MPI-QR-RX-06-MK3: The Ultimate Quick-Release Solution
The MPI-QR-RX-06-MK3 redefines quick-release technology, offering PATENTED DESIGN unmatched durability, precision, and performance. Designed for applications using the COSWORTH CCW MK3 steering wheel, this cutting-edge system features a 6x70mm M5 bolt pattern and a bolt/weld-on column male pin, created using the same core design of the RX03 used in the majority of Indycar. This mounting system has been engineered to create the ultimate quick release solution for the Cosworth CCW MK3 steering wheel.
At its core, the RX06 features an innovative three-dowel pin locking mechanism, surpassing industry standards for superior reliability and stability. The self-centering, push-on, one-position mechanism, equipped with a six-faced, spline-less pin design, eliminates the need to pull a collar for engagement. This ensures one-directional, push-on steering wheel alignment, allowing for quick and hassle-free driver changes during high-pressure moments.
The RX06 guarantees a firm, zero-play connection, delivering a secure and smooth steering wheel attachment with free disengagement and virtually no play. An orange visual marker provides immediate confirmation of proper engagement for both drivers and crew, enhancing safety during critical moments. Weighing just 199 grams, the ultra-lightweight Featherlite body optimizes performance without compromising strength.
Designed to overcome common issues found in competitor systems, the RX06 eliminates seize-up challenges typical of Krontec quick releases and offers greater longevity with significantly less free play compared to SPA QR systems.
The RX06-MK3 has been specially engineered alongside the COSWORTH team to meet the proprietary needs of the COSWORTH CCW MK3 steering wheel, as well as being fully compatible with the SOURIAU 8STA connector.
The RX06 ’s advanced design incorporates four distinct engagement points:
- Spline tip into body base for foundational stability.
- Three dowel pins into ramp faces for enhanced locking.
- Spline base and body mouth for added security.
- Spline tabs and notches for precise alignment.
These features achieve near-zero play without the risk of seizing, while the tapered column spline-less pin ensures smooth engagement and release, making steering wheel removal during endurance driver changes efficient and error-free.
Tested and approved to SFI standards, the RX06 meets the highest safety requirements for professional motorsports. With its robust construction, innovative features, versatile mounting options, and proven performance, the MPI-QR-RX06-MK3 is the ultimate choice for the most demanding motorsport applications.
