Black Rhino Wheels offers a range of Flow Form Technology (FFT) wheels. Many Black Rhino are manufactured using a highly advanced production technique called flow forming wheels. The rim of the wheels is forged at high pressure while the wheel is spun at high speed. This alters the molecular structure and enhances the strength of the alloy. The benefit is a much lighter weight than a regular cast wheel. Most importantly, the weight saving is in the outer rim of the wheel which dramatically reduces rotational mass and enhances vehicle performance.
