Description

The CUSCO S-MCB Rear Bar Upgrade Kit is a direct, performance-focused upgrade path for existing CUSCO rear strut bar users, allowing them to convert their current setup to the advanced S-MCB (Sheet Molding Carbon & Basalt) specification. This upgrade provides a significant increase in rigidity, weight savings, and vibration damping by simply replacing the existing rear bar with a cutting-edge S-MCB bar, enhancing rear chassis stability and handling precision.

Product Highlights

🔄 Direct S-MCB Upgrade for Existing CUSCO Owners
Designed specifically for customers already using a CUSCO rear strut bar. This kit allows for a straightforward upgrade to S-MCB technology by replacing only the rear bar, utilizing your existing mounting brackets and hardware.

⚡ Enhanced Rigidity & Weight Reduction
By swapping to an S-MCB composite bar, you gain a substantial increase in torsional stiffness and a reduction in unsprung mass, resulting in sharper rear-end response, improved chassis feedback, and reduced overall vehicle weight.

🏗️ Two Performance Tiers Available:

• S-MCB1000: Offers a balanced increase in rigidity and damping for street and performance driving.

• S-MCB3000: Provides maximum stiffness and structural integrity for competitive track use and ultimate chassis response.

🔧 Simple Bar-Only Replacement
A cost-effective and efficient upgrade—no need to purchase an entire new strut bar kit. Note: This upgrade is for the REAR BAR ONLY. The front bar cannot be replaced due to different bracket designs.

🎯 Compatible with Both Early & Late GR Yaris
Engineered for seamless fitment on both early and late-model GR Yaris (GXPA16), ensuring broad compatibility and consistent performance across the platform.
