| Product Description: 1 Pair (Axle Set) of 20mm hub centric wheel spacers. These are the superior bolt-on type of wheel spacer. Made from Aircraft Quality 6061-T6 Aluminium Alloy with steel threaded inserts. Bolts made to ISO 898-1 Grade 10.9 for high tensile strength New & Boxed. Fits: BMW 4 Series F32 Coupe, F33 Convertible & F36 Gran Coupe Specification: PCD: 5x120mm Hub: 72.56mm Supplied with M14 x 1.25 Shallow-head Bolts Good to know: 6061 Aluminium is an alloy made up of magnesium and silicon which allows for a very light spacer. T6 is a multi-stage heat treatment procedure that increases the strength of the alloy. The Spacer is attached to the hub using the bolts supplied in the kit. The supplied bolts need to be removed from the spacers and are then inserted through the non-threaded holes into the hub to attach the spacer. The standard wheel bolts then go into the threaded holes in the spacer to attach the wheel. In some cases, the standard wheel bolts may require shortening or shorter bolts can be fitted. The bolts supplied are the correct length when the above instructions are followed (this note is included due to incorrect installations leading to complaints that the bolts are not long enough, or that the spacers don't fit!) Always make sure the Spacer mounts on to the face of the hub with no restriction before tightening the bolts. Due to the restriction in available depth for 20mm spacers, it may be necessary to shorten the standard wheel bolts, or shortened bolts can be fitted if required. Only use hand tools to install and tighten all nuts/bolts. These spacers should only be fitted by persons with relevant training and experience.
