BC Racing's AWD listing and Megan Racing's AWD product page.

A second wrinkle shows up on the front lower mount: depending on year and trim, retailers list the Q50's front strut as eyelet-type, ball-type, or fork-type, and some brands sell separate SKUs for each. Megan Racing's RWD kit, for example, is sold specifically for the "eyelet type front lower mount only" variant, while Godspeed's MonoSS targets the ball-type front strut. Check your car's front lower mount style against the retailer's fitment notes before ordering. See the brand pages for BC Racing, Megan Racing, and Godspeed for more on each line.

How much drop to expect

Drop figures are kit-specific rather than tied to model year. BC Racing's listing for the Q50 states the BR kit can lower the car roughly 1-2 inches, with factory ride height not achievable on most applications. KW's Variant 3 is more conservative, with a published 15-35mm (about 0.6-1.4 in) adjustment range front and rear on the Q50 2WD kit. Megan Racing and Godspeed publish spring rates (see the fitment table below) rather than a drop figure, so expect a similar street-friendly range unless you wind the kit all the way down.

If a daily-driver ride is the goal, start the kit near the middle of its range rather than at max drop - compare that approach against lowering springs if full adjustability is not a priority, or read whether coilovers are worth it for your use case first.

Alignment, camber, and tire clearance

Any Q50/Q60 coilover install changes ride height enough to throw off factory camber and toe, so budget for a four-wheel alignment right after installation - see coilover installation and cost for what that typically adds to the job. At the low end of a kit's range, stock control arms and strut mounts may run out of negative camber adjustment; adjustable front camber plates or rear camber arms are the usual fix once you are past a mild drop.

Staggered wheel and tire setups common on Q50/Q60 builds are worth rechecking against your specific offset once the car is lowered, since fender and strut clearance changes with ride height. Keep the manufacturer's install guide and a coilover spanner wrench on hand for re-adjusting height after the alignment settles the suspension.

Choosing between these kits

For a daily that just needs a cleaner stance, the Godspeed MonoSS and BC Racing BR sit at the budget end, both street-tunable with 16 to 30 damping positions. Megan Racing's EZ II lands in similar territory with simpler 15-way damping. D2 Racing's RS kit adds 36-way damping and full ride-height adjustability independent of spring preload for a bit more tuning range at a mid-range price. KW's Variant 3 is the step up: separately adjustable rebound and compression circuits and a narrower, more controlled drop range, aimed at drivers who want a firmer, track-capable setup without giving up daily usability.

Browse the full coilovers hub or the best coilovers guide for how these brands compare outside the Q50/Q60 specifically, and check how to adjust coilovers before you start dialing in ride height.

What a 1.5" drop looks like

Most street-oriented Q50/Q60 kits land around 1-2 inches of drop at a comfortable daily setting; KW's Variant 3 is tighter, at roughly 0.6-1.4 inches front and rear.

FAQ

Do I need different coilovers for Q50 AWD versus RWD?

Yes. Nearly every brand sells separate part numbers for RWD and AWD Q50/Q60 models, and AWD kits are commonly listed as fitting cars without the factory DDS electronic dampers.

Will aftermarket coilovers work with Infiniti's Dynamic Digital Suspension (DDS)?

Most aftermarket coilover kits, including BC Racing's BR line, do not interface with the factory electronic damping control and are built for cars without it. Check each listing's DDS note before ordering.

How much does a Q50 drop with coilovers?

Based on manufacturer listings, expect roughly 1-2 inches on street-tuned kits like BC Racing BR, and a narrower 0.6-1.4 inches on KW's Variant 3.

Do Q50 coilovers fit the Q60 coupe too?

Often yes, since both share the V37 chassis, but confirm the specific years and DDS status on the listing - some kits list the Q50 and Q60 separately with slightly different year ranges.

What's the difference between eyelet, ball, and fork-type front lower mounts?

These describe how the coilover's front lower mount bolts to the car's factory knuckle or arm. Some brands sell one universal mount style and others split the Q50 fitment by mount type, so matching your car's mount style to the correct SKU matters more than matching the model year alone.

Does lowering a Q50 require an alignment?

Yes, a four-wheel alignment is standard practice after any coilover install, and camber plates or arms may be needed if you run near the bottom of a kit's drop range.
