To help reduce tire slip during drag-strip launches, all BST wheels 6.25" and wider come standard with BST’s exclusive Ultra-High-Speed (UHS) Coating technology, a mixture of chemical adhesive and abrasives which create a sandpaper-like surface to reduce tire slippage on the rim. This process, used successfully in MotoGP racing since 2005, was developed to combat front-tire slippage during hard braking as well as rear tire slippage during hard launches. UHS can be added to any size rim, front or rear.
