Cusco Coilovers, Braces & Performance Parts

What This Brand Covers

Cusco is a Japanese performance parts manufacturer with over 40 years of motorsports experience, engineering coilovers, chassis braces, differentials, and suspension components for Japanese domestic market race cars and street performance builds. The catalog is built around sport compact and all wheel drive platforms where precise chassis control and reduced flex translate directly into faster lap times and sharper street handling.

Brand Focus

Cusco designs almost exclusively for Japanese performance platforms including Subaru, Toyota, Mazda, Honda, Mitsubishi, and Nissan, with motorsport proven parts used by professional teams in Japanese racing series as well as enthusiasts building time attack and autocross cars.

Coilovers and Suspension

Cusco Street Zero and Street Zero A coilover kits are height adjustable and offer adjustable damping force, letting owners dial in a comfort biased street setup or a stiffer track oriented ride. The racing coilover lineup targets time attack and competition builds where maximum handling stiffness takes priority over ride comfort.

Coilover Kits

Coilover kits are a popular starting point for WRX, STI, 86, BRZ, and Miata owners looking to lower ride height while gaining independent adjustment of compression and rebound damping for street or track use.

Chassis Bracing and Strut Bars

Front and rear strut tower braces, triangulated lower arm bars, floor braces, and multi point chassis reinforcement bars reduce chassis flex under hard cornering. Cusco offers an extensive chassis reinforcement catalog for the WRX STI, including roll center adjusters that help correct suspension geometry after lowering.

Strut Tower Braces

Strut tower braces connect the left and right strut towers to reduce flex during hard cornering, improving steering response and giving a more predictable feel on cars used for autocross or track days.

Differentials and Drivetrain

Cusco limited slip differentials and differential braces improve traction and reduce chassis flex on all wheel drive platforms like the WRX, STI, and Evo. These upgrades are popular for track and autocross builds where consistent power delivery to all four wheels matters most.

Limited Slip Differentials

LSD units help both front and rear wheels maintain traction under acceleration and through corners, reducing wheel spin on one side and improving overall drivetrain efficiency for AWD sport compact builds.

Sway Bars and Alignment Components

Cusco front and rear sway bars in multiple diameters let owners fine tune understeer and oversteer balance, while adjustable control arms and camber kits allow precise alignment correction after lowering springs or coilovers are installed.

Adjustable Control Arms

Adjustable lower and upper control arms restore proper alignment geometry on lowered cars, correcting camber and toe that shift out of factory specification once ride height is changed.

Roll Cages and Safety

Cusco roll cages and safety components are built to motorsport tolerances for track day and competition builds, with touch up paint and hardware available to maintain cages already installed in a chassis.

Ignition and Interior Components

Cusco Type 2 high spark power direct ignition coil packs improve spark energy on Subaru FA20, FA24, and FB24 engines, while shift knobs, catch cans, and service parts round out the catalog for builds focused on both performance and cabin details.

Platform Coverage

Cusco parts fit the Subaru WRX and STI, Impreza, and Forester, Toyota 86 and GR86, Mazda Miata and RX-7, Honda Civic, S2000, and CR-V, Mitsubishi Evo, and Nissan 240SX, Skyline, 350Z, and GT-R platforms.
