Wisefab Rear Suspension Kit – Chevrolet Corvette C5 / C6 (1997–2013) | Formula Drift Legal | Full Adjustability | Spherical Bearing Conversion | WFC61

The Wisefab Corvette C5/C6 rear suspension kit is a motorsport-grade rear suspension solution engineered to push the performance limits of the C5 and C6 Corvette platform. Designed and manufactured by Wisefab — a Finnish suspension engineering company with deep roots in Formula Drift, time attack, and circuit racing — the WFC61 delivers the full range of adjustability, rigidity, and safety features demanded by competitive motorsport, while remaining Formula Drift legal for competition use. The OE knuckle is retained and upgraded with a spherical bearing conversion, preserving the factory geometry foundation while eliminating the compliance and deflection of rubber bushings.

Key Features

• Formula Drift Legal: The WFC61 is engineered and approved for Formula Drift competition — the ultimate validation of a rear suspension kit’s design integrity, adjustability range, and safety compliance. Suitable for FD Pro, FD Pro2, and amateur drift competition, as well as time attack and circuit racing applications
• Double Adjusters on Each Arm – Quick and Easy Alignment: Every arm in the kit features double adjusters — allowing quick, precise alignment adjustment without removing the arm from the vehicle. Double adjusters provide independent control of arm length from both ends, enabling faster corner-weight and alignment changes between sessions and eliminating the need to fully disassemble the suspension for alignment corrections
• Bump-Steer Bracket on Toe Arm – Rigidity and Dynamic Toe Control: A dedicated bump-steer bracket is integrated into the toe arm — adding structural rigidity to the toe arm assembly and enabling dynamic toe adjustment to tune rear toe behaviour through the suspension travel range. Controlling bump-steer at the rear is critical for predictable handling balance in high-speed cornering and during aggressive weight transfer events in drifting and time attack
• OE Knuckle Retained – Spherical Bearing Conversion: The factory Corvette knuckle is retained and upgraded with Wisefab’s spherical bearing conversion at the upper knuckle mount — eliminating the compliance and deflection of the OE rubber bushing while preserving the factory knuckle geometry. Spherical bearings provide a rigid, zero-deflection pivot point that maintains consistent suspension geometry under load, critical for predictable handling at the limit
• Detachable Lower Shock Mount – Effortless Coilover Removal: The lower shock mount is designed to detach without disturbing the rest of the suspension geometry — allowing coilover removal and installation without disassembling the entire rear suspension. A significant time-saving feature for teams making spring rate or damper changes between sessions
• Built-In Safety Features – Chassis Protection on Impact: Wisefab has engineered deliberate safety features into the WFC61 to help protect the chassis during impact events — components are designed to absorb and redirect impact energy in a controlled manner, reducing the risk of chassis damage in competition incidents. A critical consideration for any motorsport suspension kit used in contact-risk environments
• Wisefab Engineering Quality: Designed and manufactured by Wisefab — a Finnish motorsport suspension engineering company with an established track record in Formula Drift, time attack, and circuit racing globally. Wisefab kits are used by professional and semi-professional teams worldwide and are known for their precision engineering, material quality, and real-world motorsport validation
