Introducing the QR-R1-56 meticulously crafted to cater to the diverse needs of both GT and drag racing enthusiasts. This innovative quick release boasts dual compatibility with the universally recognized 6x70mm bolt pattern, ideal for GT and road cars worldwide, alongside the specialized 5-bolt Grant pattern, favored in drag racing circles.
