The extended length M14x1.5 female threaded stainless steel lug guide tool is for use with 2020+ C8 Corvettes and other vehicles which use M14x1.5 studs. The M12x1.5 tool is for use with C4 thru C7 Corvettes and other vehicles which use M12x1.5 studs.The M12x1.25 tools are for use with Nissan GT-R and 370Z wheel studs (except GT-R Nismo). The 1/2"-20 tools fit Viper wheel studs and Mustang wheel studs (through model year 2014). Using at least three of the 200mm long female threaded lug guide tools helps to avoid damaging the brake caliper, rotor, and wheel when installing a wheel on vehicles with big brakes or ceramic rotors. Because of the extra length of this tool, at least three tools should be used to minimize the weight of the wheel/tire combination on each tool. The tools are sold in sets of three (3) or sets of five (5). Storage cases are included with the tools.
