Popular Upgrades

Cusco coilover kits, strut tower braces, and rear member braces are the most popular products for Subaru WRX and STI, Toyota 86 and GR86, Mazda Miata, Honda Civic, and Mitsubishi Evo platforms. Cusco limited-slip differentials and differential braces provide improved traction and reduced chassis flex for track and autocross builds on AWD platforms. Cusco adjustable control arms and camber kits allow precise alignment correction after lowering springs or coilovers are installed.

What chassis bracing does Cusco make for the Subaru WRX STI?

Cusco makes an extensive chassis reinforcement catalog for the WRX STI, including front and rear strut tower braces, triangulated lower arm bars, floor braces, roll center adjusters, and multi-point chassis reinforcement bars that connect multiple brace points simultaneously. Full chassis brace packages are popular for STI time attack and track day builds where chassis rigidity directly translates to more predictable handling and faster steering response.

Are Cusco coilovers adjustable for ride height and damping?

Yes. Cusco coilover kits are fully height-adjustable and most models offer adjustable damping force, allowing the suspension to be tuned between street comfort and track stiffness. The Street Zero and Street Zero A models are designed for street use with a comfort bias, while the racing coilover lineup targets time attack and competition builds where maximum handling stiffness is needed regardless of comfort impact.
