The Complete Q50 & Q60 Handling Upgrade Guide: Brakes, Suspension & Aero

The Q50 (2014–present) and Q60 (2017–2022) share a platform and most of their suspension and braking hardware, which makes them two of the easier Infiniti models to source performance parts for. Whether you're maintaining a base trim or pushing a Red Sport 400, the upgrade path looks similar. Start with the basics: wheels & rims, tires, center caps, and lug nuts are the fastest way to change how the car looks and how it puts power down. A wider, lighter wheel paired with the right tire compound makes a bigger difference in daily driving than most bolt-on parts. From there, brakes are the next logical step — brake calipers, brake rotors, and brake pads all scale with your use case, from daily-driver ceramic pads to track-ready big brake kits, especially important on the twin-turbo Red Sport 400 models that carry more speed into corners. Suspension is where Q50 and Q60 owners see the most noticeable difference. A basic suspension refresh — new bushings, mounts, and worn components — restores factory handling, but coilovers and lowering springs are the go-to for a lower stance and adjustable ride height. Underneath, control arms, tie rods, ball joints, and wheel bearings wear out over time regardless of how the car is driven, and replacing them as a set restores precision to the steering. CV axles and the steering racks and power steering pumps that feed them are less glamorous but critical — a worn steering rack shows up as play in the wheel long before it fails completely. For the exterior side of handling, spoilers, splitters, side skirts, and diffusers aren't just styling — a front splitter and rear diffuser genuinely reduce lift at highway speeds, which matters on a car capable of the Q50/Q60's top speeds. Whatever combination you're planning, every part in our catalog lists exact fitment by model, year, and trim, so you're not guessing whether a Red Sport 400 part fits your base 3.0t.
