They are constructed of 7075-T6 super strong aluminum alloy and hard black anodized for the ultimate in strength and corrosion resistance. Spacers are designed to perfectly fit in the recessed portion of the rotors. All excess material has been removed to save weight and increase handling. Kit comes with 10 strong extended 12.9 tensile lugs / nuts. We are a 20 year + performance company and know the ultra high power levels that Teslas produce and how to design parts to handle Tesla's huge torque. 7075 alloy we use and tighter machining tolerances are far stronger and stable than the 6061 others offer. Plus we use 12.9 tensile strength bolts that are 120% stronger than most oem or competitors bolts.
