The installation of spacer rings to increase a vehicle's track width or to equalize offset is not recommended by Porsche. Porsche will accept no liability
for damage resulting from the use of non-approved spacer rings. Please inform your customers about the hazards of such installations.
Do not perform any aftermarket installations.
"N0", "N1", "N2", "N3" indicates a specification identification of the tires. The complete "N" number must be present and visible on the outside of the
