Precision Front Strut Tower Brace Engineered for the Toyota Yaris NCP91
The Cusco Front Strut Bar CUS900 540 A is a direct-fit front strut tower brace manufactured for the Toyota Yaris NCP91 chassis, designed to reduce front-end flex under cornering loads by connecting the left and right front strut towers with a rigid brace. By tying the strut towers together the CUS900 540 A limits chassis twist through corners, improving turn-in sharpness and reducing understeer for a more connected steering feel on winding roads and track events. Cusco is a leading Japanese performance suspension brand with decades of motorsport heritage in the JDM performance market.

FAQ
What is the CUS900 540 A?The CUS900 540 A is a Cusco front strut tower bar engineered for the Toyota Yaris NCP91 chassis. It connects the front left and right strut towers to reduce body flex under cornering and improve steering response and front-end rigidity.
Does CUS900 540 A fit the GR Yaris?No. CUS900 540 A is designed for the Toyota Yaris NCP91 platform, not the GR Yaris (GXPA16). The GR Yaris requires a separate Cusco part number specific to its distinct strut tower geometry and chassis.
What is the NCP91 Yaris?The NCP91 is the internal chassis code for the second-generation Toyota Yaris (Vitz) sold globally between approximately 2005 and 2012. It is the generation preceding the GR Yaris and is commonly used for grassroots circuit racing and time attack builds in Japan and internationally.
How does a strut bar improve handling?A front strut bar ties the left and right strut towers together, preventing them from flexing outward independently under cornering loads. This maintains consistent suspension geometry through corners, improving turn-in precision and reducing the vague feeling from chassis flex.
Does the CUS900 540 A require drilling or permanent modification?No. The CUS900 540 A bolts directly to the existing strut tower mounting bolts on the NCP91 Yaris without drilling or permanent modification.
Is the CUS900 540 A compatible with aftermarket coilovers?The CUS900 540 A mounts to the strut tower mounting points and is generally compatible with aftermarket coilovers installed on the NCP91 platform. Confirm clearance with your specific coilover brand before purchasing.
Is this the Type A or Type B Cusco strut bar?The CUS900 540 A is the Type A configuration for the Toyota Yaris NCP91 platform. Cusco uses Type A to designate the primary straight-brace design for each application.
How long does installation take?CUS900 540 A installs in approximately 20 to 40 minutes using basic hand tools. No special tools or vehicle lift is required for installation access.
Installation Overview
- Open the hood and locate the front strut tower mounting bolts on each side
- Loosen and remove the strut tower top nuts on both sides, keeping the strut from dropping
- Position the CUS900 540 A brace feet over the strut tower studs on each side
- Thread the mounting hardware through the brace feet and strut tower studs
- Torque all mounting hardware to Cusco-specified torque values
- Verify there is no contact with the hood or engine bay components in the closed position
- Test drive and confirm hood closure is unaffected before regular use
